摘要
选取两种高硅铁尾矿,针对各自特点,进行了以尾矿为主要原料制备高强混凝土材料的实验研究;实验结果表明,此两种高硅型铁尾矿制备出的试块抗压强度均可达到100MPa以上,尾矿用量达70%,提高了尾矿的综合利用率。
Select two kinds of high-silicon iron tailings as the main raw materials,according to their characteristics,experimental study of high-strength concrete was conducted.Experiments show that the compressive strength of samples produced by the two high-silicon iron tailings can reach more than 100MPa,respectively.With 70% content of tailings,this way increases the comprehensive utilization of tailings.
