Abstract

This article deals with the measurement of the solid volumes and hence the packing density of elementary fractions of aggregates, a parameter used in modern methods for the optimization of granular mixtures. After reviewing methods for measuring solid volumes, two examples are presented to illustrate the relevance of the proposed method in elucidating the internal structures of aggregates, their morphological properties, and the state of the surfaces of their grains. The solid volumes data not only enhance standard characterization of aggregates but also underline the need to closely relate aggregate identification data with the geological history of the site where aggregates are extracted.

Keywords:
packing density or solid volume, aggregate, grain, granular mixtures, grain properties, standard characterization, geological texture, concrete
