Metallurgical slag-based inorganic cementing material as well as preparation method and application thereof
The invention relates to a metallurgical slag-based inorganic cementing material which comprises steel slag powder, blast furnace slag powder, fly ash, a first excitation material and a second excitation material. The ratio of the excitation material in the cementing material is less than or equal to 25%, so that the maximum utilization of solid wastes can be realized, and the overall cost is low. The gelling system provided by the invention is relatively good in volume stability. The problems that in a traditional gelling system, the utilization rate of steel slag is low, free calcium oxide and magnesium oxide expand and are uneven in distribution, and consequently the gelling system is concentrated in stress and uneven in material performance are solved.
本发明涉及供一种冶金渣基无机胶凝材料，包括钢渣粉、高炉矿渣粉、粉煤灰、第一激发材料和第二激发材料。所述胶凝材料中激发材料占比≤25％，可实现固体废弃物最大化利用，整体成本低。本发明的胶凝体系体积稳定性较好。克服传统胶凝体系中钢渣利用率低，游离氧化钙和氧化镁产生膨胀，分布不均一，导致胶凝体系应力集中，材料性能不均一等问题。
