Abstract：With the modified silicone resin lotion as the main film-forming material,modified silicone concrete surface rein-forcement agent is prepered by adding inorgaaic materials such as lithium silicate,talcum powder and magnesium fulorosilicate,as well as auxiliaries such as penetrant.The influence of the content of basic lotion,lithium silicate,talcum powder,magnesium fluo-rosilicate and penetrant on the performance of surface reinforcement was studied.It was found that when the modified silicone resin lotion was diluted to 20％solid content,and then 3％talcum powder,4％lithium silicate,5％magnesium fluorosilicate and 1％penetrant were separately added,the penetration depth of the modified polymer concrete surface reinforcement in C30 concrete could reach 12 mm.The viscosity,pH value,and film-forming time meet the requirements of JC/T 949-2021"Release Agents for Concrete Products",and the freeze-thaw stability meets the requirements of GB/T 43273-2023"Determination of Freeze Thaw Sta-bility of Pesticides".The surface strength improvement rate was 19.4％,and the rebound strength improvement effect was good.
