摘要：
The correlation between the ratio of styrene-acrylic latex to sulphoaluminate cement and the resistance of latex modified sulphoaluminate cement mortar to hydrochloric acid corrosion was investigated. The weight change rate, compressive strength, and flexural strength of various latex modified cement mortar in the hydrochloric acid solution at different ages were tested and the samples appearance was observed. The results show that the resistance of latex modified sulphoaluminate cement mortar to hydrochloric acid corrosion is related to the latex/cement ratio. With the increase of the latex/cement ratio, the resistance performance of sulphoaluminate cement mortar to hydrochloric acid corrosion was improved firstly and then decreased. When the polymer/cement ratio was 0.2, the latex modified cement mortar presented the highest ability in compressive strength, flexural strength, weight change rate, and the appearance, showing its excellent resistance to hydrochloric acid corrosion.
