What is high early concrete?

High early concrete is a special type of concrete that increases its strength significantly in the first 24 hours after it’s poured. This is accomplished by using an accelerating admixture that increases the rate of hydration of cement. high early concrete is great for winter climates as it sets quicker and also allows you to build your project more quickly than a standard concrete mix.

In addition to reducing construction times, high early concrete offers a smooth surface that reduces the need for grinding which saves you even more time. This type of concrete isn’t suitable for every project, however, as it can be prone to cracking and shrinkage. It’s important to speak with your concrete supplier before using this type of concrete for your project so they can help you decide if it’s the right fit.

Using high-early strength concrete requires a little more attention to the mix design process and curing conditions than a regular concrete mix. The mix should have a slump flow of about 4 to 6 inches, a cement ratio of 0.40 to 0.50, and use ground granulated blast furnace slag (or another supplementary cementitious material).

This type of concrete is also more sensitive to changes in temperature. For this reason, it’s important to store it properly and keep the temperature as close to room temperature as possible. Also, some concrete companies charge a short load fee for deliveries that aren’t full loads of concrete, so be sure to check with your concrete company before ordering.
