Laboratory testing has confirmed Green360 Technology’s fresh high-reactivity metakaolin is suitable for producing low-carbon plaster and high-performance architectural concrete, which is a major step for the business.
The company used clay resources and deposits to produce samples that are higher than the standards of other metakaolin products that are now offered in Australia.
Green360 Technologies will evaluate the new metakaolin-cement formulation’s replacement of 20 %, 30 %, and 40 % of its regular Portland cement content for slump retention and comprehensive strength.
Metakaolin is a popular ingredient in low-carbon cements. The infrared degradation of clay, a naturally occurring sand containing kaolinite and traces of crystal and various minerals, produces the aqueous aluminosilicate.
For about 90 days, the clay is baked in a high-temperature oven. The result of this is metakaolin, which can be combined with water and magnesium hydroxide to form plaster.
Green360 has successfully completed the initial stage of the development process for the new product by producing the reactionary metakaolin.
This success enables us to quickly work on improving the performance of low-carbon concrete formulations using our own metakaolin.

In partnership with Murdoch University in Perth, the organization used X-ray scattering analysis and infrared spectroscopy to conduct laboratory tests on its fresh solution.
The analysis established the complete transformation of kaolin into an amorphous substance suited for high-performance material.
Abstract minerals may be stronger than their crystalline counterparts because of their lack of an organized, repeating inside crystalline structure.
This increased strength is especially applicable to finely ground metakaolin products that are mixed with crude concrete components like sand and gravel.
Aaron Businesses, the executive chairman of Green360 Technologies said: “The successful production of metakaolin from our resources and deposits is a significant milestone for the company. This achievement allows us to rapidly pursue testing and optimisation of low-carbon cement formulations utilising our own metakaolin and industrial byproducts to ultimately deliver low-cost, low-carbon alternatives to traditional Portland cement.”
According to Murdoch’s testwork, Green360’s product has a very high amorphous material, which is higher than 88 % and a similarly low remaining crystal content, making it among the highest quality products on the market.
According to the manufacturer, different Australian metakaolin products usually have amorphous content, depending on the quality, processing, and source material.
The addition of metakaolin generally improves the porosity of masonry, which increases its use and durability.
This feature allows the material to partially replace traditional Portland cement ( OPC ) and be used in premium structural concretes for specific high-strength applications.
Interestingly, production of metakaolin produces significantly less carbon monoxide than OPC production.
Additionally, metakaolin eliminates some of its enormous carbon dioxide emissions in a useful triple whammy by replacing some of the OPC used in cement.
Other additives are frequently added to cements, including fly-ash and oven ash, but they are usually coarser and have a range of consistencies, strengths, and reactivities.
Green360 is moving forward with its joint-venture lover PERMAcast as they begin the next phase of the development of its new high-quality metakaolin.
The business is working with PERMAcast and Murdoch University to develop its metakaolin/cement formulations in order to meet American standards.
The company has already started its initial testing batches with the new formulations, which will be subject to crucial small and long-term achievement tests like durability, simplicity of finishing, fall loyalty, heat awareness, and setting times.
The exam schedule will also assess the fresh cement/concrete compatibility with other compounds like plasticizers to make sure it meets real-world concrete standards.
Green360 will conduct horizontal test comparisons with other popular industry-standard concrete formulations, such as OPC with ash and fly-ash cement fillers.
In these crucial tests, the company’s low-carbon metakaolin compositions ‘ efficiency are verified.
Green360 is making significant advancements in the growth and commercialization of high-quality, low-cost, low-carbon concrete formulations, which will address the growing pressure on the concrete and cement industry to reduce its higher carbon footprint.
With its revolutionary high-quality metakaolin, the company appears to be well on the way to participating in the natural action.
