Standard Test Method for The Determination of Bulk Density

The bulk density is more in compacted state as compared to the loose which shows that the bulk density greatly depends on the degree of compaction or how densely it is packed Usually increase in bulk density should be above 15 for coarse aggregate and should be below 15 for fine aggregate But in our results it is 1120 for fine aggregate and 1148 for coarse aggregate...
