    3 Aggregate Properties in

    There are aggregate particle voids, and there are voids between aggregate particles. As solid as aggregate may be to the naked eye, most aggregate particles have voids, which are natural pores that are filled with air or water. These voids or pores influence the specific gravity and absorption of the aggregate materials. Figure 3-1. Aggregate Specific Gravities. The voids within an aggregate

    What is bulk density and % of voids of fine aggregates

    How to calculate % of voids in fine aggregates. Voids:- the space between the fine particles of aggregate which was not occupied by solid material that is known as voids. And percentage of voids present in fine aggregate is calculated with the help of specific gravity of fine aggregate and their Loose bulk density by the following formula % of voids = {(Gs _R)/Gs}×100 . Where Gs = specific

    Bulk Density and Void Percentage Test for Aggregates

    The bulk density and void percentage of aggregate can be evaluated using standard test methods of applicable codes such as ASTM C 29/C29M-17a, IS: 2386 (Part 3) 1963, or BS 812-2:1995. The procedure provided in this article is based on the specification of ASTM standard ( ASTM C 29/C29M-17a).
