Bulk Density g/cc (Packed) - BDGC
This test procedure was employed in the Foresight Ceramic Database and now is available for those having an account at Insight-Live.com.
Accumulating test data using the variables defined in these procedures enables us to create tools that enable you to compare the physical properties of materials and recipes.
The measurement is done on the powdered material after settling. See ASTM C-29
1. Glass graduated cylinder 50 ml
2. Thin piece of rubber sheet
Place rubber sheet on the table. Weigh the clean dry glass cylinder. Add the powder in small amounts and tap the cylinder on the rubber sheet for each to pack it (do not press on it). Repeat until the level is at 50 ml. Weigh the cylinder again.
B = Weight of glass cylinder and sample
A = Weight of empty glass cylinder
Bulk Density (Kg/Liter or g/cc) = (B-C)/50
VAL - Value (V)
