Concrete and production process thereof
The invention discloses concrete and a production process thereof, relates to the technical field of concrete, and aims to solve the problems that although the currently disclosed environment-friendly concrete in the prior art has good waterproof performance, the compressive resistance of the concrete is reduced, the strength is not enough during use, the concrete is easy to deform due to compression, and the use is not reliable enough. Comprising the following components in kg/m < 3 >: 350-450 kg/m < 3 > of cement; a high-performance admixture: 70-90 kg/m < 3 >; high-quality sand: 550-600 kg/m < 3 >; 1200-1350 kg/m < 3 > of high-strength gravel; a proper amount of water; a proper amount of an additive; the high-performance admixture comprises but is not limited to fly ash, silica fume, waste steel slag, slag powder and recycled aggregate, the admixture comprises but is not limited to a water reducing agent, an air entraining agent, a pumping agent, a retarder, an accelerator, an early strength agent, a waterproof agent, a corrosion inhibitor, an anti-freezing agent, an expanding agent and a coloring agent, and the water and the admixture are properly adjusted according to the fluidity of the concrete.
本发明公开了一种混凝土及其生产工艺，涉及混凝土技术领域，为解决现有技术中目前已公开的环保混凝土虽然具有良好的防水性能，但是造成混凝土的抗压力降低，使用时强度不够，很容易受压变形，使用不够可靠的问题。包括以下按千克/立方米表示的组分：水泥：350‑450千克/立方米；高性能掺合料：70‑90千克/立方米；优质砂：550‑600千克/立方米；高强度碎石：1200‑1350千克/立方米；水：适量；外加剂：适量；所述高性能掺合料包括但不限于粉煤灰、硅灰、废钢渣、矿渣粉和再生骨料，所述外加剂包括但不限于减水剂、引气剂、泵送剂、缓凝剂、速凝剂、早强剂、防水剂、阻锈剂、防冻剂、膨胀剂和着色剂，所述水和外加剂根据混凝土的流动性进行适当调整。
