how to do rodding procedure of unit weight of aggregates

How to Calculate Unit Weight. Unit weight is one of a number of related basic physics terms that leads some students to confusion Also called specific weight, unit weight is in a family of terms that, loosely speaking, define and relate size (volume), amount (mass), concentration (density) and force (weight), along with specific gravity.

how to do rodding procedure of unit weight of aggregates

Then, knowing the volume of the measure and the weight of aggregates inside the measure, unit weight is calculated as weight over volume. The unit weight calculated by this procedure is called as "dry rodded unit weight" and if no rodding operation is applied, it is called as "dry loose unit weight".

Bulk Density and Void Percentage Test for Aggregates

The procedure provided in this article is based on the specification of ASTM standard ( ASTM C 29/C29M-17a). The bulk density or unit weight is the weight per unit volume (mass per unit volume or density). Voids in unit volume of aggregate are the space between particles in an aggregate mass not occupied by solid minerals.

The Effect of Aggregate Properties on Concrete

For mixture proportioning, the bulk unit weight (a.k.a. bulk density) is required. 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 ...
