Abstract

This study discusses the properties of shrinkage of high performance concrete with W/B and water content. According to results, drying shrinkage decrease of water content due to the influence of autogenous shrinkage. And drying shrinkage is reduced with a decrease of water content. As W/B decreases, autogenous shrinkage increases because shrinkage by hydration is generated greatly due to an increase of binder content. Also, as water content decreases, it is reduced because of a decrease of cement paste by cement content.
