Calculator bulk materials.

Calculator bulk materials - allows you to calculate the approximate mass of bulk materials by volume or volume weight.
Bulk density of the bulk material is its density in unconsolidated state.
It takes into account not only the volume of material particles (grains of sand or separate stones, gravel), but the space between them, thus bulk density less than usual.
The compaction of granular material, its density becomes more and ceases to be apparent.
A cement bag, a pile of rubble, or six cubic meters of sand in the back of a truck - they are all in unconsolidated state and have its bulk density.
Bulk density needed to link the volume and weight of bulk materials, as their prices can be specified as per tonne or per cubic meter.
Similarly, the number of these materials, for example, their proportions for concrete preparation, may be necessary, and in tons and cubic meters.fix error
