classification of aggregates as per size and shape -coarse,coarse aggregate when the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. gravel, cobble and boulders come under this category. the maximum size aggregate used may be dependent upon some conditions..quality assurance for aggregates,aggregate passing through 40 mm sieve and retained on 20 mm sieve is 40+20/2 = 30 mm. now if the least dimension is less than18 mm (3/5 x 30 = 18 mm) then the aggregate is flaky. elongated aggregates are the aggregates whose length is 1.8 times of its mean dimension. if the mean dimension as shown above is say 30 mm then for a length above 54 mm (1.8x30mm) the aggregates will be classified as.density of cement sand and aggregate | cement density,density of sand (fine aggregate) is ranging between 1450 – 2082 kg/m 3 depending on different condition like wet, dry, loose, dry-packed, and wet packed. density of coarse aggregate. density of coarse sand is ranging between 1450 – 2082 kg/m 3 depending on different conditions like wet, dry, loose, dry-packed, and wet packed. density of cement.density of cement sand and aggregate | density of cement,: normal loose dry sand has a density of 1442 kg/m 3. density of coarse aggregate: coarse aggregate 20mm and 40mm ranging between 1200-1450 kg/m 3 (75 -90 lb/ft 3).
