Portland cement and preparation method thereof
The invention discloses Portland cement and a preparation method thereof, the Portland cement is prepared from the following materials: 50-85% of cement, 8-40% of granulated blast furnace slag powder, 3-7% of fly ash, 3-7% of silica fume and 5-8% of steel slag powder, the ratio of the cement is 50-85%, the ratio of the granulated blast furnace slag powder is 8-40%, the ratio of the fly ash is 3-7%, the ratio of the silica fume is 3-7%, and the ratio of the steel slag powder is 5-8%. The mineral powder, the coal ash, the silica fume, the steel slag powder and other mixed materials are doped into the pure Portland cement, so that the comprehensive performance of the concrete is improved to a certain extent, and the concrete adopting the pure Portland cement, the mineral powder, the coal ash, the silica fume and the steel slag powder five-component composite cementing material is improved to a certain extent. The comprehensive performance of the concrete is superior to that of concrete prepared from a ternary composite cementing material of pure Portland cement, mineral powder and fly ash, and is better than that of concrete prepared from a binary composite cementing material singly doped with one mixed material or pure Portland cement, and the chloride ion corrosion resistance of the concrete is improved to different degrees by different mineral mixed materials. And the composite doping of the mineral mixed material has a better effect than the single doping of the mineral mixed material.
本发明公开了一种硅酸盐水泥及其制备方法，包括如下材料组合而成，水泥、粒化高炉矿渣粉、粉煤灰、硅灰、钢渣粉，其中，水泥的配比在50‑85%、粒化高炉矿渣粉的配比在8‑40%、粉煤灰的配比在3‑7%、硅灰的配比在3‑7%、钢渣粉5‑8%，通过在纯硅酸盐水泥中掺入矿粉、粉煤灰、硅灰、钢渣粉等混合材对混凝土综合性能都有一定程度的改善，而采用纯硅酸盐水泥、矿粉、粉煤灰、硅灰、钢渣粉五元复合胶凝材料的混凝土，其综合性能要优于纯硅酸盐水泥、矿粉、粉煤灰的三元复合胶凝材料的混凝土，更优于单掺一种混合材料的二元复合胶凝材料或纯硅酸盐水泥的混凝土，而且不同矿物混合材料对混凝土抗氯离子侵蚀性能均有不同程度的改善，并且矿物混合材料的复合掺入比单独掺入具有更加良好的效果。
