Study on Strength and Durability Properties of Polypropylene and Carbon Fiber Reinforced Concrete Composite

Abstract

Abstract: Concrete is the most widely utilized “manmade” material globally for construction in many developing countries in all types of civil engineering works. Also, concrete is an environmental - friendly material and in areas of growing environment – related awareness that is of prime importance. The weakness of concrete is due to the presence of micro cracks at mortar aggregate interface. To overcome the existing problems addition of fibers in the concrete has been come in to practice. In fiber reinforced concrete the fibers are added to the concrete mix so that those are discontinuous fibers will be uniformly distributed in the mix and improve the concrete properties in all directions. In this research paper, an attempt is made to use fibers only .The experimental investigation consisting of casting and testing of compression tests were conducted on 150x150x150mm cube and 150mmx300mm, cylindrical specimens using test method that gave the complete compressive strength, split tensile test using with and without fiber.The strength and durability properties are carried out for various mix designations and compared with normal conventional concreteIn present project work M25 grade considered and the polypropylene (PP) fiber at 0.5,1 ,1.5 ,2 and 2.5% volume fractions and carbon fibers at 1, 1.5, 2,2.5 and 3% volume fractions are introduced into fiber‐reinforced. Based on the results will find the superior crack resistance, improved tensile strength. The proposed sample will be tested at 7 days, 21 days and 218days age of curing. These results will show whether the FRC is suitable for proper confinement or not for structures subject to extreme load conditions
