Traditionally, concrete specifications have been specified prescriptively, for example by defining the minimum cement content and maximum water-to-cement ratio to provide 

In a ground-breaking study, titled "Emerging Trends in the Recovery of Ferrospheres and Plerospheres from Coal Fly Ash Waste and Their Emerging Applications in Environmental Clean-up," researchers have uncovered new avenues for the effective recovery of valuable materials from coal fly ash waste. This innovative research not only offers promising solutions for managing coal fly ash waste but also presents opportunities for environmental clean-up.

Federal Budget Announces Net Zero Authority Funding

 Lafarge Canada and TransAlta Corporation have formed a partnership to promote low-carbon concrete projects in Alberta. As part of this collaboration, they will use fly ash, a waste product from TransAlta's discontinued Canadian coal-fired electricity operations west of Edmonton, to replace cement in concrete production. This initiative is aimed at reducing carbon emissions and making better use of waste materials.

Arcadis Use Fly Ash in JFK Airport Redevelopment

Funding Announced for Carbon Recycling

ADAA member Stanwell Corporations are continuously diverting hundreds of thousands of tonnes of coal combustion products (CCP) from landfill by treating it as a resource instead of as a waste. 

Fly ash has stepped up to the challenge once again, being utilised as the specialised concrete for an innovative bridge-replacement project in Orlando, Florida.

The ASTM Committee C09 on Concrete and Concrete Aggregates in the US, has just approved revision of the ASTM C618 - Standard Specification for Coal Ash and Raw or Calcined Natural Pozzolan for Use in Concrete, in a unanimous vote, to include harvested coal ash and bottom ash. 

Coal ash is continually becoming a substantial asset that propels positive environmental, economic, and performance benefits to various high-value-added applications. Therefore, it is no wonder the beneficial use of coal ash continues to grow with approximately 60% of coal ash produced during 2021 being recycled.

Flying out of Brisbane Airport has never been so environmentally friendly..until now. A recent renewable energy agreement between ADAA member Stanwell Corporations and Brisbane Airport Corporate (BAC) has been established, enabling Brisbane Airport to be powered by 100% renewable energy. 

The standard relating to the sampling and testing of coal fly ash and natural pozzolans has had a two-item ballet published by the ASTM Subcommittee C09.24 on Supplementary cementitious Materials. The American Coal Ash Association Technical Committee are currently working to submit advice on the ballet, which is open until 2nd December 2022. 

The sunshine state is getting even brighter thanks to the new Cross River Rail project. Made up of 10.2 km of rail line including 5.9km of twin tunnels running under the Brisbane River and CBD, the project aims to transform the way Queenslanders travel across the whole of South East Queensland.

The Standards Australia Research and Analysis team would like to invite you to the insightful webinar that will explore what it will take for this sector to realise the immense opportunities for growth and digital transformation.

Latrobe Magnesium is on the verge of developing Australia's first plant, extracting magnesium metal from brown coal fly ash and ferro-nickel slag, using their state-of-the-art patent hydromet technology. 

TfNSW would like to invite you to workshop 04: Environmental Sustainability - Standards and Specifications. 

ADAA member Latrobe Magnesium (LMG) are using a world-first process of combined hydromet/thermal reduction for magnesium extracted from fly ash. 

Concrete Institute of Australia's Biennial National Conference has extended the abstract submissions to 13 October 2022 at 11:59 (AWST). 

A North American Product Category Rule (PCR) has been created for supplementary cementitious materials (SCMs), the first step in developing Environmental Product Declarations (EPDs).

A report by The University of New South Wales has been developed whereby findings are presented on the performance of High-density Geopolymer Concrete (GPC) used in the fabrication of Hanbar amour units and placed at Port Kembla's Northern Breakwater. 

Coal continues to be the largest energy source for electricity generation within Australia, and accordingly significant volumes of CCPs are produced, used, and stored annually. ADAA member, Stanwell is at the forefront of developing uses for CCPs, attributing its success to the skill and dedication of its workforce.
