Radioactive contaminants found in coal ash

A new Duke University-led study has revealed the presence of radioactive contaminants in coal ash from all three major U.S. coal-producing basins.

Green concrete proves more durable to fire

Concrete made using an industrial by-product has shown better fire endurance than traditional concrete when exposed to fires of nearly 1000 degrees Celsius.

Unforeseen dioxin formation in waste incineration

Dioxins forms faster, at lower temperatures and under other conditions than previously thought. This may affect how we in the future construct sampling equipment, flue gas filtering systems for waste incineration and how ...

Fly ash builds green cement mixture

An eco-friendly cement, known as Alkali Pozzolan Cement (APC), containing a mixture of fly ash, dry lime powder and sodium sulphate under specific scaffolding conditions has been developed by Curtin University research.

Researchers develop new cement mortar from seagrass residues

Researchers at the University of Alicante have developed a new process for manufacturing concrete to achieve greater resistance. This is a new mortar based on Portland cement with the addition of the ashes retrieved from ...

Limestone powder enhances performance of 'green' concrete

Adding limestone powder to "green" concrete mixtures—those containing substantial amounts of fly ash, a byproduct of coal-burning power plants—can significantly improve performance, report researchers from the National ...
