This research presents the study on the effect of recycled waste glass and red ash as a partial replacement of fine aggregate on compressive strength of concrete and workability. The mechanical properties by applying slump value and compressive strength were investigated. Experimental study carried out by conducting laboratory tests for concrete making materials (coarse aggregate, fine aggregate recycled crushed glass, red ash). The fine aggregate in each grade of concrete was replaced by recycled crushed glass and red ash 25 and 50% by volume. The control mix without incorporation of recycled crushed glass and red ash was prepared which was used as a reference for comparison of test results with those specimens produced by partial replacement. Generally, five concrete mixes were prepared including the control mix for C-25. Slump test was conducted for each concrete mix of fresh concrete. The properties of hardened concrete were studied by conducting compressive strength. The compressive strength test was carried out on the 7th, 14th and 28th days. The test results obtained by partial replacement were compared with the result of the control mix. In line with it the results, the one obtained by partial replacement of recycled waste glass in concrete specimens was slightly greater than that of the control mix by its compressive strength and higher workability. The compressive strength values of concrete with partially replaced red ash are close to the same as the normal concrete mix design with lower workability. Generally, the result reveals that recycled crushed glass and red ash can be used for structural concrete.
