Book Description
In 1982 the Iowa DOT allowed a successful bidder the option of submitting materials and proportions using fly ash to produce a portland cement concrete (PCC) paving mixture to meet a specified compressive strength. The contractor, Irving F. Jensen, received approval for the use of a concrete mixture utilizing 500 lbs. of portland cement and 88 lbs. of fly ash as a replacement of 88 lbs. of portland cement. The PCC mixture was utilized on the Muscatine County US 61 relocation bypass paved as project F-61-4(32)--20-70. A Class "C" fly ash obtained from the Chillicothe electric generating plant approximately 100 miles away was used in the project. This use of fly ash in lieu of portland cement resulted in a cost savings of $64,500 and an energy savings of approximately 16 billion BTU. The compressive strength of this PCC mixture option was very comparable to concrete mixtures produced without the use of fly ash. The pavement has been performing very well. The substitution of fly ash for 15% of the cement has been allowed as a contractor's option since 1984. Due to the cost savings, it has been used in almost all Iowa PCC paving since that time.

Book Description
The drive to develop more sustainable materials has made fly ash a valuable raw material in many different applications. Comprehensive and authoritative, Handbook of Fly Ash highlights the latest research efforts to develop the properties of fly ash to maximum utility while safeguarding the environment. This book takes an interdisciplinary approach to the research into the classification and compositions of various types of fly ash, such as bottom ash and boiler slag, special classes of fly ash, and their sources around the globe. This is followed by a discussion of fly ash-reinforced composites, such as elastomer-based composites and metal matrix composites. This book also covers a wide range of applications of fly ash in cement, concrete, bricks and blocks, road construction, wastewater treatment, and scrubber sludge solidification. - Highlights the recent developments in the utilization of fly ash including its preparation, functionalization, properties, and handling. - Places a focus on a wide variety of fly ash applications including recent innovations, such as alkali-activated binder, polypropylene composite, and geopolymer concrete. - Includes comprehensive coverage of the characteristics of fly ash with a particular focus on health hazards if it is not properly disposed. - Discusses fly ash-reinforced composites, such as polymer/elastomer-based composites and metal matrix composites.

Book Description
This report is essentially a synthesis of pertinent information concerning the use of fly ash as an ingredient in concrete for highway construction. It has been prepared to provide a basis for an adequate response by the Department of Highways and Transportation to requirements of the Resource Conservation and Recovery Act and the Environmental Protection Agency pertaining to the use of this by-product in concrete purchased with federal funds. Special attention is given to the quality control and acceptance problems associated with highway usage of fly ash concrete, with emphasis on problems relating to air entrainment. References to the background literature that established the suitability of fly ash as a pozzolan and its use in concrete are The requirements for fly ash as set forth in ASTM Specification C618 are reviewed and the- characteristics to be expected from concrete containing fly ash are discussed. It is recommended that the Virginia Department of Highways and Transportation permit the use of fly ash in concrete at the option of the contractor with prior approval by the state. It is also recommended that suitable specifications for this use be prepared following the guidelines previously recommended by the Concrete Research Advisory Committee.
