Abstract:The hydration and factors relating to the durability of hardened cement paste and concrete have been investigated. Both chemical and physical factors involved in the paste and concrete microstructure are governing factors in prediction of performance. This paper addresses the effects of cementitious materials modified by the presence of granulated blast furnace slag, fly ash, or silica fume. Special alkali-activated cements are also discussed. Initial structure developed in the fresh state is transmitted to the final structure, including the paste pore structure, and is important in resisting forces of degradation. Considerable advances have been made in understanding the mechanisms of degradation, such as shrinkage, freezing, and thawing, carbonation, intrusion of undesirable chemicals, or leaching of species to the environment.
