— A series of mix proportions for different ratio of cement:sand:quarry dust were prepared. Five types of mix proportions were practiced in the production of brick specimens were 1:10:0, 1:7.5:2.5, 1:5:5, 1:2.5:7.5 and 1:0:10 (Cement:Sand:Quarry Dust) and denoted as B1, B2, B3, B4 and B5 respectively.
Quarry Sand is produced in a variety of sizes which can be used for various purposes such as: Sharp sand (also called concreting sand) usually 5mm and finer Plastering sand; usually 1.5mm and finer. This is most suitable for bricklaying, block laying, mortar for rubble masonry (walls etc.) and for plastering (rendering) of walls and other surfaces.
