FINE AGGREGATE, AND METHOD FOR PRODUCING AGGREGATE
PROBLEM TO BE SOLVED: To provide a fine aggregate usable as the raw material for a cement hardened body even if a water absorption percentage is relatively high, and further, to provide a method for producing the fine aggregate.SOLUTION: Provided is a fine aggregate forming a cement hardened body by being kneaded with cement and water, in which a water absorption percentage is 2% or more, the ratio with a grain size of 0.15 mm or lower is 0 mass%, the ratio with a grain size above 0.15 to 0.6 mm is 40 mass% or lower, and the ratio with a grain size above 5 mm is 0 mass%.SELECTED DRAWING: None
【課題】吸水率の比較的高くてもセメント硬化体の原料として使用することができる細骨材を提供すると共に、該細骨材の製造方法を提供することを課題とする。【解決手段】セメント及び水と共に混練されてセメント硬化体を形成する細骨材であって、吸水率が２％以上であり、０．１５ｍｍ以下の粒径が０質量％、０．１５ｍｍを超えて０．６ｍｍ以下の粒径が４０質量％以下、５ｍｍを超える粒径が０質量％であることを特徴とする。【選択図】なし
