本文通过测试不同配合比混凝土的刻蚀深度，研究抗压强度、砂率、水灰比、坍落度、单方水泥用量、单方砂用量、单方石子用量、单方水用量对刻蚀深度的影响规律。最终得出结论：抗压强度越大，刻蚀深度越小。

By testing the etching depth of concrete with different mix proportion, this paper studies the influence of compressive strength, sand rate, water cement ratio, slump, amount of cement per cubic meter, amount of sand per cubic meter, amount of stone per cubic meter and amount of water per cubic meter on the etching depth. Finally, it is concluded that the greater the compressive strength, the smaller the etching depth.
