Abstract:

Water Reducing Admixtures (WRAs), sometimes referred to as plasticizers, are designed to free trapped water that is present in concrete mixtures and are used in a variety of applications to ensure or improve workability. When cement clinker is ground, electrical charges are created on the surface of the particles. During concrete mixing, cement particles bond together and trap water. The WRA breaks the bond and frees the trapped water which is then available to aid workability and increase cement hydration.
