Microsoft are introducing lower-carbon concrete mixes into their builds, with the help of fly ash and slag.
The winner of the 2023 ‘Good Design Award for Sustainability’ implemented the use of fly ash to help reduce CO2 emissions in their new ‘Erosion Mitigation Units’ (EMU).
World of Coal Ash (WOCA) is an international conference organised by the American Coal Ash Association (ACAA) and the University of Kentucky Centre for Applied Energy Research (UK CAER).
World governments are taking the lead in pursuing net zero, with more than 140 countries having stated their intentions of reaching net zero by the year 2050.
Fuel ash from burning coal in coal-fired power stations is being put to good use in the construction industry, after advancements in technology have helped in assisting the relocation and transformation of this by-product.
Adbri have released independently verified, transparent, and comparable information about the environmental impacts of their products through the development of Environmental Product Declarations (EPD).
The Cement Association of Canada (CAC) along with member producers and downstream partners has released Concrete Zero, an action plan for carbon emissions reduction measures up and down the industry’s value chain. The document will build on formal CO2 benchmarks that CAC and Innovation, Science and Economic Development Canada officials outlined last Autumn in a ultimate goal to reach net zero by 2050, cement and concrete producers detail the following 5 priority areas in the new action plan:
The Polish CCP Union (Polska Unia UPS) and its partner European Coal Combustion Products Association (ECOBA) in cooperation with Warsaw University of Technology held the International Conference EUROCOALASH on May 22-24, 2023 in Warsaw, Poland.
Join industry leaders in Myrtle Beach, South Carolina for the workshop titled, Exploring the Current Opportunities in Coal Ash. Hosted by the American Coal Ash Association and the University of Kentucky Center for Applied Energy Research,
ADAA CEO Craig Heidrich's chat with Smartcrete.
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.
"Rice University's Breakthrough: Purified Fly Ash in Cement for Stronger and Sustainable Concrete"
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.
