Abstract

The purpose of this study is to evaluate the viscosity and flowability of polymer-cement composites for repairing cracks of RC structures. The viscosity and flowability of the polymer cement composites differed greatly depending on the type of polymer and the polymer cement ratio, and the polymer cement composites could be produced that could repair fine cracks in the RC structure without material separation by adjusting the proper water-cement ratio. In particular, the mixing of high viscosity EVA-modified polymer composites could be adjusted.
