Steel slag-based alkali-activated cementing material as well as preparation method and application thereof
The invention discloses a steel slag-based alkali-activated cementing material as well as a preparation method and application thereof. The steel slag-based alkali-activated cementing material comprises solid powder and water. The solid powder comprises the following components in percentage by mass: 40-60 wt% of ground steel slag powder, 0.5-1 wt% of ground aluminum ash slag powder, 15-20 wt% of coal ash, 10-15 wt% of slag powder, 5-10 wt% of silica fume and 1-5 wt% of a solid activator. According to the steel slag-based alkali-activated cementing material, the ground steel slag powder can be utilized on a large scale, so the problems of environmental pollution and farmland occupation caused by steel slag stacking or landfill in the prior art are effectively relieved; and meanwhile, material cost can be reduced when the material is applied to low-strength concrete or mine filling.
本发明公开一种钢渣基碱激发胶凝材料、制备方法及其应用。所述钢渣基碱激发胶凝材料包括固体粉料和水；按质量百分数计，所述固体粉料包括以下组分：磨细钢渣粉40～60wt%；磨细铝灰渣粉0.5～1wt%；粉煤灰15～20wt%；矿渣粉10～15wt%；硅灰5～10wt%；固体激发剂1～5wt%。上述钢渣基碱激发胶凝材料可以将磨细钢渣粉进行规模化利用，进而有效缓解现有钢渣堆放或填埋造成的环境污染以及占用农田的问题；同时将其应用于低强度混凝土或矿井填充中，可降低原料成本。
