Recently, shrinkage cracking in high-strength concrete caused by autogenous shrinkage and drying shrinkage becomes a major problem. Most of past researches on shrinkage behavior have been conducted under limited conditions of temperature and humidity, and especially the research under different temperatures is very scarce. In this research, three different temperatures and relative humidity were chosen, and the shrinkage behaviors for high-strength concrete and normal-strength concrete under these conditions were measured. Additionally, the mass change and dynamic modulus of elasticity at different ages were measured from these specimens. The research revealed that the shrinkage behavior of concrete greatly depends on the ambient temperature and relative humidity. Further it was recognized that the shrinkage behavior is closely related to degree of hydration, behavior of water evaporation from cement paste, and micro-cracking caused by rapid drying.
