Abstract
Article made of conglomerate material in the form of a slab including an aggregate which includes granules of expanded material having a selected particle size range and defining between them inter-granular cavities containing only air and no filling material. The aggregate also includes a binder present in a controlled minimum quantity sufficient for lining the granules of expanded material. The article also includes a lining layer integral with the aggregate. Also, a method for the production of an article made of conglomerate material.
Claims9
A method for production of an article made of conglomerate material in the form of a slab and comprising an aggregate, the method comprising the following steps:
- preparation of an initial mix containing granules of expanded material and a binder, the granules of expanded material forming inter-granular cavities there between;
- deposition of said mix on a temporary support or in a mould;
- compaction of said mix;
- hardening of said binder and said mix so as to form the aggregate and obtain the article in slab form;
- wherein said binder is present in a minimum controlled volumetric quantity sufficient for lining the granules, the inter-granular cavities formed between said granules containing only air and being without filling material;
- and
- wherein the volumetric quantity of said binder is between 8% and 10% by volume of a total volume of the article;
- characterized in that the method comprises at least one step of applying a lining layer on at least one surface of said aggregate, said lining layer being integral with said aggregate after said at least one application step.
