The density of gravel

The 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.

Density of crushed stone: bulk and true density of crushed stone …

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.

Sandstone. 2.2–2.8. Shale. 2.4–2.8. Slate. 2.7–2.8. As you can see, rocks of the same type can have a range of densities. This is partly due to different rocks of the same type containing different proportions of minerals. Granite, for example, can have a quartz content anywhere between 20% and 60%.

Porosity measurement of granular rock samples by modified bulk density

Many 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).

How to Find the Density of a Rock | Sciencing

Calculating 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.

Gravel Calculator: How Much Gravel Do You Need?

Step 2: Convert to Cubic Yards. Gravel is often sold by the cubic yard, so you'll need to convert your measurements from cubic feet to cubic yards. Divide the cubic feet value by 27. For instance, in the circular pond example, you'd need: 135.3 cubic feet / 27 = approximately 5.01 cubic yards of gravel.
