Metallurgical waste residue-based filling cementing material and preparation method thereof
The invention relates to the field of underground filling, and particularly discloses a metallurgical waste residue-based filling cementing material and a preparation method thereof, and the metallurgical waste residue-based filling cementing material is prepared from the following raw materials in percentage by mass: 2-3% of coconut tree carbon powder ash, 12-13% of fly ash, 20-30% of blast furnace slag, 40-50% of cement clinker, 9-10% of rubber and the balance of water. And establishing a performance influence model of the cementing material based on the coconut tree carbon powder ash and the coal ash. The blast furnace slag is activated by using the metallurgical waste residue activating agent, the utilization rate of blast furnace slag active ingredients in the cementing material can be increased, the coconut tree carbon powder ash is added to replace fly ash with the corresponding mass so as to be better combined with the blast furnace slag, the cementing speed is higher, and the hardness of the hardened cementing material can be improved. In addition, phosphate gel is added in the preparation of the gel material, so that the alkalinity and acid corrosion resistance of the underground filler are improved.
本发明涉及井下充填领域，具体公开了一种冶金废渣基充填胶凝材料及其制备方法，由以下原料制成，按质量百分比计：椰树碳粉灰2‑3％份，粉煤灰12‑13％，高炉渣20‑30％，水泥熟料40‑50％，橡胶9‑10％，其余为水；建立了基于椰树碳粉灰和粉煤灰对胶凝材料的性能影响模型。本发明通过使用冶金废渣活化剂对高炉渣进行活性处理，能够提高胶凝材料中高炉渣活性成分的利用率，并且，通过加入椰树碳粉灰替代相应质量的粉煤灰以与高炉渣更好的结合，更快的胶凝速度，且能够提高凝胶材料硬化后的硬度。此外，在凝胶材料的制备中添加磷酸盐凝胶，提高井下充填物的碱度和耐酸腐蚀性。
