Bulk density - Wikipedia

The bulk density of soil depends greatly on the mineral make up of soil and the degree of compaction.The density of quartz is around 2.65 g/cm 3 but the (dry) bulk density of a mineral soil is normally about half that density, between 1.0 and 1.6 g/cm 3.In contrast, soils rich in soil organic carbon and some friable clays tend to have lower bulk densities (<1.0 g/cm 3) due to …


Ball Bulk Density. Low density media can be used for soft and brittle materials. Hard materials required high density media. Rose and Sullivan (1961) estimated the required media density (Ï B) using the expression: Ï â†"B = (0.016Ï â†"Sâ†'2 + 20Ï â†"Sâ†'2) â†'0.5 – 0.4Ï â†"s


The same excavation in feet: Excavated area is 200 feet long 20 feet wide and 2 feet deep with a listed swell of 40% for the material. Bank volume = 200 * 20 * 2 = 8000 ft³. Convert 8000 ft³ to yd³ = 8000/27 = 296 yd³. Loose volume = 296 * 1.4 = 414 yd³. (Calculation is based on the material being of similar consistency.

Density logging - Wikipedia

Density logging is a well logging tool that can provide a continuous record of a formation's bulk density along the length of a borehole.In geology, bulk density is a function of the density of the minerals forming a rock (i.e. matrix) and the fluid enclosed in the pore spaces.This is one of three well logging tools that are commonly used to calculate porosity, the other two being sonic ...


PC to calculate the volume and generating contour map by using Civil CAD software. Bulk density is determined from the average field test results of an individual stockpile. The mass of the stockpile is calculated by multiplying the volume by the density. Time to complete measurement for each pile will vary according to the shape and profile.

Density Calculator p = m/V

V = volume. The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume. Along with values, enter the known units of measure for each and this calculator will convert among units.

Bulk density is the weight of soil in a given volume. Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. Bulk density can be used to calculate soil properties per unit area (e.g. kg/ha).


the bulk density of rock core samples typically encountered in the mining industry. The main problem in determining the bulk density of rock core is obtaining an accurate estimate of the rock core's total volume. The research investigated four common techniques used to measuring the bulk density of materials.


Jun 20, 2013· RE: Bulk density limestone stockpile. fattdad (Geotechnical) 21 Jun 13 10:34. the specific gravity of calcite is 2.71. If there were no voids in the broken rock the unit density of limestone would then be 169 pcf. If there are 30 percent voids (guess for broken rock), the dry density would then be 118 pcf. So, 120 is a resonable value.
