NTU said up to 100Mt of waste foundry sand, a by-product the metal casting industry, could be averted from landfill and used to make the new material.<\/p>\n<p>Concrete is typically composed of sand, cement, aggregate and water, while foundries purchase siliceous sands to create moulds that give shape to melted metals for casting. These sands become waste after several uses and must be properly recovered or disposed of. Any improper disposal of waste foundry sand can cause environmental issues. The NTU research, led by Professor Amin Al-Habaibeh, showed that concrete made with waste foundry sand has a compression strength of around 23N\/mm2. With a substitution ratio of up to 30%, recycled waste foundry sand-based concrete&#8217;s compression strength was the equivalent of up to 78% of normal concrete.<\/p>\n<p>He said that worldwide it has been estimated that annually the foundry industry generates approximately 100Mt of waste foundry sands, where the majority of that sand will end up discarded in landfills.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.newcivilengineer.com\/latest\/research-project-repurposes-waste-sand-from-foundries-to-make-concrete-for-lighter-loads-24-10-2023\/\">New Civil Engineer<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/5-425\/\">Research project repurposes waste sand from foundries to make concrete for lighter loads<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[3802,575,11978],"class_list":["post-117917","post","type-post","status-publish","format-standard","hentry","category-news","tag-concrete","tag-environmental-news-en","tag-waste-sand"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/117917","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/comments?post=117917"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/117917\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=117917"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=117917"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=117917"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
