STUDIES ON ELEVATED TEMPERATURE OF FIBER REINFORCED PHOSPHOGYPSUM CONCRETE

Deterioration of concrete structures due to steel corrosion is a matter of considerable concern since the repairing of these structures proved to be a costly process. Repair and rehabilitation of the civil structures needs an enduring repair material. The ideal durable material should have low shrinkage, good thermal expansion, and substantial modulus of elasticity, high tensile strength, improved fatigue and impact resistance. Fire represents one of the most severe exposure conditions and hence provisions for appropriate fire resistance for structural members are major safety requirements for any building design.
