本文通过设计环保型阻锈功能组分,并将矿渣、粉煤灰、硅灰等进行工艺复合,研制改性辅助胶凝材料。同时,通过抗硫酸侵蚀性能、电通量等测试,考察了改性辅助胶凝材料对高强度混凝土耐久性能的影响,结果表明:研制的改性辅助胶凝材料能有效地改善了混凝土的微观结构,并且有着较好的电化学性能,设计的C40混凝土抗硫酸盐侵蚀系数大于1.1,电通量小于500 C,在海洋工程混凝土结构中有着较好的应用前景。
In this paper, the design of environmentally friendly rust-inhibiting functional components, and the slag, fly ash, silica fume and other processes for the composite, the development of modified auxiliary cementitious materials. At the same time, the influence of modified assistant cementitious material on the durability of high strength concrete was investigated by the test of anti-sulfuric acid corrosion resistance and electric flux. The results show that the modified assistant cementitious material can effectively improve the microstructure of concrete Structure, and has good electrochemical performance. The designed sulfate resistance of C40 concrete is greater than 1.1 and the electric flux is less than 500 C, which has a good application prospect in marine engineering concrete structures.
