Mass, Weight, Density or Specific Gravity of Bulk …

The specific gravity of all other materials are compared to water as a fraction heavier or lighter density. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic metre) (see table below) As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft ...

7 LAB TESTS ON AGGREGATE TO CHECK QUALITY …

The specific gravity and water absorption of aggregates are important properties that are required for the design of concrete and bituminous mixes. The specific gravity of a solid is the ratio of its mass to that of an equal volume of distilled water at a specified temperature. Because the aggregates may contain water-permeable voids, so two measures of specific gravity of aggregates are used:

This is because the flocs aggregated using high-specific gravity ballasts (ballast C) show faster settling (105mh-1 compared to 99mh-1 of ballast D at G value: 1250s-1) despite a comparatively smaller ballast fraction (2.3% compared to 3.5% of ballast D at G value: 1250s-1) in the floc aggregate. Overall, the observations of average ballast induction at various G values agree with the ...

Density of Aggregate - Bulk and Relative Density - …

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 (150-181 lb/ft 3). Here, for coarse aggregates, the standard test ...

What is the unit weight of gravel? | AnswersDrive

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.
