Abstract: A composition for producing an item for street furniture comprises: finely subdivided inert materials, an alkali metal polysilicate, a structuring agent, a surface-active agent; a method for producing an item for street furniture comprises: dispersing finely subdivided inert materials in a solution of an alkali metal polysilicate, so as to obtain a mixture; adding a surface-active agent and a structuring agent to said mixture; pouring said mixture into mould means and enabling said mixture to solidify, so as to produce said item.

Abstract: A composition for producing a building item comprises: finely subdivided inert materials, an alkali metal polysilicate, an oxidizing agent, formaldehyde; a method for producing a building item comprises: dispersing finely subdivided inert materials in a solution of an alkali metal polysilicate, so as to obtain a mixture; adding an oxidizing agent and formaldehyde to said mixture; pouring said mixture into a mould, so as to enable said mixture to expand in volume, solidify and produce said item; drying said item.

Abstract: A composition for manufacturing a product, comprises: finely subdivided inert materials, a metal oxide, a metal chloride, a resin, a thickening agent, a surfactant; a method for manufacturing a product comprises: mixing a solution of metal chloride with a metal oxide and finely subdivided inert materials, so as to obtain a mixture; adding to said mixture a resin, an a surfactant; pouring said mixture into a mould in such a way as to impregnate a fibre material sheet positioned inside said mould; enabling said mixture to solidify, so as to manufacture said product.
