How to calculate Quantity of Cement, Sand & water In Mortar of 1:4

How to calculate Quantity of Cement, Sand & water In Mortar of 1:4

Quantity of Mortar:-

Volume of mortar= 1 m³

Mix Ratio –> 1:4

Dry volume of mortar = Wet volume x 1.33

Dry Volume = 1.0 m³ x 1.33 = 1.33 m³

Quantity of cement:-

Quantity of Cement = (Dry Volume of mortar x Cement ratio) / (Sum of the ratio)

∴ Quantity of cement = (1.33 x 1) /(1+4)= 0.266 m³

 Density of Cement = 1440 kg/m³

∴ Weight of Cement = 1440 x 0.266 = 383.04 Kg

1 bag of cement contains 50 kg…

How to calculate quantity of Cement & Sand in plaster?

Calculate quantity of cement, sand and water cement ratio in plaster? Formula for calculation of cement sand quantity for plaster mortar.

Plaster is the major part of building construction & cement mortar is used for plastring, a little irresponsibility in mortar mixture cost you loss of quality, money.

In this post you will learn about estimation of cement & sand in mortar and water cement ratio. Below we will calculate quantity in Cubic feet as in Cubic Meter.

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.

How to calculate Quantity of Cement, Sand & water In Mortar of 1:3

How to calculate Quantity of Cement, Sand & water In Mortar of 1:3

Quantity of Mortar:-

Volume of mortar= 1 m³

Mix Ratio –> 1:6

Dry volume of mortar = Wet volume x 1.33

Dry Volume = 1.0 m³x 1.33 = 1.33 m³

  Quantity of cement:-

Quantity of Cement = (Dry Volume of mortar x Cement ratio) / (Sum of the ratio)

∴Quantity of cement = (1.33 x 1) /(1+3)=0.3325 m³

 Density of Cement = 1440 kg/m³

∴ Weight of Cement = 1440 x 0.3325 = 478.8Kg

1 bag of cement contains 50 kg…

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:
