Steel slag composite grouting material and preparation method thereof
The invention provides a steel slag composite grouting material and a preparation method thereof, and relates to the technical field of grouting materials. The steel slag composite grouting material comprises the following raw materials in parts by weight: 40-70 parts of steel slag, 20-35 parts of cement, 20-30 parts of quartz sand, 20-30 parts of fly ash, 10-20 parts of bentonite, 10-25 parts of gypsum powder, 5-8 parts of fibers, 5-10 parts of an alkali activator, 2-6 parts of a water reducing agent, 1-5 parts of a defoaming agent, 1-3 parts of a penetrant, 1-3 parts of a leveling agent and 2-5 parts of an anti-aging agent. The preparation method comprises the following steps: weighing the steel slag, the cement, the quartz sand, the fly ash, the bentonite, the gypsum powder, the fiber and the alkali activator according to the weight, and uniformly conducting mixing to obtain a mixture; uniformly mixing the mixture with the water reducing agent, the defoaming agent, the penetrating agent, the levelling agent and the anti-aging agent to obtain the steel slag composite grouting material. The obtained grouting material has the advantages of high compressive strength, good curing effect in a short time, low dry shrinkage rate and the like.
本发明提出了一种钢渣复合灌浆料及其制备方法，涉及灌浆材料技术领域。一种钢渣复合灌浆料，包括以下重量份的原料：钢渣40～70份、水泥20～35份、石英砂20～30份、粉煤灰20～30份、膨润土10～20份、石膏粉10～25份、纤维5～8份、碱激发剂5～10份、减水剂2～6份、消泡剂1～5份、渗透剂1～3份、流平剂1～3份和抗老化剂2～5份。制备方法为：按量称取钢渣、水泥、石英砂、粉煤灰、膨润土、石膏粉、纤维和碱激发剂，混合均匀得到混合料；将混合料与减水剂、消泡剂、渗透剂、流平剂和抗老化剂混合，混合均匀得到所述钢渣复合灌浆料。本发明得到的灌浆料具有抗压强度高、短时间内固化效果好和干缩率低等优点。
