Self-Curing Concrete

Abstract

Self-curing concrete is achieved by means of replacing a part of aggregate by lightweight aggregate or adding chemical admixtures. The self-curing process of concrete takes place from inside to outside, thus reducing the autogenous shrinkage and self-desiccation, especially for the high-performance concrete with relatively low water/binder ratio. The durability and the workability of self-curing concrete are improved, compared with conventional air-cured concrete, while the mechanical properties may be either enhanced or compromised due to the dual function of self-curing agent. Self-curing concrete has been widely applied in actual practice, mostly bridge decks and pavements. Keywords
