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.

2. POROSITY

bulk = bulk rock volume V matrix = volume of solid particles composing the rock matrix W dry = total dry weight of the rock r matrix = mean density of the matrix minerals. 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.
