Bulk Density by measurement For uniform rectangular refractory shapes the simplest way of measuring Bulk Density is by dividing Dry Weight by Bulk Volume which is calculated from measured dimensions. This is the recommended procedure for measuring Bulk Density of insulation bricks (containing >40 % true porosity) (ISO 5016 and ASTM C134).

The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density. The test is named in honor of Ralph R. Proctor ( de ), who in 1933 showed that the dry density of a soil for a given compactive effort depends on ...
