| 摘 要： | 以低硅尾矿为主要原料,经过加压成型、蒸压养护制成承重标准砖.对影响产品性能的几个重要因素,包括胶凝材料用量、成型压力、物料含水率和养护制度等进行了研究探讨.加入适量粉煤灰-矿渣基激发胶凝材料,提高水化反应速度并生成更多的托贝莫来石和CSH(I)等水化产物,进而提高砖的力学强度. |

| Abstract: | Low-silicon tailing is used as the main raw material to make the standard load-bearing brick by pressing forming and autoclaving process.The important factors influencing the product performance are investigated,including the dosage of cementing agent,forming pressure,material moisture and curing regime.The addition of alkali-activated slag/fly ash cementing material can increase the hydration reaction to produce more tobermorite and CSH(I) so as to improve the mechanical strength of the brick. |
| Keywords: | Tailings Slag Fly ash Cementing agent Autoclaved brick |
