Abstract：The influence of latex powder,tartaric acid,cementitious materials,aggregate grading and curing agent on abrasion resistance of calcium aluminate cement-based self-leveling mortars (SLM) have been studied,and relativities between abrasion resistance and flow value,strength were analyzed as well. Results show that latex powder may enhance the wear resistance of SLM by improving its stability and flexibility. Tartaric acid may increase the mortars segregation settling extent,which will lead to decreasing of abrasion resistance. For calcium aluminate cement-based ternary system self-leveling mortars,increasing content of ordinary Portland cement and calcium sulfate moderately are propitious to wear resistance. Besides,the decreasing content of cementitious materials cause degradation of abrasion performance. Mortars with 20% 40~70 mesh sand and 20% 70~140 mesh sand present the superior abrasion resistance. By brushing curing agent,mortars surface exhibit a significant increasing in density and abrasion resistance. When curing agent reaches the saturation dosage,the improvement of abrasion resistance is not obvious.
