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.

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.
