METHOD OF FORMATION FOR COMPOSITE MATERIALS COMPRISING CEMENT AND GEOPOLYMER CONTAINING LAYERS, AND PRODUCTS OBTAINED FROM SUCH METHODS

摘要

The present invention relates to methods for forming a layered composite material, the finished product comprising at least one geopolymeric layer and at least one cement-based layer. The method of the invention allows the provision of products with more varied appearances, shapes, colours, gloss, or surface structures such as decorations, reliefs, roughness, or the like. Products obtained according to the method of the invention also form part of the invention.

主权项

1. A method for forming a layered composite material, comprising the steps of
(a) casting a first castable composition into a mould to obtain a first cast composition; (b) applying a binder composition to at least one external surface of the said first cast composition obtained at the end of step (a); and (c) at the end of step (b), casting a second castable composition onto the said at least one external surface of the obtained first cast composition in the said mould; characterised in that the said first castable composition is one selected from a group consisting of a geopolymer containing or geopolymer forming composition and a calcium silicate-based cement containing composition and the said second castable composition is the other one of the same group consisting of a geopolymer containing or geopolymer forming composition and a calcium silicate-based cement containing composition.
