Concrete is one of the mostly widely used construction material in today’s world. Cement being one of the essential constituent of the concrete. Concrete mainly suffers from limited ductility, low tensile strength, and slightly resistant from cracking. With increase in coal based thermal power projects there is increase in production of fly ash which is a waste material and the disposal of this fly ash is hazardous to environmental if it is not disposed well. The addition of glass fibres to concrete considerably increase structural characteristics such as flexural strength, impact strength, tensile strength and ductility. In this study addition of glass fibre and fly ash of class -f as cement replacement in production of concrete with percentage ranging from 0%, 0.5%, 1% and 2% of glass fibre and 20% replacement of fly ash. The main objective of this project with M30 ratio of 1:1.75:2.03. Due to addition of glass fibre and fly ash the compressive strength, split-tensile strength and flexural strength was increased due to pozzolonic action of fly ash with glass fibres. The strength attained maximum at 20%, 2% of fly ash and glass fibre respectively.
