Anti-crack and anti-seepage nickel sand aggregate premixed concrete and preparation process thereof
The invention provides anti-crack and anti-seepage nickel sand aggregate premixed concrete and a preparation process thereof. The premixed concrete comprises the following raw material components: 150-200 parts of cement; 50 to 90 parts of nickel sandstone powder; 250 to 350 parts of nickel sandstone fine sand; 500 to 1000 parts of nickel sand coarse sand; 40 to 60 parts of fly ash; 11 to 20 parts of reinforcing fiber; 50-70 parts of a water-absorbing elastomer; and 170 to 200 parts of water. The principle that the volume of the nickel sandstone is increased in the later hydration process is ingeniously utilized, the volume shrunk by the water absorption elastomer is compensated, and therefore when rainwater permeates into the concrete, the water absorption elastomer can absorb water permeating into gaps in the concrete to expand so as to fill the cracked or leaked concrete; and the anti-cracking and anti-seepage concrete has high-efficiency anti-cracking and anti-seepage performance.
本发明提供了一种抗裂防渗型镍砂石骨料预拌混凝土及其制备工艺，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50‑90份；镍砂石细砂250‑350份；镍砂石粗砂500‑1000份；粉煤灰40‑60份；增强纤维11‑20份；吸水弹性体50‑70份；水170‑200份。巧妙的利用了镍砂石在后期水化过程中体积的增加的原理，弥补了吸水弹性体所收缩的体积，因此当雨水渗入混凝土内时，可以通过吸水弹性体进行吸收混凝土内间隙渗入的水分进行膨胀以填充该部分开裂或渗漏的混凝土内部，起到封闭堵塞渗漏的作用，具有高效的抗裂和防渗性能。
