Density of Aggregate Bulk and Relative Density Civil

The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3 (75-110 lb/ft 3). Here, the Standard test method for determining the bulk density of aggregates is given in ASTM C 29 (AASHTO T 19). [2] Relative Density of Aggregate [1] The relative density (specific gravity) of an aggregate

Aggregate Base Density Data Earthwork/grading

Jun 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).
