Other materials incorporated into a special design mix are collectively called admixtures and may include entrained air, water reducers, retarders and accelerators. The water/concrete ratio is another important factor to consider when designing a concrete mix.

Depending on the conditions the concrete is exposed to the desired set time for the concrete, required strength, placeability and finishability, and even the desired color, different admixtures or pozzolans can be added. Entrained air is vital for concrete exposed to road salts, for example, whereas cement slag or metakaolin can lighten the color of concrete in order to make its integral color pop.

In short, pozzolans and admixtures allow you to create a fully customized ready mix for your building or decorative project. Consult with us for more information on the design mix options available at TexCon’s ready mix plants.
