Evaluation of the Effectiveness of Silicon Protective Agent for High-grade Concrete
Silane impregnating materials such as n-octyltriethoxysilane,isooctyltriethoxysilane(liquid,paste)and isobutyl triethoxysilane are used to impregnate high-grade concrete specimens,and indicators such as water absorption ratio,alkali resistance,penetration depth and volatility are tested.The results show that isooctyltriethoxysilane paste had the best protective effect,while n-octyltriethoxysilane had the lowest content of active ingredients,and isooctyltriethoxysilane paste is superior to isooctyltriethoxysilane liquid.
