Abstract - The objective of this experimental investigation is to improve the mechanical characteristics and durability of concrete mixes by examining the synergistic impacts of silica fume and synthetic fibres. The goal of the research is to optimise the design of the concrete mix by methodically adjusting the amounts of synthetic fibres and silica fume. Because of its pozzolanic reactivity, silica fume is projected to boost the concrete's compressive strength and endurance, while synthetic fibres help to improve the material's tensile strength and resistance to cracking. Compressive strength, flexural strength, and durability evaluations are just a few of the demanding tests that are part of the experimental program to see how well various concrete combinations work. The goal of the research is to find the ideal ratio of silica fume to synthetic fibres so that strength and durability are balanced.The results of this study not only advance our basic knowledge of the interactions between silica fume and synthetic fibres in concrete, but they also provide engineers and other construction industry professionals with useful information for improving the performance of concrete in practical applications.

Key Words:  Mechanical Characteristics, Durability of Concrete, Silica Fume, Synthetic Fibres, Compressive strength, Flexural strength.
