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.
Coal combustion residuals are often viewed as a troublesome burden—a waste product that coal-fired power plants struggle to deal with. Much has been written about disposal management strategies, and a lot of money is spent annually on landfills and monitoring. But in many cases, disposal is not the best option; beneficial use of the material could save money and reduce liability.
This article provides an interesting perspective on We Energies journey towards 100% benefical reuse of all coal combustion products from its faciliies, along with some novel developements and applications.

Fibres in different types and forms have an unquestionable, profound effect on the performance of concrete structures. Put simply, high performance concrete does not exist without the use of fibres.
World Of Concrete (WOC), will be the first international event of the year for the CCP industly. The conference will showcase producers of concrete and masonry products whilst also including industry talks from leaders in concrete reinforcement.
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?
Now in its tenth year, the Institute of Quarrying Australia (IQA) and Cement Concrete Aggregates Australia (CCAA) have joined forces once again to present CMIC16 as the leading conference for the construction materials industry.
Dear Readers, please note that the following draft’s public comment period is due to close in three days:
“Fly ash is not waste, it is a valuable resource.” These findings “promise to lift fly ash perceptions in the world” - Kunigal Shivakumar (director of Composite Materials Research Centre).
The 2017 Australian Society for Concrete Pavements Conference will be held at Mantra on Salt beach, Kingscliff NSW on 17 & 18 July 2017. The "Call for Abstracts" has been broadcast and submissions close on 19 August 2017.
NSW transport and road funding highlights in 2016-17 includes, $2.9 billion allocated to WestConnex; $2.1 billion on upgrades to key regional highways; and $2.7 billion to deliver Sydney Metro (including $1.3 billion for Sydney Metro Northwest and $1.4 billion for Sydney Metro City and Southwest).
The Ash Development Association of Australia is currently drafting content for the upcoming edition of Coal Ash Matters and we would love to hear your ideas and contributions!
Queensland based company Coretrack Ltd has developed a new ceramic proppant made predominantly from fly ash, which are lightweight and inexpensive compared to its predecessors. The innovative proppant allows for deeper 'fracking' and can withstand higher pressures than traditional ceramic proppants.
The Concrete Institute of Australia (CIA) will be answering the question of "Why does concrete do the things it does?" For a product that in its simplest form consists of only 4 materials, it is an incredibly complex and interesting material. Get it right, and you can achieve amazing results. Get it wrong, and the results can be catastrophic.
The forum addresses a range of topics relating to the design, specification, construction and maintenance of concrete pavements. There will be a report on the trial of the use of recycled concrete in the select material zone and heavily bound sub-base on an upcoming project to reconstruct and widen a section of the M1 Motorway.
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.
Jamie North combines the co/by products of industry and native Australian flora species to create sculptural installations that explore the simultaneous concurrence and conflict between man-made architectural structures and the biological world.
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 following Standards Australia publication has been released: AS 1141.22-2008 Amd 1 - Methods for sampling and testing aggregates - Wet/dry strength variation
Concrete 2017 will be the 28th Biennial National Conference of the Concrete Institute of Australia and will be held in the beautiful city of Adelaide, South Australia.
Please note that the following amendments were published on the 8th April 2016.
This year the Asian Coal Ash Association will hold the Coal Ash Asia 2016 Conference from the 22-26 September in Shouzhou, Shanxi Province, China. Coal Ash Asia 2016 features 3 days of conference, seminars, exhibition and business matching.
