Advantages of Incorporating Supplementary Cementitious Materials (SCMs) in Concrete

As the construction industry seeks more sustainable and high-performance solutions, the use of Supplementary Cementitious Materials (SCMs) has emerged as a game-changer. SCMs, which include ground granulated blast furnace slag (GGBS), Fly Ash, and silica fumes, are increasingly being used to enhance the durability and performance of modern concrete mixes while promoting environmental sustainability. In this article, we will explore the benefits of SCMs and their role in modern construction practices.

Understanding Supplementary Cementitious Materials (SCMs)

SCMs refer to materials derived from industrial byproducts or natural processes that can be added to concrete to improve its properties. At Firstchoice Ready Mix, we highly recommend using SCMs due to their ability to enhance the strength, workability, and durability of concrete. SCMs typically contain compounds such as silica, alumina, and calcium, which react with cement hydration products to form calcium silicate hydrate. This reaction improves the overall structure and strength of concrete, making SCMs a popular choice in modern construction.

By incorporating SCMs, construction companies can reduce their reliance on traditional Portland cement, which is energy-intensive and contributes significantly to carbon emissions. SCMs offer a sustainable alternative that supports environmental goals while enhancing the performance of concrete.

Key Benefits of SCMs in Concrete

 1. Ground Granulated Blast Furnace Slag (GGBS)

GGBS is a byproduct of the steel and iron industries, produced by cooling molten iron slag. It is an essential SCM that improves the durability and workability of concrete. At Firstchoice Ready Mix, we use GGBS to create high-strength cement, which is resistant to surface attacks, chloride penetration, and other environmental factors.

GGBS is especially beneficial in harsh conditions, such as marine structures and wastewater treatment plants, where durability is crucial. Additionally, using GGBS reduces the carbon footprint of concrete by minimizing the energy required for cement production, making it an eco-friendly choice.

 2. Fly Ash

Fly Ash, produced from coal combustion, is another widely used SCM that enhances concrete properties. It contains silica, alumina, and iron oxide, which contribute to pozzolanic reactions in concrete. Fly Ash improves the workability and pumpability of concrete, making it easier to handle during construction.

At Firstchoice Ready Mix, Fly Ash is used in large-scale projects to produce high-strength concrete mixes.

Importance of Curing Concrete

Proper curing of concrete is essential for developing its desired properties, particularly compressive strength. At First Choice Ready Mix, we adhere to stringent standards to ensure adequate curing time, achieving optimal results. Concrete that is properly cured continues to hydrate and gain strength, which is crucial for the longevity and durability of any structure. If curing is not properly done, the concrete may fail to achieve its intended strength, leading to potential structural weaknesses.

Curing also plays a significant role in managing the heat of hydration, an exothermic process that occurs when water and cement mix. At First Choice Ready Mix, we control the heat of hydration to prevent thermal cracking during the initial stages of curing. Proper curing involves controlling temperature increases and maintaining an appropriate water-cement ratio, which helps ensure the concrete's resistance and prevents the risks of thermal cracking. Inadequate curing can lead to improper hydration of the cement, resulting in reduced strength gain and increased risk of shrinkage cracks.

Preventing the evaporation of water from the concrete surface is crucial for ensuring adequate curing. At First Choice Ready Mix, we allocate significant time for curing, allowing the surface to retain adequate moisture within the concrete. This prevents rapid evaporation of water, enabling the surface to continue the hydration process uniformly. Proper curing is essential for high-strength concrete mixes, as it helps prevent drying shrinkage and cracking. Conversely, inappropriate curing can lead to rapid water evaporation and structural weaknesses.

Modern construction requires durable concrete with low porosity, achieved through adequate curing. Proper curing increases the durability of concrete by reducing its permeability, preventing seepage and efflorescence. Conversely, improper curing can decrease the concrete's durability by increasing its porosity, leading to reduced permeability and potential structural issues.

Methods of Concrete Curing

Water Ponding

Water ponding is an effective method for ensuring complete curing of concrete. It involves covering the concrete surface with water to keep it continuously wet, maintaining adequate moisture content. This method is particularly suitable for flat surfaces such as slabs. However, it requires consistent water supply and can be labor-intensive.

Gunny Bags

Gunny bags, also known as burlap, are commonly used to cover the concrete surface, keeping it continuously wet. This method is cost-effective and suitable for vertical surfaces and columns. Gunny bags help retain moisture, keeping the concrete fully hydrated and preventing shrinkage or cracking.

Curing Compounds

Curing compounds are chemical substances that form a moisture-retaining film on the concrete surface. They prevent water leakage and promote hydration, making them suitable for large areas where water curing methods may be impractical. At First Choice Ready Mix, we recommend curing compounds for large-scale projects to ensure adequate surface treatment.

Plastic Sheeting

Covering the concrete surface with plastic sheeting is another effective curing method. It helps maintain moisture within the surface, especially in high evaporation rates. Plastic sheeting is beneficial for maintaining hydration and preventing rapid water loss.

Steam Curing

Steam curing accelerates the hydration process, increasing the strength of concrete structures. Controlled and efficient use of steam can yield significant results in large-scale production. This method is particularly useful for projects requiring rapid strength gain.
