In a state that has some of Australia\u2019s largest cement producers, Queensland.<\/p>\n<p>\u201cThe program with CQ University has delivered some very promising results that further highlight the superiority of the company\u2019s Toondoon kaolin and the potential to produce a high reactivity metakaolin product that could be used as a SCM to support production of low carbon cement and concrete,\u201d Burkhart says.<\/p>\n<p>\u201cThe use of HRM as an SCM unlocks a considerable commercial opportunity for the company and we will continue to advance discussions with industry and explore commercial pathways that could catalyse metakaolin production in Australia as an SCM for concrete and future zeolite manufacturing.\u201d<\/p>\n<p>\u00a0<\/p>\n<h2><strong>Method behind the metakaolin <\/strong><\/h2>\n<p>The testing program has evaluated the optimum method of pozzolanic activation of four raw ore kaolin samples from Queensland\u2019s Toondoon project, and two raw ore kaolin samples from ZEO\u2019s other kaolin project in Abercorn, to maximise their potential commercial value.<\/p>\n<p>ZEO reports that the results from the characterisation and reactivity tests have shown that all four kaolin samples from Toondoon are considered high-grade kaolin clays with high pozzolanic reactivity, capable of producing HRM.<\/p>\n\n<p>According to the compressive testing results ZEO\u2019s HRM can be produced from a range of profiles from the company\u2019s Toondoon raw ore kaolin, with \u201cminimal beneficiation, that meets the applicable standards for compression\u00a0 strength, and importantly, practical considerations\u00a0 such as workability.\u201d<\/p>\n<p>\u00a0<\/p>\n<h2><strong>ZEO: Rocking a hard place<\/strong><\/h2>\n<p>Zeotech expects to undertake a cost-benefit analysis of the potential economic benefits of its metakaolin products, together with life-cycle analysis that could evaluate the carbon benefit from using the metakaolin product in cement and concrete.<\/p>\n<p>Burkhart says his team has already begun work on a test pit at the Toondoon project.<\/p>\n<p>His plan is to be sitting atop a high-grade raw kaolin stockpile of about 50 tonnes and ZEO is ahead on plans to produce even larger quantities of metakaolin.<\/p>\n<p>\u201cWe want to further support cement industry pilot trials and broader collaboration initiatives. We want to bring some real solutions to market,\u201d Burkhart says.<\/p>\n<p>\u201cI\u2019d like to extend my thanks to project leaders, Dr Kumaran Suntharavadivel, and Dr Hassan Baji, from CQ University, for their effort and expertise that not only delivered some excellent results, but demonstrates the strong prospects of the company\u2019s kaolin across a variety of profiles.\u201d<\/p>\n<p>\u00a0<\/p>\n\n<p><span class=\"mce_SELRES_start\"><\/span>\u00a0<\/p>\n<p><em>This article was developed in collaboration with Zeotech, a Stockhead advertiser at the time of publishing.<\/em><\/p>\n<p><em>This article does not constitute financial product advice.\u00a0 <\/em><em>You should consider obtaining <\/em><em>independent advice before making any financial decisions.<\/em><\/p>\n<p>\u00a0<\/p>\n<p><span class=\"et_bloom_bottom_trigger\"><\/span><\/p>\n<p>The post <a href=\"https:\/\/stockhead.com.au\/tech\/zeotechs-latest-metakaolin-results-could-cement-its-spot-as-major-player-in-australias-transition-to-low-carbon-concrete\/\">Zeotech\u2019s latest metakaolin results could cement its spot as  major player in Australia\u2019s transition to low-carbon concrete<\/a> appeared first on <a href=\"https:\/\/stockhead.com.au\/\">Stockhead<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Special Report: Zeotech (ASX: ZEO) has released the latest data from its joint metakaolin testing program with CQUniversity, proving that HRM \u2013 or high reactivity <a href=\"https:\/\/economicherald.net\/?p=8645\" class=\"read-more-link\">[more&#8230;]<\/a><\/p>\n","protected":false},"author":0,"featured_media":8646,"comment_status":"","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[],"class_list":["post-8645","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-finance"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
