Sulfate-erosion-resistant concrete preservative and preparation method thereof
The invention relates to the technical field of civil engineering materials, and particularly discloses a concrete sulfate corrosion resistant preservative and a preparation method thereof. The sulfate corrosion resistant concrete preservative comprises the following components in percentage by mass: 37%-59% of tailing slag, 3%-10% of water glass, 10%-19% of barium salt, 20%-33% of neoprene latex and 1%-2% of latex modifier. The tailing slag comprises tailings of at least one of lithium ore, iron ore, copper ore, chromium ore and manganese ore, and the Si/Ca mass ratio of the tailing slag is 4.0-10.0. The sulfate corrosion resisting preservative has a good sulfate corrosion resisting effect, the sulfate corrosion resisting coefficient of the concrete can reach 0.90 or above by using the sulfate corrosion resisting preservative for the concrete, the sulfate corrosion resisting performance of the concrete is obviously improved, and excessive influence on the mechanical strength of the concrete is avoided.
本申请涉及土木工程材料技术领域，具体公开了一种混凝土抗硫酸盐侵蚀防腐剂及其制备方法；其中混凝土抗硫酸盐侵蚀防腐剂，按照质量百分比包括以下组分：37％～59％的尾矿渣、3％～10％的水玻璃、10％～19％的钡盐、20％～33％的氯丁胶乳、1％～2％的胶乳改性剂；所述尾矿渣包括锂矿、铁矿、铜矿、铬矿、锰矿中至少一种的尾渣，所述尾矿渣的Si/Ca质量比为4.0～10.0。该抗硫酸盐侵蚀防腐剂具有很好的抗硫酸盐侵蚀的效果，使用本发明的混凝土抗硫酸盐侵蚀防腐剂，混凝土抗硫酸盐侵蚀系数可达0.90以上，混凝土的抗硫酸盐侵蚀性能得到了明显提高，且不会对混凝土的力学强度产生过多的影响。
