APPLICATION OF RESINOUS BINDERS WITH INCORPORATION OF CARBONATED SLUDGES FROM THE DIMENSION STONE INDUSTRY IN THE PRODUCTION OF STONE COMPOSITES

Abstract

The carbonated dimension stone extrac8ve and processing industry produce high amounts of wastes that are deposited in the open in heaps and deposits of carbonated sludge (Fig. 1). The industrial applica8on of this waste makes it possible to add value, transforming it into a byproduct, thus contribu8ng to the framing of the limestone and marble extrac8ve and processing sub-sectors, in the “Ac8on Plan for the Circular Economy”, promo8ng the sustainable growth. By this means, this research has shown that the recycling slurries as a raw material are possible to integrate binders produc8on through its incorpora8on on the manufacture of ornamental stone composite materials, par8al or totally replacing the epoxy resins tradi8onally used in this type of products.
