High-strength concrete prepared from industrial tailings and preparation method of the high-strength concrete
The invention discloses high-strength concrete prepared from industrial tailings. The high-strength concrete comprises the following raw materials: 420 to 440 kg/m<3> of a binder material; 70-90% of cement; 30-40% of an admixture; 20 to 30% of silica sand; 20-40% of slag; 20 to 40% of tailings; 0.7-1% of a water reducing agent; wherein the water-binder ratio of each cubic meter is 121.5 to 130.2 L. In particular, the concrete comprises the following raw materials: 430 kg/m<3> of the binder material; 80% of the cement; 35% of the admixture; 25% of the silica sand; 30% of the slag; 30% of the tailings; and 0.9% of the water reducing agent, the water-binder ratio of each cubic meter being 125.8 L. The silica sand comprises tailings of a silica powder raw material for producing glass, the fineness modulus of the silica sand is 2.6-3.5; the slag is mainly composed of an inert material, and other reactions cannot be generated after the slag passes through a high-temperature and high-pressureenvironment. The industrial tailings are used for replacing aggregate to be applied to concrete, the environmental protection pressure of other industries can be greatly relieved, and meanwhile the problem that gravel resources in the concrete industry are deficient can be solved. Technical support is provided for enterprises to realize ecological development, green development and sustainable development.
本发明公开了一种利用工业尾料制作的高强混凝土，包括的原料如下：胶材420‑440kg/m，水泥70‑90％，掺合料30‑40％，硅砂20‑30％，炉渣20‑40％，尾矿石20‑40％，减水剂0.7‑1％，每立方米水胶比121.5‑130.2L，包括的原料如下：胶材430kg/m、水泥80％、掺合料35％、硅砂25％、炉渣30％、尾矿石30％、减水剂0.9％，每立方米水胶比125.8L/m，所述硅砂包括生产玻璃用硅粉原料的尾料，所述硅砂细度模数为2.6～3.5之间，所述炉渣主要由惰性材料组成，经过高温高压环境以后不会产生其他的反应。本发明利用工业尾料代替骨料在混凝土中应用，不仅可以大大缓解其他产业的环保压力，同时还可以解决混凝土行业砂石资源匮乏的问题。为企业实现生态发展、绿色发展和可持续发展提供了技术支撑。
