Yet, the quick-curing concrete only lasts for decades, while the other lasts for millennia. When the temple&#8217;s Indian architect specified strength and longevity, it was clear that modern concrete simply wouldn&#8217;t do, nor would &#8220;modern&#8221; builders attempt the experiment&#8230; which is where professor Kumar Mehta came in.<\/p>\n<p>Mehta knows concrete. Returning to the mixture of cement and fly ash used by ancient Greeks and Romans, Mehta fashioned a foundation in which 60% of the portland cement is replaced with fly ash. To create the two 6,500sf pads for the stone temple, Mehta&#8217;s team used only 80 tons of cement, instead of the 230 tons of cement and 75 tons of steel required with conventional reinforced concrete.<\/p>\n<p>With cement production now contributing more than 6% of global greenhouse gases and growing fast, alternative construction methods are mandatory. By mixing in some fly ash, we could reduce cement use by half.<\/p>\n<p>Prof Mehta says, &#8220;This demonstrates a revolutionary method of concrete construction which, if widely adopted could save millions of dollars a year, create structures to last far longer than they do now and substantially reduce the introduction of carbon dioxide to the atmosphere.&#8221;<\/p>\n<hr \/>\n","protected":false},"excerpt":{"rendered":"<p>geongrid.geo.arizona.edu KAUAI, HAWAII, November 16, 2007: Kauai&#8217;s Hindu temple got a foundation built to last 1,000 years, and it just,&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-6490","post","type-post","status-publish","format-standard","hentry","category-news"],"_links":{"self":[{"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/posts\/6490","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/comments?post=6490"}],"version-history":[{"count":0,"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/posts\/6490\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/media?parent=6490"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/categories?post=6490"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/tags?post=6490"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
