In 2008 a fly-ash dam collapsed in the U.S., threatening the surrounding community. ❋ Unknown (2010)
Our relentless pursuit of coal has already produced fly-ash spills that have done more damage to our environment than the Exxon Valdez. ❋ Unknown (2010)
The green is sculpted with 1.5 million tons of coal fly-ash. ❋ Unknown (2010)
In markets where there is high urban growth, there tends to be less of a fly-ash liability because the fly ash is recycled into roads, said ❋ Unknown (2010)
The concrete is often made with foam, fly-ash or other waste materials to make it lighter as well as cheaper. ❋ Unknown (2009)
In total, some 5.4 million cubic yards of waterlogged fly-ash -- enough to fill 450,000 standard dump trucks -- flooded into the river, making this the largest environmental disaster of its kind in U.S. history. ❋ Scott Barker (2009)
It was a wall of fly-ash sludge, a waste product of coal combustion from a nearby power plant. ❋ Scott Barker (2009)
"The second generation of farmers was trained to execute construction projects such as fabrication units for windows, manufacturing of fly-ash bricks and landscaping," Magar says. ❋ Unknown (2009)
Stranger still, the party that prides itself on fiscal responsibility neglected to mention that switching the Capitol Power Plant to natural gas will eliminate significant costs to transport and store coal, and to clean up coal's fly-ash and waste. ❋ Unknown (2009)
An aerosol of partly burnt pesticide waste around which microparticles of fly-ash or clay coalesced as the plume cooled would have a similar elemental composition to that reported. ❋ Unknown (2006)
Good quality and high strength bricks can be produced from fly-ash sand and lime as binder. ❋ Unknown (1995)
The fly-ash building bricks are usable in all types of brick masonry works and can substitute the conventional burnt clay bricks in nearly all application. ❋ Unknown (1995)
Other advantages of clay fly-ash bricks are reduction in the drying shrinkage and about 15 to 25 per cent of the weight of the bricks with better thermal insulation. ❋ Unknown (1995)
The mixture of fly-ash sand or bottom ash and binder in suitable proportion is moulded into bricks under pressure which is further cured by autoclaving. ❋ Unknown (1995)
The quality of fly-ash bricks are found to be superior to conventional burnt clay bricks in some respects such as water absorption, crushing strength etc. ❋ Unknown (1995)
According to Mintec's Dr Johann Engelbrecht, the CSIR had done some work on gaseous emissions, but these were only one component of air pollution - the other being particulates - such as dust and fly-ash. ❋ Unknown (1995)
The blending of certain carbonaceous materials such as granulated slag, fly-ash and other pozzolanas with cement makes it possible to produce more cement from the same amount of clinker and, thus, reduce the final consumption of energy per ton of cement produced. ❋ Unknown (1995)
