Alkali-activated cementing material doped with steel slag and blast furnace slag
The invention belongs to the field of alkali-activated inorganic nonmetal cementing materials, and particularly relates to an alkali-activated cementing material doped with steel slag and blast furnace slag, the material is prepared from the following raw materials in parts by mass: 30-50 parts of steel slag; 15-20 parts of silica fume; 20-35 parts of blast furnace slag; 10-15 parts of alkaline residue; 1-5 parts of an alkaline activator; the preparation method comprises the following steps: adding the steel slag, the silica fume and the blast furnace slag into a stirrer, uniformly stirring, dissolving the alkali slag into the alkali activator, adding into the stirrer after the alkali slag is completely dissolved, stirring and mixing at a low speed, pouring the standard sand into a stirring pot, stopping stirring, and stirring again to obtain alkali-activated cementing material slurry; and injecting the obtained alkali-activated cementing material slurry into a mold, carrying out condensation and hardening, removing the mold, and carrying out curing in a curing device so as to obtain the target product. The material has the advantages of good gelling property, ideal impermeability, high compressive strength and micro-expansion compensation function.
本发明属碱激发无机非金属胶凝材料领域，尤其涉及一种掺钢渣与高炉矿渣的碱激发胶凝材料，以质量份计，包括如下原料：钢渣30～50份；硅灰15～20份；高炉矿渣20～35份；碱渣10～15份；碱性激发剂1～5份；制备方法：将钢渣、硅灰、高炉矿渣加入搅拌机中搅拌均匀，再将碱渣溶于碱性激发剂中，待完全溶解后加入搅拌机，低速搅拌混合，再将标准砂倒入搅拌锅中，停拌，再搅拌，即得碱激发胶凝材料浆体；将所得碱激发胶凝材料浆体注入模具中，凝结硬化拆模，然后置于养护装置中进行养护，即得目的产品；本发明的有点效果为胶凝性好，抗渗性能理想，抗压强度高，具有微膨胀补偿功能。
