Foamed Glass Aggregates are ultra-lightweight aggregates produced from postconsumer recycled glass. The aggregates have a highly frictional surface and combined with a low unit weight, inertness, high permeability, and insulting properties, foamed glass aggregate is ideal as a lightweight backfill.

The aggregates have a highly frictional surface and combined with a low unit weight, inertness, high permeability, and insulating properties, foamed glass aggregate is ideal as a lightweight backfill.

aggregates—sand, gravel, crushed stone, and air-cooled blast-furnace slag—produce freshly mixed normal-weight concrete with a density (unit weight) of 2200 to 2400

Classification 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 aggregates.
