The structural defects of concrete pavements include low tensile strength, rigidity, brittle failure mechanism under stress, and more. This project replaces more costly fly ash with locally produced silica fume. Measurements of the flexure's compressive strength, stress-strain curves, and dynamic loading tests are all part of the experimental methodology. These experiments' outcomes showed that the fly ash and silica fume-infused ECC mixes had better tensile properties than ordinary concrete. The feasibility of the test was examined to support the results. But the ideal ratio turned out to be 25% cement mixed with silica fume. Consequently, using locally produced silica fume in Egypt's ECC with M30 grade concrete mix is more sensible. Because of its versatility, ECC is a material that shows promise for use in construction. In this case, it is applied as an overlay on firm pavements to minimize damage and make repairs easier.
