Technology shears cost of grinding fly ash to match silica fume performance

Sources: CP staff; IgniteIP, New York

By Don Marsh

A New York investor announced at World of Concrete (January 18–21, Las Vegas) technology economizing the grinding of fly ash, or secondary grinding of portland cement, to 3- or 1-micron median particle sizes. With $30–75/ton processing plus $20–100/ton raw feed (fly ash, Type I/II portland cement) costs, the technology can yield premium binding agents whose performance properties in concrete and grouts match those of ultra-fine high-reactivity metakaolin or silica fume—typically commanding $300–$700/ton.

Environmentalists move to nix fly ash from LEED point consideration

Sources: CP staff; Public Employees for Environmental Responsibility (PEER), Washington, D.C.

By Don Marsh

Environmentalists’ latest weapon to undermine the use of coal in power generation follows a curious trajectory: The U.S. Green Building Council’s public comment process for LEED [Leadership in Energy and Environmental Design] rating system revisions. A group comprising federal and state environmental and law enforcement agency officials, PEER contends that construction-grade fly ash—the most widely used coal combustion residual (CCR)—should not qualify as a recycled material in the LEED rating system. It conveyed that position to the USGBC, which on January 19 will close the first of two public comment periods this year toward a new LEED version in fall 2012.
