Polymer mortar develops remarkable setting shrinkage compared with ordinary cement mortar. In this study, stresses and deformations of concrete member repaired by polymer mortar due to setting shrinkage of polymer mortar were investigated experimentally and analytically. Stresses and deformations of the member due to setting shrinkage of polymer mortar were measured and estimated analytically. It is possible to estimate the initial stress inducted into the concrete member and the deformation of the member due to the setting shrinkage of the polymer mortar.
