Abstract
A process for manufacturing slabs of stone material such as marble or granite, reinforced with reinforcing elements in particular made of steel and fixed to a rear surface of the slabs by a bonding resin of the hardening type. The resin is used to impregnate non-twisted strands of glass, preferably in the form of matting, in a percentage weight ratio of glass strands to resin of at least 50:50, with a preference for a quantity by weight of glass strands greater than 50%.
Claims20
A process for producing reinforced slabs of products made of stone material, having a reinforcement which includes a hardened resin combined with a rear face of the slab, comprising
- providing a slab of stone material having a rear substantially smooth face free of grooves or recess;
- providing non-twisted linear reinforcing elements;
- coating the non-twisted linear reinforcing elements with a coating of a resin to form a reinforcement having a percentage ratio by weight of resin to the non-twisted linear reinforcing elements of at most 50:50;
- inserting a reinforcing layer between the coated non-twisted linear reinforcing elements and the rear face of the slab of stone material;
- and
- hardening of the resin.
