The Relative Density Apparatus has a cylindrical mold of 3000-15000 cm3 and the vibratory table is 75mm x 75mm. The Motorized 230 VAC Relative Density Apparatus runs on singleThree phase and there is a guide sleeve with clamp that is meant for the molds. The surcharge base plate of the Relative Density Apparatus can bear the surcharge weight for 3000 and 15000 cm3, and the other components include handle for base plate, dial gauge holder, dial gauge (0.01 mm x 25 mm) and travel with extension piece calibration bar (75 x 300 x 3mm).
