Study the Impact of Corrosive Pollutants on Building Materials Corrosion
Abstract: Reinforced concrete structures (RCS) may be made more resistant to corrosion by using fiber reinforced polymers (FRP). One of the primary concerns with reinforced concrete constructions is corrosion. It causes disintegration in building material components by interactions with salts, acids, and alkalis. Both within and outside of reinforced properties, pollutants and effluents accelerate disbanding. When bio-waste and building materials come into contact, microorganisms and macro organisms, grow and emit acid …
