Dependence of building component temperature on the mechanical properties of polymeric materials for crack repair

This basic research is that focused on that not only repair effect immediately after the repair (initial performance) but also necessity of valuate its persistence in the environment of various weather in order to select a reasonable crack repair materials. In this report, we simulated the temperature of weather in japan at the laboratory level to perform bending tests, environment under -10°C, 5°C, 23°C, 40°C and 60C, for mortar specimens that were subjected to single repair material and repair cracks, so we extracted four types of materials, three types of epoxy resins repair materials and one type of acrylic resin repair material, that are widely used as a crack repair materials. The results shows importance that to clarify the effect that the decline of repair materials or change of a single repair materials are quite different for each repair materials and to evaluate the persistence of the effect repair.
