#how to calculate cement quantity in brickwork

[civilguidelines]

To calculate the quantity of sand and bricks required for 1 square meter of brick masonry (1:4) with a standard brick size of 190mm x 90mm x 90mm, follow these steps:

1. Number of Bricks Required

The standard brick size (with mortar) is 200mm x 100mm x 100mm.

Volume of 1 brick with mortar = 0.2 x 0.1 x 0.1 = 0.002 m3

For 1m2 of wall (assuming a thickness of one brick, i.e., 0.1m):

Total volume = 1 x 0.1 = 0.1 m3

Number of bricks = 0.1 / 0.002 = 50 bricks

2. Mortar Calculation

Mortar Ratio = 1:4 (Cement:Sand)

Mortar Thickness = 10mm (0.01m)

Mortar Volume = 25-30% of brickwork volume

Taking 30% of 0.1 m3, mortar required = 0.03 m3

3. Dry Volume of Mortar

Wet mortar volume = 0.03 m3

Dry volume of mortar = 1.33 x Wet volume = 1.33 x 0.03 = 0.04 m3

4. Sand Calculation

Cement-Sand Ratio = 1:4, so total parts = 1+4 = 5

Sand required = (4/5) x 0.04 = 0.032 m3 = 32 liters (approximately 46 kg)

How to calculate mortar/Plaster?

How to calculate Area of wall plaster?

Area of Wall = L×H

Area of Wall = 12’×10′ = 120 sft

Thickness of plaster = 10mm = 0.375 Inch

Wet Volume of Mortar = Area × Thickness of plaster

Wet Volume=120×(0.375/12) = 3.75 Cft

0.375 divided by 12 to convert inch into foot

Dry Volume of mortar = 3.75×1.33= 4.98 Cft

Or 0.141 Cum

Now we will use dry volume to get Quantity of cement and sand

Ratio of mortar = 1:4

Sum of ratio = 5

Cement quantity calculation in mortar:

Quantity of Cement = (1÷5)×4.98 = 0.996 Cft

Cement = (1÷5)×0.141 = 0.0282 Cum

Density of cement = 1440kg/m3 or 40.77kg/cft

Multiply cft with 40.77 & cum with 1440 to get quantity of cement in KGs. Cement consumption in plaster 1:4.

Cft>>>> 0.996×40.77= 40.60 Kg

Cum>>> 0.0282×1440= 40.60 kg

To convert into Bags divide by 50 (50 kg in one bag of cement)

Or directly calculate cement bags from Volume:

Volume of cement bag= 0.034cum or 1.226cft

Cft>>> 0.996÷1.226 = 0.82 Bag

Cum>>> 0.0282÷0.034 = 0.82 Bag

Read also Quantity of concrete.

Sand quantity calculation in mortar:

Simply Multiply Dry Volume of cement by 4 (sand is 4 times of cement) OR

Sand = (4÷5)×4.98 = 3.984 Cft

Quantity of Sand = (4÷5)×0.141 = 0.112 Cum

As Sand is sold & purchased in CFT & CUM, so it don’t need to be converted

If you want to convert it into KGs then multiply Cft Volume with 45.30 and Cum volume with 1600.

Density of sand is 1600kg/m3 OR 45.30 kg/cft

cft>>> 3.984×45.30 = 180.47 kg

Cum>>> 0.112×1600 = 180.47 kg

Water cement ratio of mortar:

As water is about 0.45 to 0.50 times to cement. To maintain its strength and workability, water should be add with exact ratio.

as cement is 40.60 kg so the water should be added is 20.30 kg/Ltr.

If there is high volume of mortar or concrete, ready mix plaster and ready mix concrete can be used to save time and manpower.

How to calculate plastering cost? Just multiply the cement bag with rate of and quantity of sand with rate. Add labour cost for preparation of plaster work.

In this civil engineering video tutorial, you will learn how to work out the quantities of cement, sand and water in the mortar of any brickwork construction. Also learn how to calculate wastage.

The volume of mortar in a brick wall can be calculated as follow :-

Volume of brick wall = total volume of all bricks + volume of mortar

So, volume of mortar = Volume of brick wall – total volume of all bricks except mortar

The calculation is done in the following ways :

Total volume of bricks with mortar is taken as 10 cubic meter

The thickness of mortar is considered as 10 mm

The proportion of cement and sand = 1:6

The size of each brick = 190 mm x 90 mm x 90 mm

The size of brick with mortar = 200 mm x 100 mm x 100 mm (after adding 10 mm mortar thickness)

Volume of each brick along with mortar = Length x Breadth x Height = 0.2 x 0.1 x 0.1 = 0.002 cum (here, each is divided with 1000)

So, total numbers of bricks in 10 cum = 10 / 0.002 = 5000

The volume of each brick except mortar = 0.19 x 0.09 x 0.09 = 0.001539 cum

The volume required for 5000 numbers of bricks = 0.001539 x 5000 = 7.695 cum

So, volume of mortar = Volume of total brick work with mortar – Volume of total bricks = 10 – 7.695 = 2.305 cum (wet volume)

Because of frog filling, brick joint filling as well as wastage, the quantity is raised by 15%.

So, the volume of wet mortar = 2.305 + (15% of 2.305) = 2.651 cum or cubic meter.

To covert wet mortar to dry mortar add 33% as follow :-

Volume of dry mortar = 2.651 + (33% of 2.651) = 3.526 cum

The quantities of cement, sand and water will be calculated as follow :-

Cement = Volume of dry mortar x ratio of cement / sum of ratio x density of cement = 3.526 x 1/7 x 1440 = 725.348 = 14.51 bags (sum of ratio = 1+6 = 7)

Sand = Volume of dry mortar x ratio of sand / sum of ratio x 35.3147 (1 cum = 35.3147 cft) = 3.526 x 6/7 x 35.3147 = 107 cft or cubic feet

Suppose, the ratio of water and cement = 0.45

So, water / cement = 0.45

Water = 0.45 x cement = 0.45 x 725.348 = 326 litres.

How to calculate cement required for brickwork? Brick work calculation

If we are site workers or engineers then we must have known about to calculate the number of materials required in the construction. So, that we can schedule and do work efficiently. Here we will see how to calculate cement required for brickwork and also we will calculate the quantity of sand required to prepare mortar taking example of the wall.

Let us start from some basic stuff.

Cinder Block Foundations Vs Poured Concrete Molds

One exception occurs in Alaska, the place it is not uncommon to specify completely different frost depths for “heat,” “cold,” and “interior” foundations. For homes in the Anchorage, Alaska, space, the perimeter basis is usually categorized as heat, with a required depth of four or 5 ft. On the opposite hand, “cold” foundations, together with outdoors columns, could also be required to be as a lot as 10 feet deep. Try this link.

The most common approach to lay block is in a running bond sample the place the vertical head joints between blocks are offset by half the block's size from one course to the subsequent. Mortar is composed of cement, lime, clear, nicely-graded sand, and water, and is often classified into Types M, S, N, O, and K in accordance with ASTM C270 . Residential basis walls are typically constructed with Type M or Type S mortar, both of that are typically really helpful for load-bearing inside and exterior partitions, together with above- and under-grade applications. Residential basis walls are sometimes constructed with low- to medium-weight units due to the low compressive energy required.

How To Make Concrete Blocks With Henry

In the contiguous forty eight states, depths for footings vary from a minimum 12 inches in the South to as a lot as 6 toes in some northern localities. In light-frame properties, the first load combination usually governs masonry partitions. To simplify the calculations, the designer may conservatively assume that the wall story acts as a simple span with pinned ends, although such an assumption could are inclined to over-predict the stresses within the wall. Walls which are determined to have sufficient energy to resist shear and combined axial load and bending second generally satisfy unspecified deflection necessities.

For prescriptive design of masonry basis partitions in typical residential applications, a designer or builder could use the International One- and Two-Family Dwelling Code or the local residential constructing code. Plain concrete foundation walls provide serviceable buildings when they're adequately designed (see Section four.5.1.1). Shear friction is the switch of shear through friction between two faces of a crack. Shear friction additionally depends on resistance from protruding portions of concrete on both facet of the crack and by dowel action of the reinforcement that crosses the crack.

The design equations used later on this section are based mostly on ACI-318 and rules of engineering mechanics as described under. Moreover, the method is predicated on the assumption of uniform soil-bearing stress on the underside of the footing; due to this fact, walls and columns must be supported as shut as possible to the center of the footings. These rules of thumb generally result in a footing design that differs considerably from the plain concrete design provisions of Chapter 22 of ACI-318. It should also be understood that footing widths generally observe the width increments of normal excavation tools . Even though some designers and builders might specify one or two longitudinal No. four bars for wall footings, steel reinforcement just isn't required for residential-scale structures in typical soil circumstances.

Unreinforced concrete masonry walls have proven serviceable in tens of millions of properties. Builders and designers could, however, want to specify a nominal quantity of reinforcement even when such reinforcement just isn't required by evaluation. For example, it is not unusual to specify horizontal reinforcement to manage shrinkage cracking and to enhance the bond between intersecting partitions.

In those areas termite limitations or other particulars must be integrated into the design to dam hidden pathways leading from the soil into the construction between the froth insulation and the inspiration wall. For typical loading and soil situations, floor slabs, driveways, garage flooring, and residential sidewalks are constructed at a nominal four inches thick per ACI302•2.1. Where inside columns and cargo-bearing partitions bear on the slab, the slab is usually thickened and may be nominally bolstered. Monolithic slabs may also have thickened edges that provide a footing for structural loads from exterior load-bearing walls. The thickened edges might or may not be reinforced in normal residential follow.

However, you’re extra prone to need a contractor for walls with greater structural necessities. The specific kind of local block wall installer to rent is determined by the wall’s function.

When used, horizontal reinforcement is typically specified as a ladder or truss-sort wire reinforcement. It is commonly put in repeatedly in mortar joints at vertical intervals of 24 inches . The allowable stress design procedure outlined below describes an approach by which walls are designed in accordance with ACI-530•2.three. Although not discussed in detail herein, partitions may also be designed by following the power-based design methodology laid out in ACI-530. The equations under are used to examine perpendicular and parallel shear in masonry walls.

Poured concrete wall foundations are arguably stronger than cinder blocks. Poured walls have a greater lateral strength, which means they're ready to withstand more pressure from the water and the soil from the outside. A poured wall doesn’t have joints like a block wall so it's simpler to waterproof.

Other common makes use of for concrete block wall is interior hearth-rated partition partitions, and exterior backup wall for attachment of building envelope systems and façades. Foundation walls generally resist each an applied axial load from the construction above and an utilized lateral soil load from backfill. To be sure that the wall’s strength is enough, the designer should first determine slenderness effects in the wall. ACI-318•10.10 offers an approximation method to account for slenderness results in the wall; nonetheless, the slenderness ratio should not be greater than a hundred.

Sometimes, a specific design utilized with affordable engineering judgment ends in a more efficient and economical answer than that prescribed by the codes. The designer might elect to design the wall as either a reinforced or a plain concrete wall. In some instances, masonry or concrete basis walls incorporate a nominal quantity of metal reinforcement to control cracking. Engineering specifications typically require reinforcement of concrete or masonry foundation walls due to somewhat arbitrary limits on minimum steel-to-concrete ratios, even for “plain” concrete walls.

Cinder Block Cost

For this purpose, high seismic zones typically only permit fully grouted walls in their constructing codes. The American design code that guides design engineers in utilizing CMU as a structural system is the Masonry Standards Joint Committee's Building Code Requirements & Specification for Masonry Structures (TMS 402/ACI 530/ASCE 5). The local building division usually sets required frost depths. Often, the depths are highly conservative in accordance with frost depths skilled in purposes not relevant to residential foundations. The local design frost depth can vary considerably from that required by precise climate, soil, and utility circumstances.

Generally, concrete blocks are fabricated utilizing products corresponding to Portland cement, completely different aggregates such as stone or quartz, and water. The likelihood is also high that you have seen many concrete block houses that do not seem like they're made out of concrete block due to their external facings or coverings. The equations under examine perpendicular and parallel shear along side Figure 4.7. The “j” coefficient defines the distance between the middle of the compression space and the center of the tensile metal area; however, it is typically dismissed or approximated as 0.9. If greater parallel shear capability is required, it might be obtained in a manner just like that really helpful in the earlier part for unreinforced masonry design.

Depending on soil loads, evaluation should confirm standard residential foundation wall follow in typical circumstances. In most instances, a design for concrete or concrete masonry walls may be selected from the prescriptive tables in the relevant residential building code or the International One- and Two-Family Dwelling Code .

Walls And Brickwork

Which might make you suppose that at present’s builders would only want concrete block, nevertheless, that’s not the state of affairs. If the building codes and formational needs of the job allow it, numerous builders choose ‘cinder block’ as a result of it’s lighter in weight. Real concrete blocks are extremely heavy, and lifting them will get old fast. So consider it or not, modern cinder block– which is made utilizing volcanic pumice if there isn’t a coal plant nearby– can lead to actuality command a higher worth.

These publications, nonetheless, usually focus on column or wall design that is closely reinforced in accordance with design masses frequent in commercial development. Residential concrete walls are either plain or barely strengthened, with one layer of reinforcement sometimes placed near the center of the wall. Plain and reinforced concrete interplay diagrams for residential purposes and the strategies for deriving them may be found in Structural Design of Insulating Concrete Form Walls in Residential Construction . PCA additionally offers a computer program that plots interaction diagrams based mostly on person enter; this system is entitled PCA Column . Even though a plain concrete wall usually calculates as sufficient, the designer could elect to add a nominal amount of reinforcement for crack control or other reasons.

Based on the air-freezing index, Table 4.8 presents minimum “protected” frost depths for residential foundations. Figure four.12 depicts the air-freezing index, a local weather index carefully related to ground freezing depth.

This can sometimes put the wall in danger with constant moisture buildup or heavy moisture climate conditions. It comes as a ready mix and is poured into whatever form is needed.

What are Structural Insulated Panels?

SIPs (structural insulated panels) are pre-insulated panels that can form part of a building or whole buildings. The panels are made of either cement particle board (CPB) or, more commonly for self build, engineered wood-based sheets known as oriented strand boards (OSB). Two sheets of this are sandwiched together with a rigid insulation (such as polyurethane).

Tests on Siptec’s panels, for example, by the University of Surrey, show that they are up to five times stronger than a timber-frame structure.

SIPs have thermal and sound-insulation properties that comply with, or often significantly exceed, current Building Regulations and some incorporate a vapour-controlling membrane.

What forms do SIPs come in?

SIPs come as individual panels for walls, floors and roofs, or in kit form, ready to be joined together to make a whole house.

They can come with windows and doors already installed, plasterboard lining and first-fit electrics. A finished house built with SIPs can be clad with bricks, timber, render or stone.

What are the advantages and disadvantages of building walls with SIPS?

SIPs have a high U-value relative to their thickness, so maximising available room space. SIPs are similar to panelised timber frame in that they are prefabricated off site in a factory.

The use of Computer Aided Design (CAD) technology ensures that every panel is precision cut, so they are always straight and true. This means little to no construction waste is created and work needed on site is considerably reduced.

Although SIPs can be used as part of a conventional build, this is not as efficient in terms of time and materials, or as economical, as building a whole house from SIPs.

What are the advantages of building a whole house with SIPs?

Although it might look as though it is an expensive way to build, there are savings.

Fast construction

As the house can go up in a matter of days – construction is made simpler as window and door openings can be pre-cut, and the inside is battened to accept plasterboard while leaving gaps for the electrics – fewer tradespeople are needed and for a much shorter time than with a conventional build.

A four-bedroom house, for instance, can be erected and weatherproof in a minimum of five days. There is also less waste (you only get the materials you need) and mess to clear and dispose of.

Design flexibility

The lightweight nature of the panels can lead to a reduction in foundation loadings, giving the structural engineer flexibility of design, and often meaning a reduction in groundwork costs.

Eco Sips Homes have collaborated with award winning GD Lodge Architects in Glasgow and structural engineers, Cowal Design Consultants to deliver a stunning range of two to five-bedroom rural homes.

The wall panels in the structural SIPs building system are joined together with mini SIP joining splines to reduce thermal bridging. The panel core is graphite EPS insulation which is 100% recyclable.

This makes SIPs ideal for adding to existing structures, such as converting bungalows into two storey houses. Other applications include building a structure inside an existing shell for conversion projects, as infill panels for timber frame, or to create liveable roofspace.

Once the shell is complete, the external walls can then be finished in a huge variety of ways to create a traditional, contemporary or fusion aesthetic. Common finishings include traditional cavity and facing brickwork, timber cladding, brick slips and render systems.

Securing financing for your SIPs home

Some mortgage lenders are beginning to reduce their rates for borrowers with SIP-built houses.

What are the eco benefits?

Compared to some more conventional build methods, SIPs provide extremely thermally efficient, airtight homes.

“With the government’s commitment to lowering CO2 Emissions in construction, together with numerous announcements that all new homes will be zero carbon by 2020 – plus the launch of The Code for Sustainable Homes in May of 2007 – thermal insulation and lower air leakage requirements within dwellings will increase dramatically,” says Andrew Orriss of the UK SIP Association.

“By adopting the use of SIPs, these new requirements can easily be achieved, especially when the SIPs provider is integrated early enough in the design process to allow efficient and effective design.”

Lower energy bills

Because a whole SIP house will be very airtight and thermally efficient, heating costs will be lower than homes built with other systems.

The method’s superior insulation levels offer a huge benefit in terms of space heating – SIPs homes require very little – which means that the system lends itself perfectly to eco-heating systems that have low output temperature.

Standard heating system choices for SIPs homes include heat recovery and air ventilation systems, particularly good for asthma sufferers.

Reduced thermal bridging

Siptec claims a SIP house will give energy savings of 40 – 60 per cent more than a timber-frame house of equal size. Airtight SIP-built houses easily comply with the air-leakage test for all new builds that is part of new building regulations due within 12 months.

“The composite nature of SIPs provides an efficient and effective solution to reducing thermal losses and therefore improving energy conservation,” says Orriss.

“SIPs offer the efficiency of structural and thermal performance within one product. U-values as low as 0.11 W/m2K can be achieved through the use of SIPs whilst also limiting the increase in building dimensions (wall thickness).”

SIP Build UK are based in Yorkshire and are a nationwide designer, manufacturer and installer of the Kingspan TEK SIP system.

SIPs are manufactured under factory-controlled conditions. This offsite fabrication means that your weatherproof building shell can be complete just a few days after the ground works are ready to receive them.

SIP panels are either 142mm or 172mm thick. Typically they are 1220mm wide and can be as long as 7.5 metres in length to suit each individual project.

Read more: Energy Efficient SIP Build System

The resultant homes are draught-free, warm in winter and cool in summer – which drastically reduces energy consumption and carbon dioxide emissions for the lifetime of the building.

“The main benefit of SIPs over other panelised forms of construction is due to the limited quantity of repeating thermal bridges such as studs and noggins. Therefore a typical value of 94 per cent of the panel area is counted as insulation when calculating the U-value of building components,” says Orriss.

What are the disadvantages of building with SIPs?

A potential disadvantage for some is there cannot be any on site changes: the client has to make all the decisions about the self build and sign off the drawings before the build begins.

It is vital that the dimensions of the foundations are accurately measured and constructed, so that the SIPs fit perfectly.

What does the future hold for SIPS?

SIP builds are booming. The government is keen to encourage building with SIPs as it is quick and economical – it uses about 60 per cent less timber than conventional timber-frame construction.

Who are the major manufacturers?

Major manufacturers of SIPs for houses are Siptec, Sip Building Systems (who supply Sipit), Kingspan Tek and Build It Green.

Some manufacturers just supply kits for self builders, some supply and appoint their own regional installers, some offer a design, build and installation service.

There are plenty of companies that design and build homes with SIPs, too. You can explore these in our Structural Systems Directory.

How much does it cost?

For a complete four-bedroom detached house of 200m², Andrew H Wilson, one of Kingspan TEK’s system suppliers, can supply a turnkey option (you don’t have to do anything) for £240,000. This is the equivalent of £1,200 per m². Panels only would be much cheaper.

Today, we will figure out how to ascertain the quantity of the brickwork required. Here Calculation of Brick Work Quantity nitty gritty clarification given underneath. Subsequent to realizing the 1 meter cube volume we can figure the staying quality effectively by simply increasing the 1 meter cube aftereffect of the ideal volume.

1. The width of the wall which is going to be fabricated. 2. Number of the opening in the wall like (Door,Windows,etc) 3. Size or which sort of the brick going to utilize

We should take a guide to see well.

Model: Assume we need to build the wall having a volume of 1 meter cube,the size a brick is going to utilize is 190 mm x 90 mm and mortar is 8 mm thick with a proportion of 1:4. So, we need to find out the following:

1. Quantity of bricks 2. Quantity of cement 3. Quantity of sand

Given information : This calculation can happen into 2 stages.

1. Brick Calculation 2. Mortar Calculation

Step1: Volume of 1 brick

= 0.19 m x 0.09 m x 0.09 m = 0.001539 meter cube

Volume of 1 brick with mortar = 0.198 m x 0.098 m x 0.098 m = 0.0019 meter cube

No of brick in 1 work = volume/volume of bricks with mortar = 1/0.0019 = 526 bricks

Stage 2: Mortar Calculation

Volume canvassed by 526 bricks in 1 cum volume = (Bricks number x volume of 1 brick) = 526 x 0.001539 = 0.81 meter cube

Mortar Volume = (Total volume – volume of bricks) = 1 – 0.81 = 0.19 meter cube(Wet Volume)

Dry Volume = 0.19 x 1.33 = 0.2527 meter cube(dry volume)

Note: 1.33 is a constant

Cement: = (dry volume x Ratio x Density of cement in 1 cum)/Sum of Ratio = (0.2527 x 1 x 1440)/5 = 72.77 kg/50 <1 sack = 50 kg> = 1.5 sacks

Sand: = (dry volume x proportion x 35.3147) / Sum of ratio(1 cum = 35.3147 cubic feet) = (0.2527 x 4 x 35.3147)/5 = 7.1 cubic feet

Results

Bricks = 526 Cement = 1.5 packs Sand = 7.1 cubic feet

Addendum: These proportions may change by changing the component of the mortar thickness or size of the bricks just as the mortar proportions 1:4, 1:6 and so on.

Rate Analysis of brickwork is based on the rates of different types of materials like cement, sand, bricks, and rates for labor i.e. mason, water carrier and other labors. The rates of these differ location wise and time. These are acquired from the schedule of rates of specific location or from local market and should be multiplied with the quantities of materials and labors already calculated to obtain the rate analysis.

For rate analysis of brick masonry, 1m3 of brick masonry is taken into consideration.

1. Number of bricks for 1 cubic meter of brick masonry: For 1m3 of brick masonry, the number of standard size of bricks necessary is 494.

2. Quantity of mortar for 1m3 of brick masonry: For 1m3 of brickwork, the quantity of the mortar necessary is 25 – 30%, i.e. 0.25m3 – 0.3m3 of cement masonry.

Labors necessary for brick masonry are mason for brick work, labors for carriage of materials (sand, cement, bricks, and water), mixing and transporting mortar.

The quantity of labour is stated as requirement of labour in days for 1m3 of brick masonry.

The tutorial focuses on the following points:-

Mortar is applied to retain the various building materials like brick or stone jointly. It is developed with a dense mixture of water, sand, and cement. The role of water is to moisturize the cement and maintain the mix organized. The water to cement ratio is greater in mortar as compared to concrete so that its bonding element can be developed.

Good mortar plays a vital role in all brick or block walls as it ties the units collectively as well as allows to bear the provided weight on the wall and blocks the joints to arrange for a weatherproof wall. It is essential to utilize good materials for developing mortar to get superior result.

Quantity of cement mortar is required for rate analysis of brickwork and plaster or estimation of masonry work for a building or structure. Cement mortar is used in various proportions, i.e. 1:1, 1:2, 1:3, 1:4, 1:6, 1:8 etc.

Rate analysis for cement mortar requires calculation of materials for cement mortar is required for making rate analysis of cement mortar i.e. quantity of cement and sand essential for 1m3 with different ratios like CM 1:2, 1:4, 1:6, 1:8 etc. Therefore, initially the quantity of cement and sand should be calculated for 1m3 of cement mortar.

1.3m3 of cement and sand is necessary for creating 1m3 of wet cement mortar because of existence of voids in sand in dry state. So, cement and sand quantity is computed for 1.3m3 of cement mortar.

Computation of Materials for Cement Mortar - Given below, the detailed phases for estimation of quantity of cement and sand for cement mortar:

Suppose, it is required to estimate quantity of cement and sand for CM 1:X, where, 1 denotes proportion of cement and X denotes proportion of sand. Then, quantity of cement is computed as:

RATE ANALYSIS OF BRICKWORK

RATE ANALYSIS OF BRICKWORK

Assuming:-

 Volume of brickwork = 1m³

Size of brick—>19x9x9 cm

Thickness of mortar = 10mm (1cm)

Quantity of Bricks:-

    No. of bricks = Volume of brickwork/ volume of 1 brick with mortar

Volume of 1 Brick with mortar = 0.20×0.10×0.10=0.002 m³

∴ No. of bricks = 1/0.002 = 500 No’s

Quantity of cement:-

Volume of bricks= (0.19×0.09×0.09) x 500 = 0.001539 x 500 = 0.7695 m³

Quantity of mortar =…
