A team from RMIT University, Australia, combined the durability of rammed earth\u2014a construction technique used to make walls from compressed soil within a lattice of sticks or bamboo\u2014with the versatility of cardboard, creating a reusable material made from cardboard, water, and soil. According to the researchers, the new material, called cardboard-confined rammed earth, eliminates the need for cement, has one-quarter of the carbon footprint of concrete, and comes at less than one-third of the cost. \u201cBy simply using cardboard, soil, and water, we can make walls robust enough to support low-rise buildings,\u201d said RMIT\u2019s Jiaming Ma in a university statement. A cardboard-confined rammed earth wall could be produced on-site by compacting the soil and water mixture inside the cardboard formwork, either manually or with machines. According to Ma, this could be an effective solution for construction in remote areas where red soils\u2014ideal for rammed earth construction, a technique still widely used around the world\u2014are plentiful. The mechanical strength of the novel building material varies according to the thickness of the cardboard tubes (Structures<\/em><\/a>, October).<\/p>\n","protected":false},"excerpt":{"rendered":"Scientists create building material from cardboard, soil, and water","protected":false},"author":475,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[2413],"coauthors":[785],"class_list":["post-576802","post","type-post","status-publish","format-standard","hentry","category-notes","tag-technology"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/576802","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=576802"}],"version-history":[{"count":2,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/576802\/revisions"}],"predecessor-version":[{"id":576808,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/576802\/revisions\/576808"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=576802"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=576802"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=576802"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=576802"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
