Specific gravity is easily calculated by determining the densities by the displacement of water. All aggregates contain some porosity, and the specific gravity value depends on whether these pores are included in the measurement. There are two terms that are used to distinguish this measurement; absolute specific gravity and bulk specific gravity. Absolute specific gravity (ASG) refers to the ...

The specific gravity of aggregates normally used in construction ranges from about 2.5 to 3.0 with an average value of about 2.68. Specific gravity of aggregates is considered as an indication of strength. Material having higher Specific Gravity is generally considered as having higher strength. Water absorption of aggregate is a measure of porosity. This value is considered as a measure of ...

The object of the experiment is to determine the Specific Gravity & Water Absorption of Fine Aggregate by using Pycnometer or Specific Gravity Flask. Specific Gravity is the ratio of the mass of a unit volume of soil at a stated temperature to the mass of the same volume of gas-free distilled water at a stated temperature.

Though higher specific gravity of aggregate is considered as an indication of its high strength; it is not possible to judge the suitability on this basis alone without finding other mechanical properties like aggregate abrasion value etc. Water absorption is a measure of porosity of aggregates and its resistance to frost action. Higher water absorption means more pores hence aggregate will be ...

For large-scale concreting operations without complex reinforcement, large aggregates of size 80 mm, 40 mm, 20 mm are used. For the simple construction of residential or other buildings, 20 mm is the maximum size that will be used. Aggregates are graded in a concrete mix design and the ratio of each size is determined using grading curves, charts, tables, or other methods. Advertisement. video ...

Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water, at a temperature of 73.4°F (23°C) has a specific gravity of 1. Specific Gravity is important for several reasons. Some deleterious particles are lighter than the good aggregates. Tracking specific gravity can sometimes ...

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 ...
