To identify effect of fibers on durability properties of concrete due to chloride penetration

Concrete durability is a paramount concern due to its, direct impact on the infrastructure longevity and structural integrity. Rapid chloride penetration and electrical resistivity are pivotal parameters for assessing durability, where chloride ingress leads to reinforcement corrosion and resistivity reflects pore connectivity and moisture content. This study investigates the efficacy of diverse fiber blends and curing compounds in bolstering concrete durability, employing the Electric Resistivity Test and Rapid Chloride Penetration Test (RCPT) for evaluation. Through a comprehensive literature review and experimental exploration, various fiber types, proportions, and curing compounds were scrutinized. Concrete specimens reinforced with 0.66% Steel fibers, SF 0.36% + 0.3% GF, SF 0.36% + 0.3% PPF were cured with different compounds and tested for chloride penetration and electrical resistivity. Results unveiled the substantial decrease of chloride penetration and electric resistivity in fiber-reinforced concrete compared to plain concrete is approximately 25% and 65% respectively. Amongst all the curing compounds used Fosroc concure 1315 and Razon CCC 105 ACY exhibits best results.
