Research on Nitric Acid Corrosion Resistance of Latex Modified Ordinary Portland Cement Mortar

Abstract:

The relationship between the ratio of styrene-acrylic latex to ordinary Portland cement (OPC) and the nitric acid corrosion resistance of latex modified ordinary Portland cement mortar was studied. The compressive strength and flexural strength of latex modified cement mortar in the nitric acid solution at different ages were tesed and the samples appearance was observed. The results show that the nitric acid corrosion resistance of latex modified OPC mortar is influenced positively by the latex/cement ratio. With the ratio of emulsion to cement increasing, the nitric acid corrosion resistance ability of OPC mortar was enhanced firstly and then decreased. When the polymer/cement ratio was 0.2, the latex modified cement mortar showed the best performance in compressive strength, flexural strength, and the appearance.
