Density of crushed stone: bulk and true density of
网页The quality of granite is judged from how far the resulting value of the density of crushed stone is from the density of granite 2.7 g / cm3 (or 2.7 kg / dm3). Too different from the "granite" value of the absolute density suggests that the crushed stone is not made of granite at all, but, say, basalt or, in general, secondary.
