Download or read book Use of Fly Ash in Concrete written by Woodrow J. Halstead and published by Transportation Research Board National Research. This book was released on 1986 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis summarizes available information concerning the use of fly ash in hydraulic-cement concrete, and attempts to establish consensus concerning a number of applications relating to highway construction. Fly ash marketing procedures are briefly reviewed, and the amount of fly ash now being used is summarized. The results are reported of a questionnaire survey of the status of the use of fly ash concrete (FAC) in each state of the U.S. and the provinces of Canada. There is an increase in FAC use since 1980. This trend is aided by the development of a flyash industry. Trends also indicate a developing technology that will be oriented around performance of the hydraulic cement concrete. Currently, most states view the proportioning of of FAC from the standpoint of the amount of portland cement to be replaced by the fly ash and have maximum replacement limits. It has been noted that the same fly ash with different cements may react differently and develop different early and ultimate strengths. The need is emphasized for preliminary tests to establish optimum proportioning of ingredients in the concrete using materials from the sources to be supplied to the job.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Handbook on fly ash in concrete written by Dietmar Lutze and published by Verlag Bau+Technik. This book was released on 2013-03-20 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: When used as an addition and binder component, fly ash has become an indispensable construction material for many concrete applications. The conditions produced in power stations when firing fine pulverized coal result in the formation of a reactive, flour-fine, pozzolanic mineral material from the accompanying rock in the coal. Owing to its specific characteristics it has a positive impact on the properties of fresh and hardened concrete and facilitates cost-effective production of high-grade, durable concretes. The authors of this handbook have combined the latest discoveries from the field of research with practical experience of the use and effects of fly ash in concrete. This handbook provides the necessary information and makes interesting suggestions for selective use of fly ash in concrete.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
