| Percentage Refusal Density |
| Percentage Refusal Density (PRD) is defined as the ratio of the initial dried bulk density of the sample to the final density (refusal density) expressed as a percentage, The sample bulk density is detemined by weighing in air and water, It is the heated in a split mould and compact ed to refusal using a vibrating hammer. The final density is obtained by weighing air and water |
