CIVIL ENGINEERING MATERIAL AND MANUFACTURING METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a civil engineering material and a manufacturing method thereof of using steel slag for expanding use.SOLUTION: A roadbed paving material 100 being a civil engineering material of using steel slag 10 is formed by mixing powdery slag 11 formed of the steel slag 10 and occupying 95 mass% or more in a rate of 450 μm or less in a particle diameter, sandy slag 12 formed of the steel slag 10 and having a particle diameter falling within a range of 0-5 mm and massive slag 14 being a massive aggregate having a particle diameter of 40 mm or less. At this time, the powdery slag 11, the sandy slag 12 and the massive slag 14 are respectively mixed at a blending rate of 8-21 mass%, 30-60 mass% and 28-56 mass%.
【課題】用途の拡大を図る製鋼スラグを用いた土木材料及びその製造方法を提供する。【解決手段】製鋼スラグ１０を用いた土木材料である路盤舗装材１００は、製鋼スラグ１０から生成され且つ粒径４５０μｍ以下の割合が９５質量％以上を占める粉状スラグ１１と、製鋼スラグ１０から生成され且つ粒径が０〜５ｍｍの範囲内にある砂状スラグ１２と、粒径が４０ｍｍ以下の塊状骨材である塊状スラグ１４とを混合して生成される。このとき、粉状スラグ１１、砂状スラグ１２及び塊状スラグ１４がそれぞれ、８〜２１質量％、３０〜６０質量％及び２８〜５６質量％の配合割合で混合される。【選択図】図２
