Experimental study on the thermal properties of fiber reinforced concrete (TPFRC)

Abstract

Fiber-reinforced concrete (FRC) has recently sparked interest in the scientific community because of its superior qualities over regular concrete. Traditional concrete must be strengthened and updated to bear enormous loads and overcome concrete faults such as cracking, swelling, and shrinking. The use of FRC is advantageous in industrial, commercial, and strategically significant buildings that are prone to fires. The experimental results of the study and comparison of thermal characteristics and temperature-dependent mechanical properties of Polypropylene, Steel and Hybrid (steel + Polypropylene) fiber-reinforced concrete are presented in this project. The effect of employing Polypropylene, Steel and Hybrid fibers (steel + polypropylene) in the proportions given and fluctuation in strength parameters, and qualities shown owing to heating at different temperatures were investigated in this study. The thermal properties of the non-metallic and metallic fibers were studied through experimentation and results were concluded. It can be recommended from the experimental investigation that the usage of fiber-reinforced concrete is advantageous for ensuring the safety of important industrial buildings which are often exposed to high temperatures. Polypropylene can be employed in cases which are subjected to unfavorable environmental conditions, impact damages, and surface abrasion.
