<p>A prefabricated composite structural layer is provided that is suitable for inclusion in a prefabricated structural wall panel assembly or façade for a building wherein the structural layer has an ultra-high performance concrete (UHPC) layer permanently bonded to at least a first layer of high performance concrete (HPC) to form a laminated construction including the UHPC layer and first layer of HPC permanently bonded thereto. The UHPC layer is preferably bonded to the first HPC layer by moulding uncured HPC directly in contact with uncured UHPC so that cement in the two layers forms a continuous cementitious matrix and the two layers are bonded together by the resultant cured cement. Also provided are prefabricated building panel assemblies in which at least one of such prefabricated composite structural layers forms the outside of the building panel and another panel that may be the same or similar with thermal insulation between them.</p> |
