Abstract: A method for cutting a slab of material including cutting the slab with a cutting tool vibrating at a preselected frequency when the material is in a semi-set state.

Abstract: A method for producing a laminated product including applying a slab product to at least one surface of a substrate, the method including placing the substrate onto the slab material when the slab product is in a semi set partially cured state, then allowing the laminated product to cure. Preferably the slab is cement based and the substrate is a masonry product, already manufactured and cured, e.g., tiles, mosaics, bench tops. The method may alternatively cast a cementitious slab first, and then when that is partially cured pour the cementitious substrate onto it, then cutting the whole assembly into smaller pieces while the whole assembly is still in a partially cured semi set state.

Abstract: The present invention provides a method of processing cementitious products to substantially reduce or eliminate efflorescence. The method includes applying a protective layer to at least one surface of a slab product at the time of pouring cementitious mix into a mould and retaining the protective layer in place. The protective layer is a relatively thin sheet of plastic material.

Abstract: A method for producing a cementitious slab including mixing together cement with other materials with the combined mixture of materials having physical particle sizes sufficiently small to allow the material to be cut with a vibrating cutting tool when the material is a semi-set state.
