Behaviour of carbon and basalt fiber reinforced concrete under split tensile and flexural strength testing

Fiber-reinforced materials have shown promise in recent decades as long-lasting materials with a wide range of applications. Instead of relying solely on widely used steel fiber, various reinforcements, such as carbon fiber and basalt fiber, have been introduced as alternatives. This study utilizes split tensile testing and flexural strength testing to examine how incorporating basalt fiber and carbon fiber impacts reinforced concrete. Six unique concrete samples, incorporating carbon fiber and basalt fiber reinforcement, are developed using the M25 and M35 control mixtures determined by compressive strength test outcomes. The research evaluates the Tensile Strength (TS), Flexural Strength (FS), deflection, and Modulus of Elasticity concerning stress and strain characteristics in cube, beam, and cylinder specimens for both carbon fiber and basalt fiber- reinforced concrete. The findings indicate that carbon fiber-reinforced concrete surpasses basalt fiber-reinforced concrete in terms of TS, flexural strength, and modulus of elasticity. Additionally, it is noted that the carbon-reinforced fiber based on the M35 mix demonstrates superior performance compared to the M25 mix-based carbon-reinforced fiber.
