Density of Aggregate Bulk and Relative Density Civil

The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density = Mass of the Aggregate / Mass of equal volume of water. Key Features: Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m 3 (150 Overview. The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the fine aggregate specific gravity test.Coarse Aggregate Specific Gravity Pavement Interactive

Bulk SSD: Specific gravity measured under water saturated, surface dry conditions. Includes the volume and the mass of any water-filled voids. Used in Portland cement concrete mix design. Bulk Dry: Specific gravity measured under completely dried conditions. Includes the volume but not the mass of any void spaces within the aggregate Crushed stone is coarse aggregate that is mined and processed by mechanical crushing. It tends to be a very angular material and, depending on its other properties, can be well suited for use in HMA pavements. while the typical value for the specific gravity of granite is 2.65. 34 A Manual for Design of Hot Mix Asphalt with CommentaryChapter 4 Aggregates The National Academies Press

Normal weight aggregates have specific gravities in the range of 2.45-2.90, while aggregates below 2.0 are widely used as lightweight aggregate in structural lightweight concrete [48]. As shown inDesign of specific gravity factor of artificial lightweight aggregate

Fine Aggregates: Types, Properties & Uses in

It is used for concrete mix design and if not specified the specific gravity is taken as 2.7 because the specific gravity of most aggregates obtained from different sources falls between 2.6 and 2.8.. The current method of specific gravity and absorption of coarse aggregate testing is based on the AASHTO T 85 and ASTM C-127 standards. This approach involves the soaking of the coarse aggregate samples for 15h (AASHTO T 85) and 24. ± 4 h (ASTM C-127), and drying the aggregate to its saturated-surface dry (SSD) state with the aid of Determining the specific gravities of coarse aggregates

C127 Standard Test Method for Relative Density (Specific Gravity

Scope. 1.1 This test method covers the determination of relative density (specific gravity) and the absorption of coarse aggregates. The relative density (specific gravity), a dimensionless quantity, is expressed as oven-dry (OD), saturated-surface-dry (SSD), or as apparent relative density (apparent specific gravity).There is no specification for bulk specific gravity, but it is used to calculate other specified parameters such as air voids, VMA and VFA. Typical Values. Typical values for bulk specific gravity range from 2.200 to 2.500 depending upon the bulk specific gravity of the aggregate, the asphalt binder content, and the amount of compaction.Bulk Specific Gravity Pavement Interactive
