Study on the Application of High Fluid Mortar for Patching Material

Abstract

The purpose of this study is to investigate the application of high fluid mortar for patching materials. Patching works are used for popular methods to repair or strengthen the concrete structures. In the case of bigger volume is required in replacing the concrete member, patching with framework or spraying is applied as recasting method. This paper describes the possibility of high fluid mortar, which can be used for patching materials under severe conditions. This high fluid mortar has been developed for non-shrinkage grouting materials. The main improvement in this investigation is to add polyester based shrinkage reducer and mix the polyolefin based plastic fibers complexly.
