Injecting resins into crack is a generic method for repair of concrete members. Assessing in advance the injection behavior is important to decide the repair method in actual construction.
In this paper, specimens that simulated an actual crack of concrete were produced using a 3D scanner and a 3D printer. One of a pair of the specimens was made of a transparent material, therefore it became possible to estimate the injection behavior by visual observation. In this experiment, it was possible to evaluate the initial extent of injection and the dribble of the repair materials in the same shape crack.
