TEST : Bulk density of coarse aggregate

MUST be based on the experimental data and need to be compared with the range of value from text/ publication.

1. What is the significance and use of bulk density. ( I have attached the test result) if you need further info let me know ... thank you

Answer:-

Significance of bulk density of aggregate:-

(1) Bulk density of aggregate is the mass of aggregates required to fill the container of a unit volume after aggregates are batched based on volume.

(2) Bulk density depends on how densely the aggregate is packed.

(3) Bulk density depends on the size and shape of particles.

(4) For coarse aggregate a higher bulk density means that there are few voids which are to be filled by the fine aggregate.

Uses of bulk density:-

(1) Bulk density indicates the compactive effort required to compact the concrete.

(2) Bulk density indicates the percentage air voids present in the aggregate material.

Bulk density of coarse aggregate = 1560 kg/m³
