ASTM-C29

Loose Unit Weight & Voids in Agg / Loose Bulk Density

Applicability: ASTM C29 is a standard test method for determining the bulk density (unit weight) and voids in aggregate, which is used for both fine and coarse aggregates, and is important for concrete mixture proportioning and purchase agreements.

Purpose: The test method also allows for the calculation of the percentage of voids (empty spaces) between the aggregate particles within the bulk density. Bulk density values are crucial for selecting the correct proportions of aggregates in concrete mixtures.
