Expanded clay 0 / 4mm (bulk density 460-700 kg / m3) - 600 m3, expanded clay fraction 10 / 16mm (bulk density 280-400 kg / m3) - 3 000 m3 for 2018 according to stb en 13055-1-2003 (en13055-1) and stb en 14063-1-2007 (en14063-1) 3,600 cu.
Bulk density can be measured by simply filling a calibrated container and weighing it.
The reduction of moisture content for the bulk density determination was monitored using a scale with 0.01-g resolution, while the other physical properties were monitored using a scale with 0.001-g resolution, through the gravimetric method (mass loss), until the grains reached the final moisture content of 0.073 [+ or -] 0.008 decimal d.b.

In agricultural soils, tillage affects soil aggregation and bulk density by breaking up root systems and large aggregates and exposing organic matter to decomposition and loss.
As [epsilon] and [rho] are reciprocal and the relation between them depends on the (solid) particle density, the aim of this study was to analyze the effect of initial bulk density and particle density on the relation between [sigma]p and Ic with [epsilon] and [rho], theoretically, and experimentally in compression curves of an ultisol and an oxisol.
A high expansion ratio and low bulk density was achieved by applying a relatively high mold temperature (45, 60, 65, and 70[degrees]C in this study).
The impacts of skidding on the surface soil layer (0 cm - 10 cm depth) were examined using dry bulk density, forest floor removal and rut depth in comparison to the undisturbed area at the different levels of slope and traffic.
These involve changing the way material flows inside the silo, particularly increasing the friction between the material and the silo wall, combined with increasing the silo strength to be able to resist any high transient stresses and the higher bulk density of PET.
Transportation by truck-trailer is a large portion of the total delivered cost of comminuted forest harvest residues, and the load quantity is dependent on the moisture content and dry bulk density of the residues.
