Abstract: A process for the manufacturing of a cement substitute may include: mixing an alkaline aluminosilicate containing material with at least one aluminosilicate hydrate containing material, and heating the thus obtained mixture to a calcination temperature of below 800° C. to form a calcined product comprising a reactive amorphous phase having the alkali ions bound therein. The process may further comprise a step of cooling the calcined product to a desired temperature. A cement substitute is obtainable by this process. The cement substitute includes a reactive amorphous phase of co-calcined alkali aluminosilicate containing material and aluminosilicate hydrate, containing material having alkali ions bound therein. The alkali ions are preferably sodium ions.

Abstract: The present invention relates to a device (1) for sorting powder particles into ranges of particles according to one or more of a density, size and/or shape of the particles, wherein the device (1) comprises a particle sorting chamber (2) with at least one sloping side wall (3), which side wall (3) slopes from a lower part (4) of the sorting chamber (2) towards an upper part (5) thereof, wherein the lower part (4) of the sorting chamber (2) is larger dimensioned than the upper part (5), wherein at the upper part (5) of the particle sorting chamber (2) an inlet (6) is provided for supplying a flow of the powder particles to be sorted to the sorting chamber (2), wherein a particle outlet (7) is provided in the upper part (5) of the sorting chamber (2) for conducting sorted particles from the sorting chamber (2) through a duct (8) to at least one particle sedimentation classifier (9), wherein in the lower part (4) of the sorting chamber (2) means (11) are provided for generating an upward rotating gas flow in the sorting chamber (2), the rotating gas flow having a rotation axis which corresponds to an upward axis (10) of the sorting chamber (2).
