Copper tailing powder reactive powder concrete and preparation method thereof
The invention belongs to the field of application of industrial solid waste in high-performance concrete and application of road and bridge structures, and particularly relates to a copper tailing powder reactive powder concrete and a preparation method thereof. The copper tailing powder reactive powder concrete is prepared from, by weight, 100 to 120 parts of cement, 25 to 35 parts of silica fume, 16 to 22 parts of steel fiber, 107 to 135 parts of quartz sand, 50 to 75 parts of copper tailings, 18 to 26 parts of water and 1 to 3 parts of an efficient water reducing agent. The content of harmful substances in the copper tailings is extremely low, the mineral components are mostly granular and can be closely packed, the compactness of the RPC is effectively improved, and the mechanical property of the RPC is improved. The copper tailing powder reactive powder concrete has considerable compressive strength and flexural strength, can be used for engineering structures such as concrete sound barrier unit plates, road curbs and anti-collision walls, and is convenient to construct and low in cost.
本发明专利属于工业固废在高性能混凝土应用以及道路桥梁结构应用领域，主尤其涉及一种铜尾渣粉活性粉末混凝土及制备方法。一种铜尾渣粉活性粉末混凝土，包括以下重量份原料：水泥100~120份，硅灰25~35份，钢纤维16~22份，石英砂107~135份，铜尾渣50~75份，水18~26份，高效减水剂1~3份。本发明专利的铜尾渣成分有害物质含量极低，且矿物成分形状多为粒状，可以进行紧密堆积，有效提高RPC的密实度，改善其力学性能。本发明专利的铜尾渣粉活性粉末混凝土抗压强度、抗折强度十分可观，且可用于混凝土声屏障单元板、公路路缘石和防撞墙等工程结构，施工便利且成本低。
