Building Materials Corrosion Control

This paper highlights the beauty of fiber reinforced polymers (FRP) in the field of corrosion protection reinforced concrete structures (RCS). The fiber reinforced polymers develop anticorrosive barrier on the surface reinforced concrete and minimize the attack of corrosive pollutants. Corrosion is major problems with reinforced concrete. It occurs due to interaction of acids, alkalis, salts, pollutants, particulates, heat, light microorganisms and macro organisms and its own morphology. These substances create hostile environment for building materials of concrete and they produce chemical and corrosion reactions. The other factors also influence the corrosion of materials like acid rain, wind and weathering effects. The industrial effluents, flues gases and wastes provide major role in the field of concrete corrosion. These reactions change their mechanical, physical and chemical properties and tarnish their facial appearance. When building materials of concrete come in contact of corrosive environment, they can develop corrosion cell in presence of electrolyte. The corrosion reactions aggravate with rebar steel of concrete and their deterioration starts. There are several forms of corrosion occurs with iron bar of concrete such as galvanic, pitting, crevice, stress, intergranular, blistering, embrittlement, erosion, cavitations, observes inside and outside of materials. Building materials of concrete also show chemical reaction with corrosive substances and produce dissolving and swelling(
