Plain concrete possess very low tensile strength and little resistance to cracking. Internal micro cracks are inherently present in concrete and its poor tensile strength is due to propagation of such micro cracks. Fibres when added in certain percentage in the concrete improve the strain properties as well as crack resistance and flexure strength. Mainly the studies and research in fibre reinforced concrete has been devoted to steel fibres. In recent times, glass fibres have also become available, which are free from corrosion problem associated with steel fibres. The present paper outlines the experimental investigation conducts on the use of glass fibres with structural concrete. Therefore we are able to cast various test samples (normal & fibre reinforced concrete) with an M30 mix design. Fibres of length 12mm and having a diameter of 14μ are added in various proportions (0.5 %, 1%, and 1.5% by weight of cement) and the strength is compared. Cubes, cylinders and beams are casted and the Compressive strength, Split tensile strength and Flexural Strength are compared.
