Scarcity of the construction resources such as money, labour, material, land and technology is creating a big chaos and so the nations are facing problems of low GDP’s. This research focuses on reuse of laboratory waste used aggregate and studying the mechanical properties of concrete with glass fiber and varying percentages of recycled aggregates. The study focuses on use of higher percentages of recycled aggregates and analyse optimum mix that can be used for structural applications by adding glass fibers without compromising the strength parameters. The behaviour of compressive, flexural and split tensile strength of concrete using glass fibers is studied where normal aggregates are partially replaced with recycled aggregates in proportions of 40%, 60%, 70%, 80% and 100% and usage of 0.25% glass fibers as addition by weight. After analyzing results it was observed that on addition of recycled aggregates strength decreases but mix designation CR80G0.25 (80% replacement of normal aggregates with recycled aggregates and addition of 0.25% of glass fibers) has least reduction 8.23% in compressive strength. Flexural and split tensile strength shows a reduction of 2.95% and 1.76% respectively for mix designation CR70G0.25 (70% replacement of normal aggregates with recycled aggregates and addition of 0.25% of glass fibers). This shows that Mix designation CR80G0.25 can be used for compression members like columns in buildings and Mix designation CR70G0.25 can be used in construction of beams and slabs.
