The early age properties and the relation between hydration heat and autogenous shrinkage of high-strength concrete were investigated. In the results, most autogenous shrinkage of high-strength concrete occurred in a few days after casting. The shape of autogenous shrinkage history corresponded well to the shape of hydration temperature history at early ages. There was a close relation between hydration heat and autogenous shrinkage at early ages, especially between hydration heating velocity (HHV) and autogenous shrinking velocity (ASV). And it is noted that HHV can affect the ultimate autogenous shrinkage.
