This article assesses the behavior of concrete coated with a silicone-based material. Studies were conducted to evaluate the rate of carbonation, resistance to chloride penetration, and water permeability of concrete when treated with silicone coatings. The results indicate that the water absorption, chloride ion, and carbonation resistance of concrete with a silane coating were greatly improved when compared to concrete coated with the acrylic coating used in this study and uncoated concrete. The results also show that the silane coating adher...
