• This apparatus facilitates the determination of the average density, relative density (specific gravity), and absorption rate of coarse aggregate particles. The density measurements can be expressed in terms of oven-dry (OD), saturated surface-dry (SSD), or apparent density states.
• The system comprises a robust, high-rigidity frame that ensures stability and durability during testing procedures.
• The lower section of the frame features a moving platform designed to hold a water tank, allowing specimens to be weighed both in air and while submerged, as required by standard testing methods.
• A stainless steel wire basket with dimensions of 200 mm in diameter and 200 mm in height, constructed with 3.35 mm (No. 6) mesh, is provided for holding aggregate samples during testing.
• The frame is designed to accommodate an electronic balance equipped with an under-hook facility, enabling precise measurement of specimen weights in different states.
