“…Literature still reports not much works about the reuse of UFS as aggregate for cement -based materials and with discordant results. When UFS is used as a partial sand replacement, some papers report an increase [1,16,19], others a decrease [15,17,18,22], in compressive strength, probably because the casting process and the industry sector from which UFS originates has a strong influence on their physical and chemical characteristics.…”

“…Indeed UFS has been extensively investigated both as a constituent material for controlled low-strength materials [13], for mortar and concrete [14][15][16][17][18][19][20][21][22][23] and self compacting concrete [24][25][26]. However, currently, the percentage of these materials used in cementitious materials is not at the desired sustainable level.…”

Resumom dos resíduos gerados pela indústria de fundição que tem potencial de aplicação na construção civil é a areia de fundição. O objetivo deste trabalho foi caracterizar e verificar a influência do teor do resíduo de areia de fundição fenólica em argamassas de revestimentos trabalháveis. Foram confeccionadas argamassas mistas, substituindo a areia natural, em volume, nos teores de 0%, 10%, 30% e 100% pelo resíduo de areia de fundição. Para os resíduos de areia de fundição e das argamassas foram realizados ensaios de corrosividade, reatividade, lixiviação e solubilização. Com os dados obtidos foi possível verificar a influência do resíduo de areia de fundição nas propriedades do estado fresco (principalmente na argamassa com 100% do resíduo de areia de fundição, que demandou uma quantidade de água maior para a mesma consistência) e do endurecido (redução nas resistências, na densidade de massa e no módulo de elasticidade). Notou-se que as argamassas com resíduos de areia de fundição, em comparação com o resíduo de areia de fundição, apresentaram menor concentração de ferro, fluoreto e sódio, e maior de alumínio, cromo total e fenóis totais. Os resíduos estudados foram classificados como não perigosos -Classe II A -não inertes, segundo a NBR 10004 (ABNT, 2004

“…Over the last decade or longer, a number of countries (e.g., Brazil, USA, India, Argentina) have been investigating the beneficial use of WFSs (Jing and Barnes 1993;Sota et al 2007;Carnin et al 2010;Singh and Siddique 2012). Diverting WFSs from landfills makes practical economic and environmental sense, since foundries can save on disposal costs, while end users decreased demand for virgin aggregate alleviates the environmental burdens associated with mining activities.…”

While most waste foundry sands (WFSs) are not hazardous, regulatory agencies are often reluctant to permit their beneficial use in agricultural and geotechnical applications due to concerns over metal leaching. The objective of this study was to quantify total and Toxicity Characteristic Leaching Procedure (TCLP) metals in 16 waste sands from Brazilian ferrous foundries then assess their potential to leach to groundwater using a probabilistic model. Total and TCLP metal concentrations in the non-hazardous sands fell within ranges as reported in the literature, although some of the leachate concentrations were found to exceed drinking water and groundwater maximum contaminant levels (MCLs). Leachate values above the MCLs were then used in the model to estimate groundwater concentrations at hypothetical wells up to 400m downgradient from a land application unit. A conservative scenario of 1 ha of land applied WFS, and high annual rainfall totals (low evaporation) suggested that groundwater concentrations of Ba, Hg, Mn, Ni, and Pb could potentially exceed health-based MCLs at most wells. While a wet climate can exacerbate the transport of metals, land application of WFSs in areas with moderate rainfall totals or high rainfall, high evaporation was predicted to be protective of groundwater quality and human health.
