WebClassification of Aggregates. The variability in density can be used to produce concrete of widely different unit weights, see Table (1). The most common classification of aggregates on the basis of bulk specific gravity is lightweight, normal-weight, and heavyweight … WebHeavy weight aggregates are used for concretes with higher than normal densities (e.g. those used for radiation shielding or ballast purposes). Generally these are naturally occurring dense rocks such as barytes, magnetite and other heavy metallic ores. Alternatively, metal aggregates, e.g. steel or iron shot, may be used.
