ABSTRACT:
A method for making a regenerated soil material for the production of a structural unit includes the steps of: a) obtaining a raw soil material containing aluminum and silicon from a natural source; b) adding an active mineral containing aluminum and silicon to the raw soil material; c) cleaving the raw soil material and the active mineral in a base so as to dissociate aluminum monomer and silicon monomer out of the mixture of the raw soil material and the active mineral; and d) polymerizing the aluminum monomer and the silicon monomer so as to form silicon-oxy tetrahedron and aluminum-oxy tetrahedron in the mixture.
