Experimental Study on Fiber Reinforced Concrete by Using Carbon Fiber in Different Aspect Ratios

This experimental study investigates the effects of varying aspect ratios of carbon fiber on the performance of fiber reinforced concrete. The research aims to determine how different aspect ratios influence the mechanical properties, such as compressive strength, splitting tensile strength, and flexural strength of the composite material. The study involves preparing concrete specimens with varying proportions of carbon fibers, ranging from short to long aspect ratios and deals with experimental investigations carried out on M20 grade of concrete reinforced with carbon fiber dosages of 5 cm in length & 1 cm in width, 2.5 cm in length & 0.5 cm in width by volume of concrete. Due to its improved mechanical characteristics and increased durability, fiber reinforced concrete (FRC) has attracted a lot of attention in the building industry. Carbon fiber stands out among the numerous kinds of reinforcing fibers for its remarkable strength-to-weight ratio and resistance to corrosion. This experiment looks at how adding carbon fibers to concrete at different ratios affects the strength and durability of the structure. Fibers are used to improve the properties of concrete. The fibers were added at the volumes. Adding carbon fiber to the concrete changes in the mechanical properties of concrete. Hence, we expect the Compressive strength of CFRC increases with increasing fiber content up to a certain percentage, after which increasing fiber content becomes unbeneficial.
