Abstract
This study is a study on the flexural adhesion performance of polymer cement composites(PCCs) repair section according to the crack depth, and the flexural adhesion strength was obtained through a flexural strength test of cement mortar that was filled into cracks and repaired to a certain thickness using PCCs made of ultra high-early strength cement and polymer dispersion of EVA. As a result of the study, the flexural adhesion performance according to the crack width and crack depth was expected to decrease the flexural adhesion strength as the crack depth increased at the crack width 3.0mm, but the crack width 2.0mm and 1.5mm did not show any tendency according to the crack depth. In addition, even in the final destruction, the fact that the cracks and bottoms filled with PCCs were not cut or dropped proves that PCCs have excellent adhesion and rich toughness.
