1) Ferrous mill tailings
铁尾矿砂
1.
The ferrous mill tailings are byproducts of mining industry and can be considered as Manufactured Fine Aggregates(MFA).
铁尾矿砂的集料性质决定了铁尾矿砂混凝土易于泌水的特点,用包括硅质石粉在内的矿物掺合料来控制水粉比,按最佳水粉比结合适当减少高效减水剂掺量对配合比进行优化,可有效控制混凝土泌水,并能获得良好的工作性。
2.
On the basis of investigation on properties of ferrous mill tailings,the workability and strength of concretes were researched by substituting ferrous mill tailings for natural sand and/or crashed stone,and the mix proportion was optimized by means of mineral admixtures.
在研究铁尾矿基本性质的基础上,利用铁尾矿砂完全取代天然砂,研究铁尾矿砂混凝土的工作性与强度特点,利用矿物掺合料等手段对铁矿尾砂混凝土配合比进行优化。
