COMPRESSION OF TENSILE STRENGTH FIBER REINFORCED CONCRETE WITH DIFFERENT TYPES OF FIBERS

Abstract

Considered superior in mechanical properties and durability when compared to ordinary concrete, fiber-reinforced concrete has always been appealing in the construction business. This paper includes glass fiber and steel fibers to see how compressive strength, a key factor for tensile strength, varies in concrete. Many concrete specimens were cast with varying quantities of glass fiber and steel fiber but maintaining the same mix design of concrete. The compressive strength was tested at days 7, 14, and 28 of curing. It was seen that both fibers enhanced the compressive strength of concrete; however, the improvement brought about by steel fibers was more appreciable because steel fibers can carry loads better and have a better bonding mechanism with the cementitious matrix. Glass fibers are not as efficient when it comes to augmenting compressive strength but do increase ductility and resistance to cracking and corrosion. This finding implies that the role of fiber type selection must be based on the structural requirements and environmental conditions, with steel fibers being suitable for high-strength applications and glass fibers being more useful in more aggressive environments and in cost-limited projects. This study presents practical information for the optimum use of fibers in concrete for improved performance and durability.
