Product Description

Void Content Apparatus for Coarse Aggregate

The void content of coarse aggregate value provides an indication of angularity, sphericity, and surface texture compared to other aggregates of the same grading. The test aggregate is allowed to free fall from the funnel of a cylindrical hopper into a cylindrical measure. Excess heaped aggregate is struck off, and the mass is measured. Uncompacted void content is computed as the difference between the volume of the cylindrical measure and the absolute volume of the coarse aggregate collected in the measure (based on bulk dry specific gravity as determined by AASHTO T85). Higer void content in samples of equal size gradation by this procedure indicates a combination of greater angularity, less sphericity, or rougher surface texture.
