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 … Webfreshly mixed concrete density, equilibrium density, and oven-dry density of lightweight concrete. Fresh Bulk Density (Freshly Mixed Concrete Density) is measured according to ASTM C138 using a ½ cubic foot measure. This is the highest value of density. This would be the basis of acceptance of lightweight concrete at the jobsite.
