对普通硅酸盐水泥混凝土以及改性混凝土进行pH=1的盐酸腐蚀,在腐蚀60d后,各种混凝土的立方体抗压强度均有不同程度的降低。适量的粉煤灰和硅灰可以一定程度地提高混凝土的抗酸性腐蚀性能,而丁苯胶乳的加入却会降低混凝土的这种抗酸性腐蚀性能。

In this paper,ordinary Portland cement concrete and modified concrete were corroded by hydrochloric acid which pH=1.After 60 days of corrosion,the cube compressive strength of every sample is reduced in different degree,from which we can know that amount of fly ash and fume can increase the resistance ability to acid corrosion to some degree but the styrene-butadiene latices reduced this ability of concrete.
