Waterproof concrete and preparation method thereof
The invention discloses waterproof concrete and a preparation method thereof, and particularly relates to the technical field of concrete preparation, a mixture of fly ash and superfine slag powder is adopted as a mineral admixture, glass beads in the fly ash can reduce the viscosity of cement mortar and the friction force between particles, cement particles are fully dispersed, and the waterproof performance of the concrete is improved. The adopted superfine slag powder improves the pozzolanic effect and increases chemical interaction and induced excitation among particles, the chemical activity of the fly ash is relatively low, the influence on the early strength of the concrete is relatively large, the chemical activity of the superfine slag powder is relatively high, and the superfine slag powder and the fly ash complement each other, so that the anti-seepage performance of the concrete is improved. The concrete has the advantages that a single mixed material does not have excellent effects, the strength of the concrete is more ideal, the condition that more pores are not easy to appear in the concrete is ensured, and the waterproof performance and the frost resistance of the concrete are better.
本发明公开了一种防水混凝土及其制备方法，具体涉及混凝土制备技术领域，本发明通过采用粉煤灰与超细矿渣粉的混合物作为矿物掺和料，粉煤灰中玻璃微珠能使水泥砂浆的粘度和颗粒之间的摩擦力降低，使水泥颗粒充分分散，形成对水泥内部的填充，使得混凝土内部结构密实，抗渗性能更佳，且采用的超细矿渣粉，提高火山灰效应，增加各微粒间的化学交互和诱导激发，粉煤灰的化学活性相对较低对混凝土早期强度影响较大，超细矿渣粉的化学活性较高，二者互补，产生单一混合材所不具有的优良效果，保证混凝土自身的强度更为理想，且保证混凝土内部不易出现较多孔隙的情况，使其防水性能和抗冻性能更佳。
