Percentage Refusal Density ( Prd )
| BS 598 – 104 | |||
| Percentage Refusal Density (PRD) is defined as the ratio of the intial dried bulk density of the sample to the final density (refusal density) expressed as percentage. | |||
| The sample bulk density is determined by weighing in air and water. It isthen heated in a split mould and compacted to refusal using a vibrating hammer. The final density is obtained by weighing in air and water. | |||
