* Objective :-
This test is intended to determine the specific gravity and absorption of coarse and fine aggregate samples.
* Introduction :-
The measured water absorption rate and specific gravity of aggregates is routinely used in design and construction of pavement materials and structures worldwide. The ability to measure the water absorption and specific gravity of aggregate materials with high degree of accuracy and repeatability in a short time is critical for engineers and practitioners interested in the properties of soils and aggregates.
Specific gravity is important for several reasons. Some deleterious particles are lighter than the good aggregate. Tracking specific gravity can sometimes indicate a change in aggregate mineral or physical properties of the material or possible contamination. For instance, if a quarry operation constantly monitors the specific gravity of its output aggregate, a change in specific gravity beyond that normally expected could indicate the quarrying has moved into a new rock formation with
