Admixtures related to moisture control (called water-reducing admixtures) generally consist of additives that allow for concrete to retain its workability given a water content lower than that of typical concrete. Reducing the amount of water in a concrete mix will generally cause an increase in strength; however, in unmodified concrete (no ...
Admixtures can restore loads of concrete that might need to be rejected due to delays or other complications. They can improve the performance of problem concrete by modifying its characteristics and enhancing workability. Admixtures are additions to a concrete mix that can help control the set time and other aspects of fresh concrete.
