Development of Epoxy Matrix Artificial Stone Incorporated with Sintering Residue from Steelmaking Industry

Abstract

The present work is part of an innovation research project aiming to develop artificial stone from industrial wastes. In principle, the project goal is to fabricate artificial stones with improved characteristics to be used as plates for housing and road construction. In this work, the specific industrial residue was an electrostatically precipitated powder obtained from the initial sintering stage of an integrated steelmaking plant. Plates were produce by vacuum vibro-compression of epoxy resin mixed with 80 and 85 wt% of this specific residue. After curing, the plates were characterized for physical parameters and mechanical properties. The microstructural aspect of the finishing surface was analyzed for both novel artificial stones by scanning electron microscopy. The results indicated that the 80% residue incorporated artificial stone is superior to the 85% residue incorporated and markedly stronger than a commercial artificial stone, incorporated with granite residue, with comparable density and water absorption. These characteristics favor the technical substitution of the presently investigated artificial for the commercial stone. In particular, based on wear tests, the residue incorporated artificial stone would be restricted to application as pavement in medium traffic roads.

Stability of Nanocomposite Edible Films Based on Polysaccharides and Vitamin C from Agroindustrial Residue

“…The good use of agroindustrial residue has motivated many studies and applications. From the environmental point of view, the correct destination of these residues is desired in order to minimize the environmental impact and accumulation of waste 1 . On the other hand, from the technological point of view, these residues can be driven for extraction of molecules and macromolecules with bioactive properties, having potential for economic exploitation.…”

Recycling of waste artificial marble powder in HDPE‐wood composites

“…More than 217 million m 2 of artificial marble has been produced in China in 2013 and the yield goes up with a rate of 20% to 30% each year. The manufacture and process of these marble primarily contains three steps, namely sawing, polishing, and finishing . Millions tons of crushed artificial marble wastes from artificial marble processing are generated every year and these wastes can be sorted into different forms, like bulk, granule, fine powder, slabs, damaged blocks, and so on .…”

Description and effective parameters determination of the production process of fine-grained artificial stone from waste silica

“…High water absorption of 0.25% and 0.38% reported by Borselino et al and Carvalho et al, respectively. One of the reason is that the porosity of this method is lower than other methods [34,35]. A possible explanation is that this artificial stone can be sealed with low water absorption.…”
