INTERACTIONS OF POLYMERS AND ORGANIC ADMIXTURES ON PORTLAND CEMENT HYDRATION
Interaction of polymers and other organic admixtures on portland cement hydration is reviewed. This has been compiled in a systematic way. First hydration of portland cement is described in short. Later, interaction with 4 important components of portland cement is discussed. Finally interphase effects in polymer modified hydraulic cement are discussed. It is concluded that polymers and organic admixtures interact with the components of portland cement when they come in contact with water. This interaction is due to ionic bonding, causing cross-links which inhibit the film formation property of polymers and influence considerably the crystallization process during the hardening of concrete. Some low molecular weight organic substances also have a considerable influence on portland cement during its reaction with water. (Author/TRRL)
