Alkali-activated grouting material and preparation method thereof
The invention discloses an alkali-activated grouting material and a preparation method thereof, and the alkali-activated grouting material comprises the following raw materials in parts by weight: 200-700 parts of a precursor, 50-450 parts of an activator, 10-100 parts of a composite additive and 400-800 parts of aggregate, wherein the precursor is a mixture of slag, steel slag and fly ash in a mass ratio of (1-4): (1-2): (0.5-1). The precursor is selected as the mixture of the slag, the steel slag and the fly ash, so that the grouting material has excellent compression resistance and relatively high fluidity under the synergistic effect of the slag, the steel slag and the fly ash, and can be widely applied to bridge support and foundation grouting.
本发明公开了一种碱激发灌浆料及其制备方法，其中，碱激发灌浆料包括以下重量份的原料：前驱体200～700份、激发剂50～450份、复合外加剂10～100份、骨料400～800份；其中，前驱体为矿渣、钢渣和粉煤灰按质量比为1～4：1～2：0.5～1的混合物。本发明通过将前驱体选为矿渣、钢渣和粉煤灰的混合物，能够使灌浆料在矿渣、钢渣和粉煤灰的协同作用下，具有优异的抗压性能和较高的流动性，可被广泛应用于桥梁支座和基础灌浆中。
