high early concrete possesses higher compressive strength than standard concrete at the earliest stages of curing. It is used in a wide range of applications, such as rapid form reuse, precast concrete for fast production of elements, high-speed cast-in-place construction, cold weather construction and quick repair of pavements to reduce traffic downtime.
The high early strength properties of this material are attributed to the use of accelerated chemical admixture. This admixture accelerates the hydration degree of concrete and promotes the development of early strength.
This type of admixture is often used in self-consolidating concrete because it eliminates the need for air bubble release during the drying process. It also enables the mixture to dry more quickly, resulting in denser and workable concrete that is easier to handle.
Accelerating chemical admixture can be added to ordinary concrete at any stage of the curing process, but is especially effective when it is combined with a low water/cement ratio and a water-reducing admixture. Typically, these ingredients are mixed together in a bag or bulk silo and delivered to the jobsite.
When estimating how much concrete you need, consider how much area the structure will cover and how deep it will be. Then, enter the dimensions into our concrete calculator and you’ll find out how many cubic yards you need and what the estimated delivery cost is.
