AbstractPhysical adsorption, chemisorption and chemical reactions may occur between the admixtures and the hydrating components of cements. Physical and chemical changes occur when admixtures such as accelerators, retarders, water reducers, and superplasticizers are added to the cement - water system. Mechanisms of the action of admixtures, changes in water demand, viscosity, setting, slump loss, shrinkage, kinetics of hydration, microstructure, strength and durability of fresh and hardened cement pastes can be explained by the interaction effects.
