A Study on the Effects of Polymer in Repairing Mortar

In general, the polymer is mainly used with the cement mortar with various admixtures for concrete repair. The properties of cement-polymer mortar was studied by the cement-polymer ratio only and ignored any influence of admixtures in the mortar. Therefore in this study, the test is carried out with 2 product of polymers(the same type produced by different companies) and various admixtures. It is found that the same type of polymers produced by different companies affect the properties of fresh and hardened concrete. As increasing the polymer proportion in mortar, the compressive strength and flexural strength are increased, and also drying shrinkages is increased.
