Abstract

Polymer mortar is generally used for repairing concrete structures. However, its behavior in the setting characteristics has not fully been explored.<br>In this study, shrinkage strain and stress in the setting process of polymer mortoar with three kinds of resin were measured with an original test apparatus incorporating a non-contact type displacement meter and load cells.<br>Then, stress and deformation of two-layer composite beams composed of polymer mortar and ALC were investigated. Furthermore, from the viewpoint of energy at setting of polymer mortar, characteristics of polymer mortars used were discussed.
