Experimental Research on Splitting Tensile Behavior of  Adhesion of Polymer Mortar and Concrete/Cao Jun,Wang Zhihao(Department of Civil Engineering,Tsinghua University,Beijing 100084,China)
Abstract:The research on adhesion of polymer mortar and concrete has important theoretical and practical meanings for the repairing and strengthening concrete structures.The test results show that the splitting section arises in the adhesive section of polymer mortar and concrete,and the adhesive splitting tensile strength increases with the increasing of concrete strength.
Keywords:polymer mortar;adhesive splitting tensile strength;concrete strength
