摘要： A concrete composition which has superior fluidity and filling property and from which a concrete structure having high quality and durability and being excellent in resistance to freezing and thawing can be made without compaction by vibration. The composition comprises cement, water, aggregate, at least one admixture selected from the group consisting of a water reducing agent, an air entraining agent, an air entraining water reducing agent and a superplasticizer, and at least one viscosity improver of a cellulose type of viscosity improver having a low foaming property which shows specific viscosity and an acrylic type of viscosity improver having a low viscosity which shows specific viscosity in a specified amount.
