Green360 Technologies Ltd. has completed a practical plant trial of its Eco-Clay as an additive for sprayed concrete applications, achieving a 50 per cent reduction in Portland cement.
The trial, conducted at an Eifers plant in Victoria in collaboration with Complete Shotcrete, used standard batching and spraying equipment to construct a demonstration wall. The results confirmed that the low-carbon clay additive could be integrated into established concrete processes without compromising workability or performance.
Shotcrete, or sprayed concrete, is a staple of the Australian construction and mining industries, used extensively for tunnel linings, underground mines, and complex vertical structures.
Validating Eco-Clay in this high-demand sector opens a major new market for Green360, which operates the Pittong plant with a 60,000-tonne annual capacity.
Green360 Executive Chairman Aaron Banks hailed the trial as a major new market opportunity.
“The plant trial demonstrates our ability to integrate Eco-Clay into established concrete processes and is further evidence of Green360 establishing new market channels.
“Shotcrete demand could provide another pathway to lift utilisation of our Pittong plant’s 60,000 tpa capacity and accelerate commercial scale-up.”
The environmental benefits of the product are also significant. While traditional Portland cement requires heating up to 1,450 degrees Celsius, Eco-Clay is produced by heating kaolin by-products to just 750 degrees Celsius.
This lower energy intensity, combined with the 50 per cent cement replacement achieved in the trial, offers a significant reduction in the carbon footprint of civil infrastructure projects.
Eifers Managing Director Daniel Eifermann highlighted the practical necessity of the technology, noting that traditional additives like fly ash and slag are becoming increasingly scarce.
“Our work to date has demonstrated good workability and faster set times,” Eifermann said, confirming that Eifers is now committing resources to provide the product to its customers.
With the plant trial complete, Green360 intends to move toward larger-scale field trials and formal commercial supply agreements.
