Abstract:
1. A reinforced building element including: a rigid cementitious substrate having a first face, wherein said cementitious substrate has a density range from 0.8 g/cc to 1.5 g/cc; a layer of ultraviolet (UV) radiation curable resin, said UV radiation curable resin is formed on the first face of the rigid cementitious substrate, said UV radiation curable resin comprising about 10 to 50% by weight of lower molecular weight monomers and about 10 to 50% by weight higher molecular weight oligomers; and a layer of reinforcing material having an upper surface, wherein said reinforcing material is adhered to said first face of said rigid substrate by the UV radiation curable resin which is disposed between the reinforcing material and the first face of the rigid substrate, wherein the reinforcing material is partially embedded in the layer of UV radiation curable resin in a manner such that the upper surface of the reinforcing material stands proud of the radiation curable resin, said reinforcing material having substantially the same or higher modulus of elasticity to that of the cementitious substrate such that UV radiation curing can pass sufficiently through or around the reinforcing material to cure the resin embedded therein sufficiently to adhere the reinforcing material to the cementitious substrate.
