Study on Corrosion Resistance of N-vinyl Pyrrole Modified Cement

摘要

Ordinary Portland cement in corrosive environment such as saline-alkali land, sea water and chemical pollution can easily be corroded, thus cause infrastructure damage. In this paper, N-vinyl pyrrole was added into cement mortar, to improve sulphate erosive resistance of cement material. Through strength testing, quick sulfate corrosion test, XRD and SEM analysis methods in experiment, the researching results have shown that NVP can effectively improve the property of cement.
