Cementless fly ash binder makes concrete 'green'

Rice University 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.

Researcher tests fly ash for stronger concrete

Portland cement has been around for more than 250 years as the binding material for concrete, mortar and stucco, but a Missouri University of Science and Technology researcher is studying ways to make concrete without the ...

New use for paper industry's sludge and fly ash in plastics

VTT Technical Research Centre of Finland examined, as part of the EU's Reffibre project, whether new industrial applications could be developed for various types of sludge and fly ash generated by the paper and board industry. ...

ESA releases statement on the dangers of invasive species

The Entomological Society of America (ESA) has issued a statement about the dangers of invasive species and the potential threats they pose to U.S. national interests by undermining food security, trade agreements, forest ...

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 ...
