Many types of research have been currently going to modify and improved the concrete properties by the addition of different types of materials. This Experimental investigation represents the Optimum use of the fibres with the concrete mixture and will help in achieving the desired results. This Experimental work shows the investigation on M35 grade due to the incorporation of glass fibres. In this Experiment, we used the glass fibres of Filament diameter 14 microns with aspect ratio 857 at various percentages like 0%,0.4%.0.8%,1.2%.1.6 by the weight of concrete on M35 grade of mix proportion (1:1.60: 2.96) with water cement ratio 0.45.
