Abstract
In order to improve the durability of cement mortar,the effects of graphene oxide content on the chloride erosion resistance of cement mortar were investigated through dry and wet cycle tests.The results show that the concentration and decreasing range of chloride ions decrease first and then increase with the increase of GO content,and the peak value is at the position where the GO content is 0.06%.The free chloride ion concentration of GO cement mortar is lower than that of ordinary cement mortar.With the increase of oxidation age,the chloride ion erosion resistance and change range of graphene oxide cement mortar are reduced.With the increase of depth,the free chloride ion concentration of GO cement mortar first decreased rapidly,then increased slightly and then stabilized(more than17.5 mm).The free chloride concentration of ce-ment mortar increases with increasing age,but the rate decreases with decreasing depth.In summary,the optimal content of graphene oxide was determined to be 0.6%.关键词
