Resistance to Nitric Acid Corrosion of Latex Modified Sulphoaluminate Cement Mortar

Abstract:

The correlation performance between polymer/cement ratio and corrosion resistance to nitric acid of latex modified sulphoaluminate (SA) cement mortar was investigated by testing the compressive strength, flexural strength and weight change rate of latex modified SA cement mortar in the nitric acid solution at different ages. In addition, considering the appearance of the specimen, the results show that the corrosion resistance to nitric acid of latex modified SA cement mortar is influenced positively by the polymer/cement ratio. With the ratio of emulsion to cement increasing, the corrosion resistance to nitric acid was enhancement. when the polymer/cement ratio was 0.2, the latex modified SA cement mortar showed the best performance in compressive strength, flexural strength, weight change rate and the appearance.
