The paper mainly studies the effects of polymer on the mechanical strength and microstructure of mortar, and analyses the influence of 1%, 5%, and 10% polymer content, and curing methods on the strength growth and microstructure. The results show that the addition of polymer prolongs the initial and final setting time. When the polymer content is less than 10%, the compressive strength gradually decreases with the increasing polymer content, and the flexural strength of mortar after polymer addition decreases slightly. The mechanical strengths are the best under 7 days of water curing and 21 days of air curing. SEM analysis shows that high content of polymer will delay and inhibit the hydration of cement, and introduce a certain amount of bubbles, thus affecting the strength.
