To increase the pumpability of concrete, any additive that makes the material more workable is beneficial. To increase concrete pumpability, a variety of chemical admixtures have been used, including air-entraining admixture, high-range water-reducing admixture, and finely divided admixture. The properties of the combination determine which kind of chemical admixture to use in concrete and how […]
