Method for improving corrosion resistance of Portland cement
The invention discloses a method for improving corrosion resistance of Portland cement. The effect is realized by three aspects of formula control, grain composition control and control in a preparation process. According to the method, unbonded silica sand, fly ash, a preservative and the like are added into Portland cement, and different grain grading is controlled, so that the compactness of a hardened cement paste can be effectively improved, and compared with conventional Portland cement in the prior art, the corrosion resistance of the Portland cement is improved.
本发明公开了一种改善硅酸盐水泥抗腐蚀性能的方法，通过配方控制、颗粒级配控制、制备过程中的控制这三个方面来实现。本发明通过在硅酸盐水泥中加入矽砂、粉煤灰、防腐剂等，且对不同颗粒级配控制，能够有效提高水泥浆体硬化后的密实度，相比现有技术中常规硅酸盐水泥而言，其抗腐蚀能力得到了提升。
