Bulk Density of Coarse Aggregate: Usually used for coarse aggregate-weight concrete varies between 1200-1750 Kg/m 3 or 75 to 110 lb/ft 3. Bulk Density of Sand Kg /m³: Commonly used in normal-weight concrete is between 1520-1680 kg/m 3 (95-105 lb/ft 3). Density of Cement Concrete: 2.8 g/cm³. (gram per cubic centimeter)
Coarse Aggregate (Gravel): Coarse aggregate comprises particles with a size of more than 4.75 mm, as per IS (Indian Standard). When mixed with sand, cement, and water, coarse aggregate forms the main body of concrete. The maximum size of coarse aggregate used for concrete making is typically 20 mm.

The density of coarse aggregate used in concrete lies between 2.4 – 2.9 with a similar particle density about 2400-2900 Kg/m 3 (150-181 lb/ft 3). What Is the Density of Fine Sand? The density of sand (fine aggregate) is ranging between 1450 – 2082 kg/m 3 depending on different conditions like wet, dry, loose, dry-packed, and wet …
Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). ...

Density of water = 1000 kg/m 3 (62.4 lb/ft 3) Specific gravity of portland cement = 3.15 (typically assumed value) Slump. ... (1.5 inches) and the given fine aggregate fineness modulus of 2.80, the recommended volume fraction of coarse aggregate is 0.71. This means that the coarse aggregate should occupy 71 percent of the total volume.
The maximum possible size of the coarse aggregate that can be used, should not exceed 1/4th of the minimum thickness of the structural member or should be 5mm less than the minimum clear spacing between reinforcements in RCC structure. ... This increases cement content requirements. A maximum bulk density of aggregate is obtained when the ...
The purpose of the fine aggregate is to fill the voids in the coarse aggregate and to act as a workability agent. Fine aggregate: Size variation: Coarse Sand. 2.0mm – 0.5mm. Medium sand. 0.5mm – 0.25mm. Fine sand. 0.25mm – 0.06mm. Silt. 0.06mm – 0.002mm. Clay <0.002. Coarse Aggregate
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.

Calculating appropriate volume is critical to accuracy. In-bank soil, loose soil that has been excavated and fill soil that has been compacted, have different material densities and resulting load factors.
Aggregates having a size of more than 4.75 mm are said to be coarse aggregate. In another word; aggregates retained on a 4.75 mm sieve are coarse aggregate. Coarse aggregate provides the volume to the concrete. It is used as a filler material in concrete, roads, etc. 2. Origin of Coarse Aggregate
