Experts and engineers from Boral, Southern Highland Concrete Construction and UTS are taking part in a new two-year manufacturing research project. The project aims to overcome the current technological barriers of low-carbon concrete manufacturing and accelerate the development of Boral’s lower carbon ENVISIA® concrete

Following the award of $21m in grant funding from the Federal Government, SmartCrete CRC Ltd has been Incorporated and is on track to be operational in September this year!
Fly ash, inevitably generated by coal-fired power stations, has more worth than flooding landfills and ash dams worldwide.
It's ability to transform from a waste product into a environmentally friendly and economically savvy material is evident in geopolymer concrete. However, geopolymer structures exposed to highly alkaline conditions have shown low resistance, an undesirable outcome that researchers at the University of Johannesburg are tackling.
Opportunities arise for the concrete industry as it shifts towards sustainability with today’s technological advancements.
The International Energy Agency Clean Coal Centre has published a new report that expands on the growing market of coal fly ash. Beneficial Uses of Coal Fly Ash by Dr Ian Reid, Anne M Carpenter and Dr Alice Masili addresses the global shift in Coal Fly Ash (CFA) production and its increase in market value and importation demand for use across many sectors.
In the first trial of its kind, we’ve taken industrial waste from coal-fired power stations and steel manufacturing to create a new roadway. Working with researchers from the University of NSW, we’ve replaced a section of roadway on Wyndham Street in Alexandria to test the green concrete’s durability. Made from fly ash and blast furnace slag, geopolymer concrete is a sustainable blend of concrete and recycled materials.
Please note that the following draft’s public comment period is due to close in three days.
In a world-first project, researchers and NSW Ports have incorporated waste from coal-fired power stations into low carbon Geopolymer concrete.
Eight million tonnes of CO2 are produced in Australia each year, as well as 14 million tonnes of fly ash and three million tonnes of slag. By substituting Portland cement with slag and fly ash to make Geoploymer Concrete (GPC), significant CO2 reduction and economic benefit can be achieved
Energy Australia has signed a memorandum of understanding (MoU) to supply fly ash from its coal-fired power plant in Yallourn to a proposed magnesium production plant in the Latrobe Valley.
At the World of Coal Ash 2017 Conference in the United States, CEO Craig Heidrich presented the following report to a plenary of +1,100. View the World Wide Coal Combustion Products Network PDF now.
The new-generation, high-efficiency coal plants produce half the carbon dioxide emissions of existing ones, making them comparable with gas and the Minerals Council says it is “simply common sense” that new coal technologies be considered as part of Australia’s efforts to meet its emissions reduction targets.
The Coal Combustion & Gasification Products Journal is a collaboration between the American Coal Ash Association and the University of Kentucky Center for Applied Energy Research, with the Ash Development Association of Australia's CEO, Craig Heidrich on the Editorial Board.
An important enabler in this journey for partners in the CRCLCL is to publish a Geopolymer Concrete Handbook as wider penetration of Geopolymer concrete within the construction industry affords a promising pathway to increase use of Low Embodied-Carbon construction materials.
Annual members and non-members were surveyed for CCPs generated, stored and sold during the reported period, which provides results for the calendar year; January to December 2015.
While lawmakers and environmental authorities are fixated on fly ash (FA) a potential hazard, many understand that the by-product is ‘A valuable resource.’ Duke University researchers explain that key components of technologies such as smart phones and electric car batteries include rare earth elements, which are found in abundance on the micro level in multiple FA ponds near Duke University in North Carolina.
The Research and Development team within LWP Technologies Limited has been testing Queensland-sourced FA at the pilot plant and the results from their work have been very positive and supportive of the path to commercialising cost effective FA based proppants for use in oil and gas hydraulic fracturing.
The chemically treated fly ash has gained the name OOPS and once it has absorbed oil from an oil-water mix, it floats on the surface of the water as a sticky substance that can be easily collected and transported and it can also be re-used in Coal-fire furnaces as fuel to generate heat and energy, once saturated.
The correlation between the amount of coal burnt and temperature is often strong and highly linear and this year North America’s winter rewrote the record books and was the hottest winter period ever documented. With temperatures averaging more than 5 degrees over the 20th century average. What does this mean for concrete manufactures and other Fly Ash users?
The Tennessee Valley Authority (TVA) has been responsible for the cleanup of the U.S Tennessee Kingston plant spill and eight (8) years on, the team are doing great. In the initail planning stage the team grouped engireers together to develop an innovative method of storing the fly ash.
Australia will be one step closer to achieving its environmenal sustrainability targets if we can effectively manage new industries using by-products as resources from old industries. It is in this space that an Australian fly ash industry may emerge, bringing with it innovative leaders and entrepreneurs to incorporate fly ash as an integral part of their business.
The burning of coal to make electricity creates two major by-products, fly ash and CO2 from smoke stacks. The ADAA and its members are currently doing everything possible to increase the utilisation of fly ash in the hopes of lessening the impact of burning coal on the environment. Although the utilisation of fly ash has been progressive, CO2 has been continuously viewed as a nuisance. Until now…
US based company, Southern Research is using $1 million in federal funding to develop and test a method to extract valuable rare earth elements (REEs) from coal fly ash, the minuscule waste particles captured by anti-pollution devices in coal-fired power plants. REEs are a series of chemical elements found in the Earth’s crust that are widely used because of their special properties. Increasing interest and research is being conducted into extract these elements from coal combustion products (Coal ash).
