Aggregate Size Effects: • As the maximum size aggregate increases, the amount of paste needed for a given slump decreases. • The maximum aggregate size used in a concrete mix is dictated by the size of the structural member and the spacing between reinforcing steel.

Bulk density of Aggregate. It is the weight of aggregate needed to fill a unit volume of the container. It helps to convert quantities by weight to by volume. It also indicates the aggregate grading and shape. Bulk Density = Weight of aggregate / Container of unit volume. Unit: Kg/m 3 or lb/ft 3. Essential Points

1. Scope. 1.1 This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.

Step-2: Calculate the weights of materials Required in 1 Cum Concrete. Density of Cement (loose) = 1440 kgs/cum. So weight of cement required = 1440 X 0.22 = 316.2 Kgs or 6.32 bags. Density of Sand = 1600 Kgs/cum. Weight of Sand required = 1600 X 0.44 = 704 kgs. Density of Aggregate = 1450 kgs/cum.
As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. Note, kg/cu.m divided by 16.02 = lbs/cu.ft
