The raw material for the silica brick production is the high-silica sand (92-95% of dry mixture) and the lime (5-8%). Structural capabilities of the brick directly depend from the degree of activation of SiO2 and mixing uniformity of components. According to this fact, application of ABC for the treatment of dry mixture by the reason of mixing and activation of components is of the utmost interest. We have investigated the ways of sand-lime mixture activation by spillage of material through the vortex layer of the unit ABC-100. It is interesting to note that, in this short-duration treatment of the mixture (mixture particles locate into the vortex field for a fraction of a second) the grinding of the sand and the lime is not observed. The degree of activation can be determined by the changing of mechanical properties of obtained silica brick. As you can see from the table by the short-duration treatment of the mixture you can increase the durability of the silica brick in 3,5 times. Obviously, similar processing sand-lime, lime-ash and lime-silica mixtures leads to an marked increase of the mechanical properties of silicate concrete, which are widely used in prefabrication.
