Abstract: Abstract:In this study, the influences of the cement-based surface coating on concrete's physical properties and durability are evaluated. Two environments including the outdoor exposure and exposure to a ultra-violet light environment are used to evaluate the durability of this surface coating material. The experiments include the permeability, water absorption rate, four-probe Wenner's resistivity, open circuit potential, accelerated chloride diffusion, rapid chloride penetration test and accelerated carbonation. The results indicate that the surface coating material make concrete having lower permeability coefficient, water absorption rate, corrosion risk, chloride diffusion coefficient, RCPT value, carbonation rate and higher resistivity. In addition, such an effect becomes more apparent as thicker coating thickness is used. Furthermore, after fourmonth exposure to the outdoor environment and ultra-violet light no apparent degradation of the coating material is found. Overall speaking, the surface coating material can build a cover on the concrete's surface to hinder the penetration of hazard elements into the concrete such that the concrete's durability is improved.
