Abstract

Fire accidents are one of the frequently occurring disasters which can take place anywhere at any time without any warning. They can be fatal and inflict higher risks on human lives, properties and environment. In order to improve the resistance of structures against fire, fire safety should be considered from the preliminary stages of design and material selection. Concrete and structural steel are primary construction materials in world. Concrete is known to have good thermal resistance when compared to steel. If concrete is subject to elevated temperatures, the separation of concrete masses occur, giving rise to a phenomenon known as “spalling” which further leads to weakening of the cross sectional area of the concrete members thereby decreasing their resistance to service loads. In the present scenario where the pace of urbanization is at its peak, fire accidents in building is a crucial factor of consideration. During fire, safety of inhabitants and structural integrity are equally important and is ought to go hand in hand.. In such a situation use of fire resistant concrete can prove to be fruitful. This project investigates the effect of fire on polypropylene fiber and coconut husk fiber reinforced concrete. In the present era the use of fiber reinforced concrete is no more an innovation. But this project explores the effectiveness of sustainable fibers such as polypropylene fiber and natural coconut husk fiber on the fire resistance on concrete. The aim is to improve the problems of concrete spalling and deterioration by the addition of polypropylene fibers and natural coconut husk fibers in concrete. Several samples of fiber reinforced concrete cubes are casted by partial replacement of fine aggregate with these fibers and are tested for fire resistance and strength yield. These test results are compared with conventional concrete samples and inferences formed.
