聚合砂浆与混凝土粘结劈拉强度的试验研究

Experimental Research on Splitting Tensile Behavior of Adhesion of Polymer Mortar and Concrete

进行了砂浆和不同强度混凝土的粘结劈拉试验,试验结果表明,聚合砂浆与混凝土之间的劈拉破坏为粘结面破坏,粘结劈拉强度随混凝土强度的增大而增大。

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.
