Abstract Scope |
Reintroducing the generated waste to another production process is a sustainable alternative that reduces the ecological environmental impacts caused for them and enables the production of materials with good properties. The objective of this work was to produce an artificial stone from granite waste and the steel residue Flue Gas Dessulfurization (FGD) agglutinated by polyurethane from castor oil to be used as coating in construction. The particles were crushed and sieved into three granulometric ranges: coarse, medium and fine. Afterwards, the granulometric composition of larger packages for the production of stone was determined. Artificial stones in the dimensions of 100 x 10 x 10 mm were produced in a metalic mold using vibration, vaccum and campression. The results obtained proved the good mechanical performance of the stone within the expected ranges, low water absorption and apparent porosity, demonstrating its capacity. |
