Preparation method of mortar interface transition zone sample

The invention provides a preparation method of a mortar interface transition zone sample, and relates to the technical field of sample preparation. A to-be-bonded surface of a base material is cut to form a plurality of first cutting seams, and the first cutting seams are filled with filler. And the forming frame is installed on the upper portion of the base material, so that the forming frame and the to-be-bonded face are matched to define a forming cavity, and mortar is added into the forming cavity. And the mortar block in the forming cavity is cut to form second cutting seams which are overlapped with the first cutting seams in a one-to-one correspondence manner. Due to the existence of the first cutting seam and the second cutting seam, after the mortar block is solidified, a plurality of mortar interface transition area samples can be obtained only by separating the mortar block from the base material along the first cutting seam. As a cutting machine is not needed to cut the mortar block and the base m
