摘要：为了提高水泥基材料的抗碳酸腐蚀性能，通过碳酸腐蚀前后砂浆的外观、质量、抗压强度和腐蚀深度的变化，研究了粉煤灰和硅灰的掺量、掺入方式（单掺、复掺）对砂浆抗碳酸腐蚀性能的影响。结果表明：单掺时，粉煤灰和硅灰的最佳掺量分别为15%、5%；复掺时，当m粉煤灰∶m硅灰=7∶3时，砂浆的抗碳酸腐蚀性能最佳，且优于单掺粉煤灰或硅灰砂浆的性能。 Abstract: In order to improve the carbonic acid corrosion resistance of cement-based materials, the effects of the contents and addition methods(single addition or compound addition) of fly ash and silica fume on the carbonic acid corrosion resistance of mortar were studied by examining the changes in appearance, mass, compressive strength, and corrosion depth of mortar before and after carbonic acid corrosion. The results show that the optimal content of fly ash and silica fume is 15% and 5% respectively when added alone. When mixed, the mortar has the best carbonic acid corrosion resistance when mfly ash∶msilica fume is 7∶3， and which is superior to the performance of the mortar when only fly ash or silica fume is added.

The results show that the optimal content of fly ash and silica fume is 15% and 5% respectively when added alone. When mixed, the mortar has the best carbonic acid corrosion resistance when m_{fly ash}∶m_{silica fume} is 7∶3， and which is superior to the performance of the mortar when only fly ash or silica fume is added.
