  • Ester man experiments with coal fly ash

    (Newsminer.com 07-29-2013) FAIRBANKS — Fairbanks has an abundance of coal fly ash, the byproduct of Interior Alaska’s many coal-fired power plants, and few places to put it.

  • CRN Looks at Future of Fly Ash

    (Electric Co-op Today 07-08-2013) Electric cooperatives and other utilities in the United States are trying to identify more potential uses for fly ash to make sure abundant supplies of coal remain part of the nation’s energy resources. Basin Electric Power Cooperative’s Leland Olds Coal Station near Stanton, N.D., is among the coal-based power plants generating electricity.

  • The Ancient Romans Were Better At Making Sustainable Concrete Than We Are

    (US News & World Report 06-04-2013) An ancient concrete mixture could be better for the environment and just as strong as modern mixtures. The secret to making sustainable, strong concrete may have been at the bottom the Mediterranean Sea for the past 2,000 years: Researchers believe that the ancient Romans created concrete that is more environmentally friendly and durable than modern cement.
     

  • Bill introduced to improve coal ash residuals legislation

    (Power Engineering 06-04-2013) Newer legislation that would set up a state-based regulatory program to regulate the disposal and management of coal combustion residuals and encourage reuse was introduced in the House of Representatives on June 3. Rep. David McKinley (R-W.V.) introduced the bill during a meeting of the Energy and Commerce Committee. The Subcommittee on Environment and the Economy will mark it up later in the week.
     

  • EGAT places artificial coral reef at the Sirindhorn International environmental Park

  • Rainy season first real test for artificial reefs

    (The Nation Multimedia.com 05-17-2013) Thailand-The rainy season will be the first real test for the artificial reefs placed in shallow waters along the coast of Phetchaburi's Cha-am district as they begin their mission of preventing coastal erosion. The reefs, which are partially made from lignite fly ash, were placed along the coastline on Wednesday. "This artificial reef will have to prove itself," community leader Chairat Tabtong said, adding that though he welcomed the initiative, he still had reservations.

  • Self-Compacting Concrete made with Ash from Combustion of Olive Pruning Residue Pellets

    (AzoBuild 05-03-2013) University of Granada researchers have successfully manufactured self-compacting concrete using ash from the combustion of olive pruning residue pellets. Due to its plasticity and cohesion, this type of concrete needs no compaction when used in construction and has many advantages over conventional concrete, resulting in considerable savings of time and money.

  • Concrete Moves for Carbon Reduction

    (The Construction Index 04-12-2013) Ash produced at coal-fired power stations is helping to improve the sustainability of concrete. Dr Robert Carroll from the UK Quality Ash Association explains how. Concrete is one of the most important construction materials there is. The worldwide use of concrete today is more than double that of wood, plastic, steel and aluminium combined. But it is one of the most carbon intensive industries on the planet and it is under increasing pressure to change the way it operates.

  • Nashik may get a fly ash cluster project

    (The Times of India 04-08-2013) NASHIK: A brick-manufacturing cluster project for small units engaged in making bricks from fly ash is likely to come up in Nashik soon. The District Industry Centre (DIC), Nashik, is planning to set up the cluster project by putting up a common facility centre for the units engaged in making bricks from fly ash, generated from the thermal power station at Eklahare near Nashik.
