CLINKER AGGREGATE, AND CEMENT CONCRETE PREPARED THEREWITH
PROBLEM TO BE SOLVED: To provide a clinker aggregate that imparts excellent fluidity to cement concrete, has high bending strength, and is resistant to the permeation of chloride ions, and cement concrete prepared therewith.SOLUTION: A clinker aggregate has a fineness modulus of 2.0-3.5, a content of particles of 0.15 mm or less of 10% or less, a content of CaO components of 15-40 mass%, and a content of AlOcomponents of 55-75 mass%. The clinker aggregate preferably has a porosity of 10 vol.% or less. There is also provided cement concrete prepared with the clinker aggregate.SELECTED DRAWING: None
