Abstract (en)
[origin: WO2017016550A1] The invention relates to a method and a device for sintering sand. The problem addressed by the invention is that of using energy-saving sintering to make it possible to use desert sand, having round grains and evenly distributed among the grain fractions, for use as a building material, in particular as an aggregate. The problem is solved by providing a focusing device (3) for thermal-energy rich radiation (2) in order to create at least one focal point (5) on the surface of a bulk sand (10) and a positioning device (6) for continuous relative movement between the focal point (5) and the sand (10). The problem is also solved via a use of desert sand as an aggregate for a component (12), characterised in that, by sintering, obtained grain bonds (11) of desert sand (10) are incorporated in a matrix material (13) as an aggregate.
