Abstract：The effects of super absorbent polymer(SAP) on the fluidity,setting time,flexural strength and compressive strength of cement mortar under different curing temperatures were studied.The results show that the SAP has great influences on the properties of cement mortar under curing temperatures of 0,10,20 and 40 C,with its influence varying with the curing temperature.SAP can greatly improve the fluidity,decrease the fluidity loss and prolong the setting time of cement mortar under different curing temperatures,with slight influences of its addition variations on these properties.Besides,with the curing temperature decreasing,the improvement of SAP on the fluidity gradually increases.SAP can improve the flexural strength and the early aged compressive strength of cement mortar under curing temperatures of 20 and 40 C,but is not beneficial to the development of compressive strength at late age under these two curing temperatures.Additionally,SAP can slightly decrease the flexural strength and compressive strength of cement mortar under the curing temperature of 10 ℃.
