LOW DENSITY - Limestone having a density ranging from 110 through 135/lb/ft3 (1760 through 2160 kg/m3)..

MEDIUM DENSITY - Limestone having a density greater that 135 and not greater than 160 lb/ft3 (2160 through 2560 kg/m3).

HIGH DENSITY - Limestone having a density greater than 160 lb/ft3 (2560 kg/m3).

I would assume the low density is the closest match.
