Abstract: This research presents findings of cylinder tensile split and flexural strength behavior of concrete made using crushed glass as part of fine aggregates and sugar cane bagasse ash as part of cement. In trying to make industrial and agricultural wastes useful in the construction industry, 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 both tests, cylinder tensile split and flexural strength tests, showed that the strengths of the various mixes were lower as compared to the control mix. For the cylinder tensile split strength, the results showed that there was strength gain with increase in curing age but strength decrease with increase in composition of sugar cane bagasse ash in the mix. , the ratio of 7 days strength to 28 days strength for mixes containing 5 % and 10 % sugar cane bagasse ash with 30 % crushed glass content were 71.8 % and 70.1 % respectively, being higher than the control mix with 69.3 %. The flexural strength results showed that there was notable increase in strength, for mixes containing sugar cane bagasse ash at 5 % and 10 % with crushed glass percentage at 30 %, from 21.39 N/mm2 to 22.20 N/mm2 but still lower than the control mix, with 23.6 N/mm2. Generally, for the cylinder tensile split and flexural strengths, the higher the content of sugar cane bagasse ash in concrete mix, the lower the strengths of concrete, hence thats why the need for the steel reinforcement in the concrete mixes to increase their strengths.
