STEEL FIBER-REINFORCED CONCRETE
To provide steel fiber-reinforced concrete with higher dispersibility of steel fibers, excellent compression strength, flexure strength and flexure toughness.SOLUTION: Steel fiber-reinforced concrete comprises cement, water, coarse aggregate, fine aggregate, chemical admixture and steel fiber and the dispersion ratio of the steel fiber defined by the following formula (1) is equal to or greater than 60%. (where, in the formula (1), FD is the dispersion ratio (%) of the steel fiber, VD is the mass (g) of the steel fiber not bound and VA is the mass (g) of the entire steel fiber (the total of the bundle of the steel fiber and the steel fiber not bound).SELECTED DRAWING: None
【課題】鋼繊維の分散性が高く、圧縮強度、曲げ強度および曲げタフネスに優れる鋼繊維補強コンクリートを提供する。【解決手段】セメントと、水と、粗骨材と、細骨材と、化学混和剤と、鋼繊維と、を含み、下記の式（１）で定義される前記鋼繊維の分散率が６０％以上である、鋼繊維補強コンクリート。［数１］TIFF2023034150000008.tif18170（但し、式（１）において、ＦＤは鋼繊維の分散率（%）、ＶＤは束になっていない鋼繊維の質量（ｇ）、ＶＡは全体の鋼繊維（鋼繊維の束および束になっていない鋼繊維の合計）の質量（ｇ）である。）【選択図】なし
