اقرأ المزيدThe density, from which the crushed stone is made, also influences the density. With the same volume - 1 m 3, the weight of the granite will be 2.6 tons. However, limestone due to impurities of quartz, dolomites, etc. - 2.7-2.9 tons. With the same weight, the volume will vary. As a result, large, unmilled rock takes up less space than recycled.

اقرأ المزيدThe 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.

اقرأ المزيدMany authors have measured the porosity of crushed-rock samples in granular form with the density method, assuming (probably incorrectly) a constant bulk density for different granular samples by using the value obtained from a whole rock sample (Klaja et al., 2015; Sun et al., 2016; Fu et al., 2019; Gaus et al., 2020).

اقرأ المزيدCalculating Density. Calculating density from mass and volume requires a simple formula: density equals mass divided by volume. So, if the measured rock mass equals 984.2 grams and the measured volume equals 382.9 milliliters, using the formula gives the equation: D=frac {984.2} {382.9}=2.57 D = 382.9984.2 = 2.57.
