rodded density of aggragate
Classification of Aggregates
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.

volume of the container to yield the dry rodded unit weight in terms of weight per volume such as pounds per cubic foot. By knowing the dry rodded unit weight of a nominal maximum size coarse aggregate and the fineness modulus of the fine aggregate, the weight of the coarse aggregate needed per unit volume of concrete mix can be estimated.

The Effect of Aggregate Properties on Concrete
The bulk density measures the volume that the graded aggregate will occupy in concrete, including the solid aggregate particles and the voids between them. Since the weight of the aggregate is dependent on the moisture content of the aggregate, a constant moisture content is required. This is achieved by using OD aggregate.
