Research on Frost Resistance of Cement Motar Corroded by Sulphate

SANG Yu;Hangzhou Highway Administration;  
Cement motar specimen was used to study the corrosion of sulphate,with its changes in flexural strength,compressive strength and mass revealing the factors that affect the corrosion resistance of cement motar.Scanning electron microscope was applied to observe the microstructure of the specimen which has being corroded.The results show that when the concentration of the sulphate solution is fixed,lowering the water-cement ratio will significantly improve the corrosion resistance;adding coal ash can also enhance cement motar's resistance to corrosion.
