This paper deals with the influence of aggregate properties on concrete drying shrinkage. Drying shrinkages of concretes with various types of aggregates were measured and relationships between the fundamental properties of aggregates and the shrinkage strains of concretes were investigated. Furthermore, specific surface areas (S.S.A.) of aggregates were measured by moisture sorption isotherm tests up to 32.5%R.H. Drying shrinkages of concretes with various kinds of aggregates increased with the increase of the S.S.A.s of aggregates. The test results indicated that the S.S.A. will be an effective index for evaluating the influence of aggregate on the drying shrinkage of concrete.
