AbstractInteractions occur when admixtures in aqueous solutions or in suspensions are added to cement and cement components. Physical adsorption, chemisorption, and chemical reactions generally, occur with the hydrating components. Many physical and chemical changes are influenced when admixtures such as accelerators, retarders, water reducers, superplasticizers, air-entraining agents, and additions such as latexes, and mineral materials are added to the cement- water system. The mechanism of the action of admixtures and additions, and the changes in water demand, viscosity, setting, slump loss, shrinkage, kinetics of hydration, microstructure, strength and durability of fresh and hardened cement can be explained by interaction effects.
