When should I use high early strength cement?

When there is a need to increase the compressive strength of concrete, it can be achieved by changing the cement mix design. Often this involves increasing the cement content and using an accelerator, such as calcium chloride, or water-reducing admixture.

Normally, concrete is a mixture of water, cement and aggregates that includes sand, gravel and stone. These are mixed together to form a paste, which is then placed in the formwork.

The amount of water and the type of aggregate used in a concrete mixture affects the concrete’s strength. A higher amount of water means that more hydration takes place, which can lead to a higher compressive strength.

A concrete’s compressive strength is measured in pounds per square inch (psi). Stronger concretes are typically more expensive, but they last longer.

If you’re looking for a stronger and more durable concrete, consider our professional-grade 5000 Plus. It’s 20% stronger than standard concrete and combines high strength with superior workability.

HE Cement can also be used to achieve greater durability and resistance to shrinkage cracking, as it has a lower water/cement ratio than conventional concrete.

It is important to understand how the curing temperature of a material affects its mechanical strength development. For example, when the curing temperature is below 20 degC, the hydration heat is reduced and the compressive strength is retarded. However, when the curing temperature is above 23 degC, the compressive strength of cementitious materials increases dramatically. Hence, it is essential to investigate the effect of early strength accelerators on cement hydration at higher curing temperatures.
