In order to be compacted, the mixture must have controlled workability. Typically, for dense-graded mixes, a lift thickness of 3 to 4 times the nominal maximum size (NMS) of the aggregate is needed. For example, a mix containing ½-inch NMS stone should be placed at a compacted depth of at least 1-½ to 2 inches.

The ratio of mass of an identical amount of water to a mass is known as the specific gravity or relative density of an aggregation. The relative density of the aggregates will be between 2.4 and 2.9, and the mass particle density of aggregate in kg/m3 will be between 2400 and 2900 kg/m3 (150 to 181 lb per ft3).

Based on their size, the aggregates are named as: Fine Aggregate; Coarse Aggregate; The material below 4.75 mm in size refers to fine aggregate. The percentage of all types of harmful matter in fine aggregate should not surpass 5%. Crushed stone dust or natural sand is the fine aggregate chiefly utilised in the concrete mix.

Since aggregates come in different sizes like 10mm, 20mm, and 40mm. The weight of each aggregate size in 1 CFT is not the same. Since the aggregates of 40 mm are of large size, there are large pores between each particle and it is filled with air. Due to this, the weight of the larger size aggregate would have been less in 1 CFT.

Fine aggregates usually consist of sand or crushed stone. Which is less than 4.75 mm in size. The coarse aggregate is usually between 4.75 mm and 37.5 mm. The use of mixed fines and coarse aggregates reduces the chance of void in concrete. The quality of concrete can be improved with the correct mix of aggregate. Bulk Density of Aggregate

Therefore, at the same air void level, mixes having larger nominal maximum aggregate sizes have more potential for high permeability than mixes of smaller nominal maximum aggregate sizes. Critical density values for different nominal maximum aggregate sizes are: 9.5 mm (0.375 inch) NMAS ˜ 7.5 – 8.0 percent air voids (92.0 – 92.5 percent TMD).
