Self-compacting concrete (SCC) is a highly flow-able type of concrete that spreads into the form without the need for mechanical vibration. This study explores the feasibility of using quarry stone dust and glass cullet as partial replacement for fine aggregate in the production of SCC. This project was done to assess how SCC will behave with quarry stone dust and incremental percentage of glass cullet in 0%, 10%, 20% and 50%. Making use of the mix design the samples were cast and the necessary test such as sieve analysis, flexural strength test, compressive strength test, bulk density water absorption and slump test were carried out on three samples per mix to get the average results. The result obtained showed that the mix of quarry stone dust and 20% of glass cullet has the highest compressive strength at 17.01 ,21.09 , 23.23 for 7, 14 and 28 days curing period respectively than other mix, the sample with the highest flexural strength was also the 20% glass cullet mix sample at 3.73 ,4.53 and 4.8 for 7,14 and 28 days curing period. The water absorption rate of samples when compared had a decrease with the amount for glass cullet percentage available in the mix of with the lower was at 50% of glass cullet at 4.11% and 4.39% at 2 and 24 hours respectively at 28 days. This research validates the use of quarry stone dust and glass cullet to improve workability, compressive strength, flexural strength and also water absorption rate which is necessary to predict the long-term performance of the concrete.
