Bulk density and bulking of fine and coarse

The bulk density or unit weight of an aggregate is defined as mass of the aggregate per unit volume is expressed in kg/liter. The factors affecting bulk density of aggregate are 1.How densely the aggregates are packed. 2. particle size and shape 3.Greding of aggregate 4.Moisture content of aggregate.

Concrete Aggregates - Function, Properties

Aggregates are generally classified according to particle size, bulk density, or source sieve. Coarse aggregate is used to describe particles larger than 4.75 mm, and the term fine aggregate is used for particles smaller than 4.75mm. Fine aggregates contain particles in the size range 75 µm to 4.75 mm, and coarse aggregates from 4.75 to about 40 mm, except for mass concrete which may contain

Determination of bulk density of aggregates –

For a coarse aggregate, a higher bulk density means that there are few voids which are to be filled by the fine aggregate and cement. Thus, bulk density also depends upon the degree of packing. Procedure: Note down the dimensions and empty weight of the measuring container and compute its volume. For the determination of the loose bulk density, fill the container with the aggregate material

Coarse Aggregate Specific Gravity - Pavement

Specific gravity is a measure of a material's density (mass per unit volume) as compared to the density of water at 73.4°F (23°C). Therefore, by definition, water at a temperature of 73.4°F (23°C) has a specific gravity of 1. Absorption, which is also determined by the same test procedure, is a measure of the amount of water that an aggregate can absorb into its pore structure. Pores
