Abstract

Post-fire curing has proven to be an effective repair method in restoring the structural integrity of concrete structures affected by fire. Various post-fire curing methods have been explored in previous research; however, the practical feasibility of these methods remains a major concern. An experimental investigation is carried out to evaluate the effects of two distinct post-fire curing techniques on the strength recovery of fire-damaged concrete cylinders. The employed methods include a) submerged water tank curing and b) water curing using jute bags, both administered over a 28-day period. The study assesses the influence of these post-fire curing techniques on the restoration of mechanical and dynamic properties through Uniaxial Compressive Strength, Ultrasonic Pulse Velocity (UPV), and Impact Hammer Modal Testing. Experimental results reveal that both curing methods exhibit notable effects on residual compressive strength and dynamic recovery of concrete cylinders following exposure to elevated temperatures. Significantly, the application of jute bags for curing also produces positive results, indicating its practical suitability as a repair method for concrete structures exposed to fire incidents.
