Diseño de mezcla de suelo-cemento con incorporación de relaves de minas de oro como propuesta de un nuevo material para la construcción

Abstract

Abstract: This study explores the production of geopolymeric bricks from mine tailings gold from the PITUCA ll concession. It simultaneously addresses two industrial challenges: mining waste management and the need for sustainable construction materials. Through geopolymerization, the feasibility of using these tailings, rich in aluminosilicates, to manufacture soil-cement bricks. It was experimented with variables such as the molar concentration of the alkaline activator (10M and 12.5M), the percentage of solution alkaline (24% and 26%), and molding pressure (1500lb, 2000lb). The results indicate that the most efficient combination is 12.5M molar concentration of the activator, 26% of alkaline solution content and 90°C temperature, reaching a resistance to compression of 12.38 Mpa and a flexural strength of 1.35 Mpa. It is also concluded that higher molar concentrations of the alkaline activator improve resistance to brick compression. This approach is not only promising for the production of greener building materials, but also offers a practical solution to mining waste problem.
