Reactive powder concrete using bulk coal mining industry solid waste and preparation method thereof
The invention discloses a reactive powder concrete using bulk coal-mining industry solid waste. The reactive powder concrete is prepared by replacing silica fume, fly ash and part of cement with coal-mining industry solid waste treatment materials on the basis of recycling bulk coal-mining industry solid waste, thereby realizing the effects of large-scale absorption and high-valued utilization of solid waste, and reaching the purposes of reducing cost, reducing sand, and realizing energy conservation and emission reduction. In addition, the invention further provides a preparation method of the reactive powder concrete by using bulk coal mine industry solid waste. The method 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 of the obtained concrete can reach 120 MPa, and the highest flexural strength can reach 30 MPa; and the reactive powder 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的活性粉末混凝土，利用煤矿工业固废处理料代替硅灰、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，另外本发明还提供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，该方法制备工艺简单，成本低，材料来源广泛，消纳大宗固废，得到的混凝土的抗压强度最高可达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。
