 note = {The main objective of this study is to clarify the influence of limestone aggregate on strength and drying shrinkage of concrete. Three kinds of limestone aggregates from different regions of Japan were used. The specimens were mixed with fine or coarse limestone and sandstone. As a result, the strengths and modulus of elasticity of concretes with limestone were larger than those of sandstone concretes. The drying shrinkage of concrete with fine or coarse limestone aggregate decreased clearly regardless of the region of production. Furthermore, the volume change of limestone aggregate in water and drying condition was quite smaller than that of sandstone aggregate. It is thought that the main cause of the reduction of drying shrinkage in concretes with limestone is the volume change of the aggregate itself.},
