The utility model discloses a U-shaped mold for a concrete autogenous shrinkage test, and belongs to the technical field of concrete volume deformation tests. The U-shaped mold for testing the autogenous shrinkage of the concrete comprises a fixed support, a concrete filling part, a support, a sliding device, a measuring head and a target, the inner wall of the fixed support is in a concave semicircular ring form, the concrete filling part is hollow and is attached to the inner wall of the fixed support, the support is arranged on the upper edge of the fixed support, and the sliding device is arranged on the support. The target is in sliding connection with the support through a sliding device, the lower end of the target is located in the concrete filling part all the time, and the measuring head is fixedly connected with the upper end of the target. According to the utility model, by optimizing the mold structure, the test can be immediately carried out after the concrete is poured, the error of the test re
