A Study on Partial Replacement of Cement with Steel Fiber and Glass Fiber for M30 Grade Concrete

This study explores the effect of incorporating steel and glass fibers on the compressive strength of M30 concrete. Steel fibers and glass fibers were added to the concrete mix in varying proportions (1%,1.5%,2%,2.5% by volume). The compressive strength of the fiber-reinforced concrete was evaluated at 7 and 28 days. The results indicate that the addition of steel fibers significantly enhances the compressive strength of M30 concrete with a maximum increase of 23.5% at 1.5% steel fiber content. Glass fibers also showed a notable improvement in compressive strength with a maximum increase a notable 17.2% at 1.5% glass fiber content. The study concludes that the use of steel and glass fibers can be an effective way to enhance the compressive strength of M30 concrete. The research methodology involves the preparation of M30 grade concrete specimens with varying fiber content for each type. The concrete mixes are cured and subjected to a series of standard tests to evaluate their strength and durability. The study aims to understand the influence of steel fibers and glass fibers on the overall performance of M30 grade concrete and to identify the optimal fibers dosage for enhanced structural properties
