In the simulation of mineral-like materials, the most used materials are granular soil, in which iron is usually adopted as a kind of aggregate for increasing bulk density.
在矿山相似材料模拟中，相似材料大多数为散粒体，而铁作为一种增加容重的骨料在其中得到广泛的应用。

Concretes of C30 and C60 were prepared with iron mine tailings as fine aggregate and coarse aggregate and with natural sand and common crushed stone separately.
分别以铁尾矿砂和铁尾矿石代替天然砂和普通碎石配制了C30和C60两个强度等级的混凝土。
