초록

The purpose of this study is to investigate the shrinkage properties of high strength concrete according to the S/A ratio at early age. The main parameters are as follows : S/A ratio is 30, 35, 38, 41, 45%, W/B ratio 24.9%, SF/B ratio 8%. FA/B 15%. The size of specimen is l0$\times$10$\times$40cm and the shrinkage is measured by the embedded gage at each end of the specimens. From the test, it was found that the slump-flow of concrete was high, and also autogenous shrinkage increased and drying shrinkage decreased as S/A ratio increased.
