Alkali-activated slag-based cement mixture grouting material and preparation method thereof
The invention relates to an alkali-activated slag-based cement mixture grouting material and a preparation method thereof. The alkali-activated slag-based cement mixture grouting material is preparedfrom the following raw materials: Portland cement, water glass, slag and water. The grouting material is prepared from Portland cement, water glass and slag as mixed main materials according to a specific ratio, and has the advantages of good fluidity, controllable setting time, high stone rate, economy, environmental protection and the like, and the proportion of the slag in slurry has obvious influence on the performance of the grouting material; specifically, the higher the slag content is, the smaller the unconfined compressive strength of the slurry is, the smaller the fluidity is, the longer the initial setting time and the final setting time are, and the higher the stone forming rate is; in addition, the industrial waste residues are adopted, good recycling is achieved, and great significance is achieved for environmental protection.
本发明涉及一种碱激发矿渣基水泥混合物灌浆材料及其制备方法，包括如下原料制成：硅酸盐水泥、水玻璃、矿渣和水。本发明制备的灌浆材料采用硅酸盐水泥、水玻璃、矿渣作为混合主体材料，各原料经过特定的配比制成，具有流动性好，凝结时间可控，结石率高，经济环保等优点，矿渣在浆体中的占比对灌浆材料的性能影响明显，具体表现为：矿渣含量越大，浆体无侧限抗压强度越小，流动度越小、初终凝时间越大，结石率越大，本发明中采用工业废渣，具有良好的循环再利用，对于环境的保护具有极大的意义。
