Degradation of Building Materials by Corrosive Pollutants
Abstract: Fiber reinforced polymers (FRP) is used for the corrosion suppression of reinforced concrete structures (RCS). One of the main issues with reinforced concrete constructions is corrosion. It interacts with acids, alkalis and salts to produce disintegration in building materials components. Pollutants and effluents speed up disbanding inside and outside reinforced structures. Bio-wastes come in contact of building materials to develop miro and macro-organism and these organisms release acid substances to …
