The influences of 020℃ curing systems on the tensile bonding strength of HEMC EVA modified cement mortar cured for 28d were studied. The results show that with different type and content of polymers, the curing system has very different effect on the tensile bonding strength of polymer modified cement mortar. 5℃ constant temperature and 20℃/5℃ cycle curing systems are most suitable for the development of the tensile bonding strength of HEMC modified cement mortar. With the increase of curing temperature, the tensile bonding strength of EVA modified cement mortar increases. However, cycle curing systems do not significantly improve the tensile bonding strength of EVA modified cement mortar.
