According to the green high-performance cement concrete and the preparation method thereof, fumed silica is modified, a benzene ring structure and molecular chains with different length gradients are introduced into the surface of the fumed silica, and the purpose of improving dispersity is achieved. The modified fumed silica is used as a raw material of the concrete, and the internal pore structure of the concrete is improved, so that the salt resistance and frost resistance of the concrete are improved; the introduction of the modified fumed silica is beneficial to the combination of the matrix and the basalt fiber, and macroscopically improves the mechanical properties of the concrete.
本发明公开了一种绿色高性能水泥混凝土及其制备方法，通过对气相法二氧化硅进行改性，将苯环结构及不同长度梯度的分子链引入气相法二氧化硅的表面，达到了提高分散性的目的。本发明以改性气相法二氧化硅作为混凝土的原料，改善了混凝土内部孔隙结构，从而提升了混凝土的耐盐抗冻性能；改性气相法二氧化硅的引入有利于基体和玄武岩纤维的结合，宏观上提升了混凝土的力学性能。
