Abstracts: Concrete is a composite material composed of coarse granular material (the aggregate or filler) embedded in a hard matrix of material (the cement or binder) that fills the space among the aggregate particles and glues them together.fly ash also known as flue-ash is one of the residues generated in combustion, and comprises the fine particles that rise with the flue gases. Ash which does not rise is termed bottom ash. High-performance concrete (HPC) is relatively new term for concrete that confirms to a set of standards above those of the most common applications, but not limited to strength. Glass-Fibre Reinforced Concrete (GFRC) is a material made of a cementitious matrix composed of cement, sand, water and admixtures in which short length glass fibres are dispersed. The inclusion of fly ash in glass fibre reinforced concrete reduces the environmental pollution and improves the workability and durability properties of concrete. The present paper outlines the experimental investigation conducted on the use of glass fibre with structural concrete and class F fly ash and also on strength aspect of concrete. In this project we find mechanical properties of M25 Grade Concrete like compressive strength and flexural strength. we used fly ash as a supplymetic material with replacement of cement at 15%,20% and 25%.we prepared cubes (150mm X 150mm X 150mm),beam (500mm X100mm X100mm)and casted at interval of 3,7,28 day.
