The parameters involved in Fig. are max. size of aggregate, the water content, degree of workability and the percentage of fine aggregate passing through 600 micron sieve. Knowing the proportion of fine aggregate from Fig., the weight of fine aggregate may be obtained by multiplying the total weight of aggregate by this proportion.

Density of Aggregate
Key Features: If the volume is unit then, Bulk Density= Mass. Unit in kg/m 3 or lb/ft 3. In this definition, the volume is that contains both the aggregates and the voids between aggregates particles.
