Calculations

The particle density on an oven-dried basis (in Mg/m3) is calculated from the formula:

D/A-(B-C)

The particle density on a saturated and surface-dried basis (in Mg/m3) is calculated from the formula:

A/A-(B-C)




The apparent particle density (in Mg/m3) is calculated from the formula:

D/D-(B-C)

The water absorption (as % of dry mass) is calculated from the following formula:

100 (A-D)/D

Where

A       is the mass of the saturated surface-dry sample in air (in g);

B       is the mass of vessel containing sample and filled with water (in g);

C       is the mass of vessel filled with water only (in g);

D         is the mass of the oven-dry sample in air (in g);
