The following calculations are used in this test:

 

Bulk Specific Gravity

 

SGbulk = A / (B - C)

 

where,

SGbulk        = Bulk specific gravity

A        = Mass of dry specimen

B        = Mass of saturated surface-dry specimen in air

C        = Mass of specimen in water

 

 

Density

 

ρ = SGbulk * ρw

 

where,

ρ        = Density

ρw        = Density of water at 25°C (0.9970 g/cm3)

 

 

Water Absorption

 

Absorbed water (%) = 100 * (B - A) / (B - C)
