Environment-friendly premixed concrete prepared from construction waste
The invention provides environment-friendly premixed concrete prepared from construction waste. The environment-friendly premixed concrete is prepared from the following raw material components: 150-200 parts of cement; 150 to 190 parts of nickel sand stone powder; 350 to 450 parts of recycled fine aggregate; 200 to 300 parts of recycled coarse aggregate; 50 to 60 parts of fly ash; 11 to 20 parts of reinforcing fiber; 1-3 parts of a water reducing agent; and 170 to 200 parts of water. The nickel sand and stone powder prepared from the nickel slag is used as a raw material, so that the microstructure of the concrete becomes compact, the microcosmic pore structure of the concrete is further improved, the porosity is reduced, and the anti-permeability and freeze-thaw resistance of the concrete are improved; and a disordered supporting system is formed in the concrete through the reinforced fibers, so that the anti-permeability and freeze-thaw resistance of the recycled concrete are effectively improved.
本发明提供了一种利用建筑垃圾制备的环保型预拌混凝土，所述预拌混凝土的原料包括如下组分：水泥150‑200份；镍砂石粉末150‑190份；再生细骨料350‑450份；再生粗骨料200‑300份；粉煤灰50‑60份；增强纤维11‑20份；减水剂1‑3份；水170‑200份。利用镍渣制得的镍砂石粉末作为原料，使得混凝土的微观结构变得较为致密，进一步改善混凝土的微观孔结构，降低孔隙率，提高了混凝土的抗渗性能和抗冻融性能；通过增强纤维在混凝土内部形成一种乱向支撑体系，有效提高再生混凝土的抗渗和抗冻融性能。
