Abstract
In order to determine the best protective coating material for hydraulic concrete,the relative dynamic elastic modulus and compres-sive strength of hydraulic concrete coated with silane,anti-carbonization coating and epoxy cement were tested and analyzed with the number of freeze-thaw cycles.The results show that the relative dynamic elastic modulus and compressive strength of hydraulic concrete decrease with more freeze-thaw cycles.After coating the protective coating,the frost resistance of hydraulic concrete is significantly improved.Among them,under the condition of 200 freeze-thaw cycles,the anti-freezing performance of silane coating increased by 51.22%,and the anti-carboniza-tion coating increased by 26.31%.Therefore,it is recommended to use siloxan-based silane coatings in high cold areas and anti-carbonization coatings in middle or low cold areas as protective materials for frost resistance of hydraulic concrete.关键词
