- what is the density of coarse aggregate

thanks for ask bro Coarse Aggregate in general should consist of natural occurring stones (crushed, uncrushed or broken), riverbed single or pit gravel. It should be hard, strong, dense, durable, and clean. It must be free from veins, adherent co...

MoreMost aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m 3 (150-181 lb/ft 3). Here, for coarse aggregates, the standard test method has been explained in ASTM C 127(AASHTO) and for fine aggregates, the standard test method has been explained in ASTM C 128 (AASHTO).

MoreMost of the aggregates possess a relative density within 2.4 – 2.9 with a similar particle density about 2400-2900 Kg/m 3 (150-181 lb/ft 3). Hereabouts, for coarse aggregates, the standard test process has been described in ASTM C 127(AASHTO), and for fine aggregates, the standard test practice has been described in ASTM C 128 (AASHTO).

MoreAug 31, 2020 If the coarse aggregate contains a substantial quantity of material finer than the 4.75-mm sieve (such as for Size No. 8 and 9 aggregates in Classification D 448), use the 2.36-mm (No. 8) sieve in place of the 4.75-mm sieve.

Bulking of fine aggregate 3. The bulk density or unit weight of an aggregate is defined as mass of the aggregate per unit volume is expressed in kg/liter.

MoreJul 04, 2020 Usually, the bulk density values for fine or coarse aggregate is in the range of 1350 to 1650 kg per meter cube. Importance Of Bulk Density Of Aggregate. Bulk density of coarse aggregate under the dry rodded condition is called its dry rodded unit weight. It is an extremely important value that we used in concrete mixture proportioning.

MoreSpecific Gravity/Relative Density. It is the ratio of the density of the aggregate material to the density of the gas free distilled water at a standard temperature (i.e. 4 o C). The relative density is a dimensionless quantity and is expressed as oven dried, saturated surface dry and apparent. Oven Dried Specific Gravity

MoreThe design will consist of three aggregate sources, one coarse and two fine. The coarse aggregate will consist of No. 8 aggregate and the fine aggregates will be No. 10 aggregate and natural sand. In addition to using coarse and fine aggregates the mix design technician should account for plant breakdown by incorporating

MoreJun 09, 2005 The (150-180) density data comes from a "Design and Control of Concrete Mixtures" book and appears to refer to the "particle" density of aggregate. However, since the aggregate is made up of particles, it is reasonable that the compacted density of the aggregate is between (150-180 lb/ft^3).
