  • 1049 Coal and Fly Ash - Final - Application Note

    The level of mercury found in coal can vary dramatically. Using clean fuels may be critical in satisfying emission requirements for the Mercury Rule of the Clean Air Act (CAA). Also, the monetary value of the fly ash residue resulting from the combustion of coal may be inversely proportional to its mercury content. The Hydra-C Direct Mercury Analyzer provides fast, simple and convenient analyses ...

  • 1901 HgENV Coal Fly Ash NIST 1633c - Technical Note

    This technical note describes the analysis of Coal Fly Ash (NIST 1633c) by EPA 7471B on the QuickTrace® M-7600 mercury analyzer. The analysis utilized a reduced internal diameter (ID) tubing for the stannous chloride (SnCl2), sample and waste lines. This configuration reduces reagent and waste and is validated in Application Note: AN1905 – Green Chemistry: Decreased Reagent Consumption ...

  • Class F Fly Ash Increases Resistance to Sulfate Attack - Technical Bulletin

    Sulfate attack is a two-phased process. Sulfates combine with calcium hydroxide generated during cement hydration to form calcium sulfate (gypsum). The volume of this gypsum is greater than the sum of its components causing internal pressure and expansion, which fractures the concrete. Then aluminate compounds from portland cement react chemically with sulfates and calcium to form a compound ...

  • Strength of Fly Ash Concrete - Technical Bulletin

    Compressive Strength: Strength gain contributed by portland cement occurs very rapidly at early ages up to about seven days, after which it slows markedly. Strength development contributed by fly ash occurs through chemical combination of reactive fly ash glass with calcium hydroxide generated by hydration of portland cement. This process is called pozzolanic ...

  • Fly Ash in Hot Weather Concrete - Technical Bulletin

    When the Mercury Goes Above 80°F and as placed concrete temperatures rise above 85°, a complex set of problems must be dealt with. The good news is, simple adjustments to the concrete mix or to construction practices may prevent these potential problems. Hot weather has been defined as any period of high temperature in which special precautions need to be taken to ensure proper handling, ...

  • Fly Ash in Controlled Low Strength Material - Technical Bulletin

    Controlled Low Strength Material (CLSM), an easy-to-place, flowable material consisting of fly ash, cement, sand, water, and 8-25% entrained air, is a slurry when placed and a low-strength engineered material when hardened. It is self-leveling, so it requires no compaction or vibration. The compressive strength can be designed to range from 0.35 MPa (50 psi) to 8 MPa (1200 psi). With compressive ...

  • Fly Ash for Architectural Concrete - Technical Bulletin

    Modern fly ash production and use is an integral part of concrete construction. Architects and structural engineers routinely design concrete mixes with fly ash for a wide range of structures, roadways, marine and high strength applications. Proven improvements in durability, permeability, shrinkage and long term strength gain yield better quality ...

  • Fly Ash Types & Benefits - Technical Bulletin

    The American Society for Testing and Materials (ASTM) defines pozzolan as “a siliceous or siliceous and aluminous material, which in itself possesses little or no cementitious value, but will, in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form compounds possessing cementitious ...

  • Energy Savings & Life Cycle Impacts of Fly Ash Use - Technical Bulletin

    In June 2008, the US Environmental Protection Agency, in conjunction with the US Department of Transportation and the US Department of Energy, presented a report to Congress entitled “Study on Increasing the Usage of Recovered Mineral Components in Federally Funded Projects Involving Procurement of Cement or Concrete to address the Safe, Accountable, Flexible, Efficient Transportation ...

  • Fly Ash for Concrete Pipe Manufacturing - Technical Bulletin

    Concrete pipe is made by essentially two different processes, one using extremely dry concrete mixtures and the other using plastic concrete mixtures. Dry cast concrete pipe is produced utilizing mechanical and/or vibratory compaction to consolidate dry concrete into a form. The form is removed from the pipe as soon as the casting is finished. With removal of the form, the green pipe is carefully ...

  • Fly Ash Increases Resistance to Freezing and Thawing - Technical Bulletin

    Freeze/Thaw Deterioration Begins when water enters voids in concrete. Leaching of calcium hydroxide, producing the hydration of portland cement, provides greater voids for water to occupy, thereby aggravating the rate of deterioration. Upon freezing, this water expands in volume 9%, generating pressures of 30,000 ...
