It has been suggested that drying shrinkage of hardened cement paste, mortar and concrete is strongly related to mix proportion. The purpose of this experiment is to examine past theories about the relation between mix proportion and drying shrinkage, using many specimens made with various mix proportions. The relations of factors of mix proportion, such as water content in the original mix, to drying shrinkage already pointed out by many investigations were also observed in this experiment over a comparatively wide range of mix proportion, except for lean mixture of extremely stiff consistency. These relations can be systematically explained by the theoretical law of drying shrinkage derived from multiphase approach. It is expected that the law can properly predict the effect of mix proportion on drying shrinkage of concrete.
