aggregates—sand, gravel, crushed stone, and air-cooled blast-furnace slag—produce freshly mixed normal-weight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 5-3) are used to produce struc-tural lightweight concrete with a freshly mixed density

IS 456:2000 and IS 1343:1980 recommend that the nominal size of the aggregate should be as large as possible. 10-20mm size of aggregate is preferable. 6. grading of Combined Aggregate The relative proportions of the fine and coarse aggregates in a concrete mix are one of the important factors affecting the workability and strength of concrete.

The volume proportion in weight turns out to be. Cement : Sand : Aggregate (in Kgs) is 50 kgs : 115 kgs : 209 kgs (by weight) Water required for the mixture = 27.5 kgs. Total weight of concrete ingredients = 50+115+209+27.5 = 401.5 say 400 kg. Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum
