Abstract

A design of experiments methodology was carried out for the development of a construction ceramic material using electric arc furnace slag (EAFS) and other metallurgical wastes such as aluminum dross (AD) and green moulding sand (GMS). The factors evaluated were %wt. of bentonite, ratio EAFS/AD, fineness index of raw materials (AFS number), sintering temperature and sintering time. The specimens were sintered and subsequently their compressive strength was evaluated. It was determined that sintering temperature, AFS number and EAFS/AD ratio had the greatest impact on the compressive strength. The best conditions to achieve strengths for use of this material as brick, (10.3 MPa), were high temperatures of sintering, fine particle size, high ratio EAFS/AD, low contents of bentonite and short sintering times. Following these conditions, compressive strengths >21 MPa were achieved. Therefore, it is feasible the use of EAFS-AD mixture as a partial substitute for the elaboration of structural bricks with a superior compressive strength.
