Abstract. This study tried to compare the flexural strength of concrete made with riversand and quarry dust as fine sand was collected from Osogbo, Osun State, replaced at 0 at intervals of 10% with quarry dust gotten from Wasimi, Osun State, Common river sand is expensive due to the excessive cost of transportation from natural sources.
