This research examines how the mechanical properties of fibre-reinforced concreteare affected by the presence of steel fibres and silica fume. The study employed three varying volumes of steel fibres (0.54%, 0.90%, and 1.26%) with two distinct aspect ratios (32 and 52). Additionally, three different silica fume contents (6%, 12%, and 18%) were incorporated intothe mix. This study comprehensively assessed various attributes of concrete mixes, encompassing compressive strength, splitting tensile strength, flexural strength, and modulus of elasticity. The results demonstrated that including silica fume in plain concrete led to enhancements in mechanical and durability properties. Furthermore, incorporating steel fibres contributed to the improved mechanical characteristics of the fibre-reinforced concrete. The investigation pinpointed the optimal proportions for concrete's compressive strength and modulus of elasticity to be 0.90% steel fibre and 12% silica fume. Similarly, the ideal ratios for splitting tensile and flexural strength for fibre-reinforced concrete were 1.26% steel fibre and 18% silica fume. Attaining the desired strength and durability in concrete necessitates themeticulous incorporation of optimum proportions of silica fume and steel fibres. This processguarantees the manifestation of all essential characteristics in the final product. [ABSTRACT FROM AUTHOR] |
