Claim 0:
1. A method for producing a solid construction material, the method comprising:
extracting a mineral fraction comprising argillaceous particles from a soil;
preparing a first aqueous grout from at least one part of the extracted mineral fraction;
adding a dispersing agent to the first aqueous grout to disperse the argillaceous particles there to obtain a second aqueous grout,
adding a coagulating agent to the second aqueous grout to agglomerate the argillaceous particles therein to obtain an aqueous construction material grout;
introducing the aqueous construction material grout into a formwork; and
allowing the evaporation of the water contained in the aqueous construction material grout to obtain the solid construction material,
wherein the solid construction material is a supporting element having a compressive strength of at least 1.4 MPa.
