A Study on Foundry Sand: Opportunities for Sustainable and Economical Concrete

Green concrete is concrete produced using waste materials obtained from various sources to develop an eco-friendly construction and reduce carbon emissions. The present experimental study is carried out to produce concrete using waste material from different industries to partially replace traditional concrete. Many research studies have been made using different waste materials which are available and useful as a replacement. The present study deals with industrial waste such as foundry sand (FS) and ground granulated blast furnace slag (GGBS) in the concrete so that the emission can be reduced and contribute to the environment. This study prepared two mixes for M35 Grade by replacing industrial wastes partially in the concrete mix. The first mix was prepared by partially replacing foundry sand with fine aggregates in proportions of 15%, 20%, 25% and 30%. The second mix was prepared by partially replacing the ground granulated blast furnace slag with cement in proportions of 30%, 40% and 50%. Test results were conducted to check the workability and compressive strength of the mixes prepared. These were then compared with the properties of conventional concrete at the end of 7 and 28 days. Test results indicate that 25% of FS and 30% of GGBS are the optimum percentages of industrial waste to use compared to conventional concrete properties at the end of 7 and 28 days. The present study also indicates the economic benefits of partially replacing the waste materials by reducing carbon emissions, and the study is beneficial to produce eco-friendly green concrete.

“…The results showed that the workability of 30 % replacement of fine aggregate was adequate and the strength performance was better than all proportion. Bhimani also [11] analyzed the strength (compressive, split tensile strength and flexural strength) of concrete while utilizing the foundry sand as fine aggregate replacement. The different proportions 0, 15, 25 and 35% were adopted.…”

In Pakistan construction Industry, concrete construction is cheaper than the other construction methods with respect to that construction materials demand rises. The 75% volume of total concrete fill with aggregate which contributes to decrease the natural aggregate resources day by day. The best solution for this problem is to utilize River Indus sand and recyclable concrete aggregate as fine and coarse aggregate respectively. In this research the River Indus sand and recyclable coarse aggregate were fully replaced with normal aggregates. The aim of this study was to examine the flexural and tensile performance of concrete containing the River Indus sand and recyclable concrete aggregate. The physical properties were also examined which include the sieve analysis and chemical composition of River Indus sand. The M15, M20 and M25 grade were analyzed at 7, 14, 21 and 28 days water curing. The results define that, flexural strength was reduced from 5% to 15% compared to normal aggregate whereas tensile was decreased from 1% to 1.8% at 28 days water curing.

“…O crescimento humano e industrial tem provocado uma diversidade de impactos ambientais, tais como o aumento de demanda de energia com o consequente esgotamento de recursos não renováveis e uma grande geração de resíduos sem destinação adequada que causam empobrecimento do solo, poluição ambiental e consequentes mudanças climáticas. Dois resíduos gerados em grandes volumes em nível mundial são os resíduos sólidos urbanos (RSU), com cerca de 2.01 bilhões de t/ano (Kaza et al, 2018) e o resíduo industrial areia descartada de fundição (ADF) com uma produção aproximada de 6 a 10 milhões de t/ano (Bhimani et al, 2013). A fundição compreende todo processo de fusão e vazamento de metal líquido em caixas de moldagem, com machos montados em seu interior, que caracterizará a peça após a solidificação do metal.…”

Este estudo apresenta os resultados da adição de diferentes taxas de resíduos de areia verde de fundição (RAVF) e substrato comercial a um composto, obtido da compostagem do resíduo sólido orgânico (RSO) segregado do resíduo sólido urbano (RSU). O RAVF, por apresentar textura arenosa, devido à sílica (SiO2), quando utilizado diretamente no solo, torna-o mais permeável causando o seu empobrecimento devido a uma maior lixiviação de nutrientes. O RSO, quando disposto diretamente no solo, gera chorume, biogás e contaminação da água. Atualmente, no Brasil, a maior parte do RSO é enviada para aterros sanitários e RAVF para aterros industriais não perigosos. No entanto, o alto custo, a escassez de áreas e a legislação cada vez mais exigente para a disposição destes resíduos, têm levado as indústrias e os municípios a buscarem alternativas para reuso do RAVF e tratamento do RSO. A metodologia deste trabalho inicia-se com a obtenção de um composto produzido de um sistema de compostagem com monitoramento automatizado de temperatura, taxa de aeração e umidade. Após a obtenção deste produto, ele foi misturado com diferentes taxas de RAVF e substrato comercial e posteriormente foi avaliada a fertilidade destes materiais. Para verificar a utilização destas misturas na agricultura foram avaliados os nutrientes do tecido vegetal da Avena Strigosa Schreb (aveia preta) cultivada nestes meios. Os resultados indicam que há o potencial para utilização destas misturas enquanto substrato vegetal na taxa de 10-20% de RAVF ou como corretivo para a acidez de solos na taxa de 10-30% de RAVF.
