Rock density and porosity

 · Eq. 8 is a fundamental relation used throughout the earth sciences to calculate rock density. Given a porosity and specific fluid, density can be easily calculated if the mineral or grain density is known. Grain densities for common rock-forming minerals are shown in Table 2. The result of applying Eq. 9 is shown in Fig. 1.

It should be noted that the porosity does not give any information concerning pore sizes, their distribution, and their degree of connectivity.

Standard Weights for Crushed Rock Per Meter | Hunker

General Weights. Solid rock is estimated at 2.5 to 3tons per cubic meter. If rock is crushed into uniform sizes, the presence of open space between the particles causes the load to be lighter -- approximately 1.6 tons per cubic meter. Mixed sizes of crushed rock can range from 1.6 to 2.2 tons per cubic meter.

How to Measure Loose Density in the Field | |

STEP 2 – MEASURE THE LOOSE DENSITY OF THE MATERIAL. Fill the pail with materials from the site. DO NOT pack. Drop the pail to settle the material and eliminate voids. Strike off the material so it is level with the top of the pail. Weigh the filled pail.
