ROLLING CONCRETE PAVEMENT MATERIAL
PROBLEM TO BE SOLVED: To provide a rolling concrete pavement material mainly containing a blast furnace slag which is a by-product in a steel mill.SOLUTION: In manufacturing a rolling concrete pavement material by blending a coarse aggregate, a fine aggregate, cement and water, the coarse aggregate is a blast furnace slag having water absorption percentage of 1% or less, absolute volume percentage of 60% or more and preferably percentage of wear of 20% or less.SELECTED DRAWING: Figure 1
【課題】 製鉄所における副産物である高炉スラグを主成分とした転圧コンクリート舗装材を提供する。【解決手段】 粗骨材、細骨材、セメントおよび水を配合して転圧コンクリート舗装材とするに際し、前記粗骨材を、吸水率：1％以下かつ実積率：60％以上、好ましくはすり減り減量：20％以下の高炉スラグとする。【選択図】図１
