COMPOSITION CONTAINING AGGREGATE, BINDER, AND WATER
The present invention aims at providing a composition containing aggregate, binder, and water that can achieve a higher degree of both flowability in the fresh state and a limitation of autogenous shrinkage. A composition of the present invention contains binder, aggregate, and water, wherein the aggregate contains: small-diameter aggregate classified into particle diameters of 300 µm or more and less than 1.18 mm; medium-diameter aggregate classified into particle diameters of 1.18 mm or more and less than 4.75 mm; and large-diameter aggregate classified into particle diameters of 4.75 mm or more and 5mm or less; wherein a ratio of volume of water to a sum of volume of the binder and volume of aggregate having particle diameters of 5 mm or less is 15% or more and 26% or less, and the small-diameter aggregate, the medium-diameter aggregate, and the large-diameter aggregate each have a BET specific surface area of 0.4 (m2/g) or less.
