Research on Mechanical Properties of Polymer Modified Mortar

摘要：

In this article, the mechanical properties of cement mortar with different polymer-cement were studied. The mechanical properties included flexural and compressive strength, elastic modulus and bonding strength. The results demonstrates that: the compressive strength of mortar with 15％ polymer-cement ratio is 12.3％ higher than that of underlying ordinary mortar; the improvement of flexural strength of mortar is even larger, the mortar with 15％ polymer-cement ratio is 92.1％ higher than the ordinary mortar; with the increase of polymer-cement ratio, the flexural strength gradually increases. The elastic modulus of polymer-modified mortar is lower than that of underlying ordinary mortar, the elastic modulus gradually decreases as the polymer-cement ratio increases and the mortar with 15％ polymer-cement ratio is 40.2％ lower than the ordinary mortar. The bonding strength increases as the mixing amount of polymer increases, the mortar with 15％ polymer-cement ratio is 12.1％ higher than the ordinary mortar, but the increase is limited after the polymer-cement ratio exceeds 10％.
