Connecting bases 4 are fixed at the four corners of the top of the transparent plate 1. Fixing buckles 5 are provided on the outside of the two sets of connecting bases 4 on one side of the transparent plate 1, and fixing inserts 6 are provided on the outside of the two sets of connecting bases 4 on the other side of the transparent plate 1. Multiple sets of transparent plates 1 are connected and combined with each other through the fixing buckles 5 and fixing inserts 6 on both sides to form the main structure of the concrete elastic modulus measurement marking and positioning plate. In use, the transparent plate 1 is placed on the surface of the concrete standard test block to be tested, and the concrete standard test block is positioned and marked through the positioning holes 2 and auxiliary positioning lines 3. The marking and positioning plate composed of the transparent plate 1, positioning holes 2 and auxiliary positioning lines 3 is portable and convenient, simple to manufacture and easy to process, highly practical and widely applicable.
