“…In general, WFS contains less silica compared to quartz sand due to the additives present in WFS [10]. Table 5 gives the different reported chemical compositions of WFS [3,9,10,33,34] in comparison with the WFS in my study. The chemical composition of WFS may vary depending on the type of metal, combustible used, as well as the type of binder.…”

Waste foundry sand (WFS) is a ferrous and non-ferrous foundry industry by-product, produced in the amount of approximately 700 thousand tons annually in Poland and it is estimated that only a small percentage of this waste is recycled. The study used WFS to produce ultra-high performance concrete (UHPC) as a partial substitute for quartz sand. It was replaced with WFS levels of 0%, 5%, 10%, and 15% by weight of quartz sand content. The UHPC mixtures were produced and tested to determine the compressive strength, flexural strength, splitting tensile strength as well as the modulus of elasticity at 28, 56, and 112 days. Scanning electron microscope (SEM) analysis was done to identify the presence of various compounds and micro-cracks in UHPC with WFS. The results revealed an increase as well as an insignificant decrease in the mechanical properties up to 5% and 10% WFS replacement, respectively. These studies also prove improvement in the microstructure of UHPC up to a 5% WFS level. In all the tested properties in this work, 5% WFS was found to be an apt substitute for quartz sand.

“…Entre as alternativas de reaproveitamento dos resíduos deste estudo, alguns trabalhos comprovaram a viabilidade de inserção em obras de infraestrutura, como no uso com materiais para aterramento, reforço para construção de estradas e produção de misturas asfálticas (CARNIN, 2008;JAVED, 1992;YA-ZOGHLI-MARZOUK et al, 2014); em concreto estrutural, concreto para blocos de pavimentos e tijolos (BHARDWAJ; KUMAR, 2017; KHATIB; HERKI; KENAI, 2013;LADOMERSKÝ et al, 2016;RESCHKE, 2003) e no desenvolvimento de barreiras ou revestimentos hidráulicos (ABICHOU; EDIL; BENSON, 2004). Para a utilização dos resíduos de fundição nessas aplicações é necessário que eles apresentem, principalmente, granulometria semelhante aos agregados naturais e elementos químicos em sua composição, como sílica e alumina, que contribuam para a melhoria das propriedades mecânicas e a redução da permeabilidade dos materiais em que são incorporados como matérias-primas.…”

A geração e a disposição de resíduos oriundos da fundição de metais despertam a necessidade de alternativas que promovam seu melhor reaproveitamento em processos produtivos. Assim, este estudo realizou a caracterização química, mineralógica e granulométrica de resíduos de fundição de ferro cinzento e nodular e avaliou sua aplicabilidade na construção civil. A areia verde, escória e material particulado apresentaram em sua composição química a presença majoritária de dióxido de silício (SiO 2), além de óxido de alumínio (Al 2 O 3), óxido de potássio (K 2 O) e óxido de ferro (Fe 2 O 3). A análise mineralógica revelou a presença de quartzo em todos os resíduos e de hematita, na escória. Os três resíduos apresentaram granulometrias compreendidas entre 0,002 e 0,6 mm. Identificou-se que os resíduos possuem potencialidade de uso na produção de cimento, argamassas e materiais cerâmicos, como substituintes parciais dos agregados miúdos do concreto e como material da camada de sub-base de pavimentos. Palavras-chave: produção de peças fundidas; subprodutos; composição química e mineralógica; reaproveitamento; cerâmica e concreto.

This state of art review represents the development in the field of utilization of used foundry sand in cementitious concrete. The paper reviews the utilization of foundry sand as the concrete constituent and the noticeable and important findings from the experimental works of various researchers. The historical development is also discussed as a part of introduction in the review. After a careful study of large number of research papers on the topic it was felt by the authors to integrate all the important results for streamlining the potential of this area of research. The paper summarizes conclusions of experiments conducted for the properties like strength and durability. It was observed the results have shown positive changes and improvement in strength and durability properties of the conventional cementitious concrete due to the addition or replacement of fine sand with used foundry sand in different proportions. However in couple of cases such addition has reported reduction in the values of properties. From the review of past research works it could be concluded that utilizing the used foundry sand holds a great potential towards the development of environment friendly and sustainable cementitious concretes.
