Abstract: This research work investigated the workability and compressive strength behavior of concrete made using crushed glass as part of fine aggregates and sugar cane bagasse ash as part of cement. The sugar cane bagasse ash (SCBA) was used to partially replace cement at 0 %, 5 %, 10 %, 15 % and 20 % and crushed glass used to partially replace river sand at 30 % by mass. The slump was maintained at 10-25mm for vibrated concrete and design mix ratio of 124 at water cement varying proportion of 0.50-0.65 was also used. The best results of concrete were achieved for 10 % replacement of cement with SCBA and 30 % crushed glass replacement of river sand. The 28 days compressive strength rose to 22.03N/mm2 at 0.61 water cement ratio, but lower than the control concrete strength of 23.06 N/mm2, then started dropping. However, only 51.6 % of the 28 days strength had been achieved at 7 days for the mix, which was lower than the control mix of 70 % at 28 days. This type of concrete is suitable for constructions of lightly loaded beams like lintels, and slabs of class 20 concrete mix design.
