Abstract

In this study, W/B that affect the strength and shrinkage were 4 level(14.5~11.5%), so that the and the physical and shrinkage properties were verified. And the shrinkage formula is suggested at the age of 91. The results showed that the strength of W/B 12.5% was the highest strength. And as W/B decreased, the shrinkage ratio increased. The autogenous shrinkage was rapidly decreased after 28 days.
