摘要: 以矿渣和尾矿为主要原料,氢氧化钠为激发剂,工业液体硅酸钠作结构模板剂,制备了无机矿物聚合物材料,分别对不同制备条件的地质聚合物的7 d抗压强度进行测试。结果表明,尾矿质量为矿渣质量的80%时所得到的产品的抗压强度最大,为45.10 MPa。Na2SiO3与NaOH的质量比为50%∶50%时所得到的产品的抗压强度最大,为63.79 MPa。固液比为0.35时所得到的产品的抗压强度最大,达38.35 MPa。养护期为14 d时所得到的产品的抗压强度最大,达71.25 MPa。加入钢渣量为固体总量20%时抗压强度最大,为61.86 MPa。

Abstract: Taking tailings and blast furnace slag as main raw materials, sodium hydroxide as activator, and the sodium silicate of industrial liquid as templating agent, geo-polymers was prepared. And its compressive strength in 7 d under different preparation conditions was tested. The result indicated that geo-polymer reach maximum compressive strength in 7 d to  5.10 MPa when tailings occupy 80% of blast furnace slag. As the mass ratio of Na2SiO3 and NaOH is 50%∶50%, the compressive strength in 7 d can reach maximum compressive strength of 63.79 MPa. As the solid-to-liquid is 35%, the compressive strength in 7 d can reach maximum 38.35 MPa; As the curing period is 14 d, the compressive strength can reach maximum 71.25 MPa. As the steel slag in solid is 20%, the compressive strength can reach maximum 61.86 MPa.
