The strength development of cementitious materials is a well-understood phenomenon. One important factor is chemical reaction, which uses water to react with mineral composition of cement. The enough amount of water used is important to complete the chemical reaction of cementitious materials. In case that the water-cement ratio is very small, a significant amount of water does not sufficiently penetrate from outside and too little amount of water remains inside concret for hydration because concrete grows denser due to the progress of hydration. As a result, the condition of self-desiccation and autogenous shrinkage occur in a specimen. In this research, the effects of penetration of curing water on self-desiccation and strength of cementitious materials are investigated. From these results, it was found that the larger range of self-desiccation occurred in the lower water-cement ratio specimens, and the curing water mixed with AE (The lower surface tension liquid) decreased the degree of self-desiccation and got more strength of the low water-cement ratio specimens.
