Estimating the term…
The invention relates to a process for manufacturing a reconstituted mineral aggregate, characterised in that at least one particulate mineral starting material is mixed with water and at least one mineral binder which can be hardened in the presence of water and/or at least one system capable of forming a hardened mineral binder in an aqueous medium, to obtain a material in the form of a wet powder which is compressed by extrusion or pressing in order to intimately mix the binder and/or system capable of forming the binder/particulate starting material/water and to increase the intrinsic density and reduce the intrinsic porosity of the material, and to obtain, as a result of the hardening the binder or binders, a hardened, solid mass which is in the form of the granulate of the size and/or shape desired, or is transformed into the granulate of the size and/or shape desired by cutting or crushing, immediately after compression or in a subsequent stage.

Process for manufacturing a reconstituted mineral aggregate, wherein at least one particulate mineral starting material for aggregate is mixed with water and at least one mineral binder which can be hardened in the presence of water and/or at least one system capable of forming a hardened mineral binder in an aqueous medium, in order to obtain a material in the form of a wet powder which is compressed by extrusion or pressing in order to intimately mix the binder and/or system capable of forming the binder/particulate starting material/water and to increase the intrinsic density and reduce the intrinsic porosity of the material, and to obtain, as a result of the hardening of the binder or binders, a hardened, solid mass which is in the form of the granulate of the size and/or shape desired, or is transformed into the granulate of the size and/or shape desired by cutting or crushing, immediately after compression or in a subsequent stage.
