An Efficient Environmentally-Friendly Materials for Concrete Building Protection

Abstract:

The concrete building protection materials is widely in the hydraulic and bridge engineering. In the external environment, water, chloride ion, deicing salt and freeze-thaw cycle is the greatest enemy of the concrete builidng , leading to concrete corrosion damage. we found that silane materials is an efficient materials for building protection ，water absorption rate of silicone protected specimens is no more than 0.004 mm/min^0.5and the chloride diffusion coefficient was clearly reduced. The silane can penetrate into a few centimeters below the surface of the concrete structure to provide long-term protection. So the silane materials is considered the most suitable for concrete protection.
