Description

In this study, considered coarse aggregate and mix proportion affect drying shrinkage of concrete, young's modulus of coarse aggregate and mix proportion was verified the effect of drying shrinkage. Young's modulus of coarse aggregate was estimated by Hashin-Hansen equation. It was estimated from young's modulus of basis material for young's modulus of another material. Mix proportion of concrete was verified effect of different coarse aggregate. In this verification, relationship between coarse aggregate and effect of r1 were correlated. The coefficient effect of r1 was proved to correct in the young's modulus of coarse aggregate.
