Influence of Air Pressure Difference and Epoxy Resin Layer on Concrete Gas Permeability
Based on the Cembureau method,the gas permeability coefficient of concrete under different air pressure differences was measured,and the influence of air pressure difference and epoxy resin layer on the gas permeability of concrete was studied.The results show that the gas permeability coefficient of concrete decreases with the increase of air pressure difference within a certain range.Epoxy resin layer can effectively reduce the gas permeability coefficient of concrete.
