Production of the cement used in concrete is a major source of greenhouse gas emissions, which is why some people have tried replacing it with fly ash. A new technique makes that fly ash more eco ...

Fly ash generated by coal power generation can be repurposed into superior-grade geopolymer concrete. However, a critical durability problem has been low resistance to alkali attack.

Engineers have developed a composite binder made primarily of fly ash, a byproduct of coal-fired power plants, that can replace Portland cement in concrete.

The cement industry generated approximately 1.6 billion tonnes of CO₂ in 2022, about eight percent of all global emissions.

Concrete is one of the main uses of recycled fly ash, since binders based on that waste material don't need the same high-temperature, energy-intensive processing that Portland cement does.

Scientists develop process to remove toxic heavy metals from coal fly ash, making for greener, stronger concrete. The road to a net-zero future must be paved with greener concrete, and Rice ...
