Abstract

Polymer emulsion was used as the admixture for the purpose of increasing the mechanical properties of cement mortar. The effect of polymer emulsion admixture on compressive strength and tensile strength and chemical resistance, relative humidity on compressive and tensile strength, sand particles on water absorption were studied. The results were as follows. 1. Polymer emulson modified mortar cured under 95% of realative humidity showed lower strength than the mortar cured at dry condition. 2. The maximum strength was attained at 10~20% of polystyrene and polyacrylic acid ester polymer-cement mortar. 3. The modified mortar (sand size rate (-9＋35)mech:(-35＋60)mech=4 : 1) was 1.5 times lower than the modified mortar (1 : 1) in water absorption. 4. Compared with the ordinary mortar, the modified mortar showed 2~3 times greater chemical resistance for 5% HCl or 5% H2SO4.
