Fly ash in concrete— no worries

(Structural Engineer April 2012) For years structural engineers have incorporated fly ash into their concrete mix designs to produce high quality concrete, and its use as a cement replacement is increasing as engineers seek to reduce CO2 emissions. Questions have arisen recently over the appropriateness of incorporating fly ash into concrete due to concerns about the trace amounts of mercury found in the byproduct of coal combustion.

Transportation Bill Passes With Fly Ash Amendment

(Wheeling News-Register 4-19-2012)  The U.S. House on Wednesday voted to extend federal transportation funding through September, a measure that included Rep. David B. McKinley's "fly ash" bill and another provision permitting construction of the Keystone XL pipeline. House Resolution 4348 was approved by a vote of 293-127, with local Reps. McKinley and Shelley Moore Capito, both R-W.Va.; Bob Gibbs and Bill Johnson, both R-Ohio; and Nick Rahall, D-W.Va., all voting in favor.
 

McKinley applauds fly ash addition to transportation bill

(The State Journal 4-18-2012) Rep. David B. McKinley, R-W.Va. added an amendment supporting the use of coal ash byproducts to the Surface Transportation Extension Act on April 18. Coal ash, the byproduct of combustion of coal, can be used as a building material for highways, bridges, concrete and other uses. His amendment to the House transportation bill would block the EPA from regulating the material.
