The sand is divided into many varieties, which are determined by different grain composition, its density, heat conductivity, porosity, particle size, and other factors. Its density can be bulk, as well as true. In the latter case, you can draw an analogy with the physical density of any solid substance. In other words, all kinds of voids are not taken into account in the true density of building sand in Dnepropetrovsk. If we are talking about the bulk density of this material, then this parameter is calculated with the inclusion of all pores that occupy the space between the particles.
