A team led by chemist Andrea Cavicchioli, a professor at the University of S\u00e3o Paulo (USP), along with researchers from the Catadupa Farm Socio-Environmental Institute and Argentina\u2019s Regional Center for Research on Crude Earth Architecture, tested several combinations based on raw materials easily found in what is known as the S\u00e3o Paulo Historic Valley. This was the first region occupied by coffee plantations in the state of S\u00e3o Paulo, in the early 19<sup>th<\/sup> century. The oldest buildings there are in a precarious state of conservation. The formulation that performed best in the adherence and erosion\/water resistance tests conducted at Catadupa Farm in S\u00e3o Jos\u00e9 do Barreiro has several ingredients: termite mound earth and double-fine sand (sifted and mixed with fibers of a grass common to the region), in addition to a watery extract from cacti of the genus <em>Opuntia<\/em>. The study\u2019s findings were presented at a conference on earth-based architecture and buildings, held in Asunci\u00f3n, Paraguay, in October 2016.<\/p>\n","protected":false},"excerpt":{"rendered":"Termite mound earth is the ingredient in a new formulation of mortar","protected":false},"author":475,"featured_media":0,"comment_status":"open","ping_status":"open","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":[168],"tags":[212,243],"coauthors":[785],"class_list":["post-239282","post","type-post","status-publish","format-standard","hentry","category-technoscience","tag-biotechnology","tag-innovation"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/239282","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=239282"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/239282\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=239282"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=239282"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=239282"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=239282"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
