Abstract

SANTACRUZ-TORRES, Jessica  and  TORRES-AGREDO, Janneth. Using Secondary Lead Smelter Slag in Ceramic Bricks. Cienc. Ing. Neogranad. [online]. 2019, vol.29, n.1, pp.7-18. ISSN 0124-8170.  https://doi.org/10.18359/rcin.3495.

Secondary lead slag is a waste product obtained from the smelting of used lead battery, and it becomes a major air, soil, and water pollutant when not properly stabilized. Thus, this study assesses the technical feasibility of aggregating this waste to produce ceramic bricks and to test the immobilization of several heavy metals contained in the slag used for prepared products. The results revealed the feasibility of substituting 15% of the clay with slag, thereby reporting an improvement in the compressive strength of bricks in which this waste was aggregated, unlike regular bricks. Additionally, the study determined the immobilization of lead, arsenic, and selenium in these final products.
