分析了硅粉混凝土的微观结构和孔结构,硅粉对于水泥浆体-骨料界面区的微结构的影响及 硅粉混凝土的渗透性。硅粉能降低混凝土的渗透性,提高混凝土的抗冻性。
The microstructure and pore structure of silica fume concrete were analyzed. The effect of silica fume on the microstructure of cement paste - aggregate interface and the permeability of silica fume concrete were analyzed. Silica fume can reduce the permeability of concrete and improve the frost resistance of concrete.
