Method for preparing reactive powder concrete by using bulk coal mining industry solid waste
The invention discloses a method for preparing reactive powder concrete by using bulk coal mining industry solid waste, which is characterized in that coal gangue and coal indirect liquefaction ash are used for replacing silica fume, fly ash and part of cement, and the reactive powder concrete is prepared on the basis of recycling bulk coal mining industry solid waste. The effect of combining large-scale absorption and high-value utilization of the solid waste is achieved, and the purposes of reducing the manufacturing cost, reducing gravel, saving energy and reducing emission are achieved. The prepared concrete is simple in preparation process, low in cost, wide in material source and capable of absorbing a large amount of solid waste, the highest compressive strength can reach 120 MPa, the highest breaking strength can reach 30 MPa, and the concrete has wide application in the fields of civil engineering building materials and decorative materials.
本发明公开了一种利用大宗煤矿工业固废制备活性粉末混凝土的方法，其特点是利用煤矸石、煤间接液化灰渣代替硅灰、粉煤灰和部分水泥，在大宗煤矿工业固废再利用的基础上制备活性粉末混凝土，实现固废规模化消纳与高值化利用兼备的效果，达到了降低造价，减少砂石，节能减排的目的。本发明所制得的混凝土制备工艺简单，成本低，材料来源广泛，大宗固废消纳，抗压强度最高可达120MPa，抗折强度最高可达30MPa，在土木工程建材及装饰材料领域具有广泛用途。
