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 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.

Download or read book Use of Fly Ash in Concrete by State Transportation and Highway Departments written by Woodrow J. Halstead and published by . This book was released on 1980 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides a summary of replies to a questionnaire on the use of fly ash and blended cement (Type IP) in concrete. The questionnaire was directed to members of the Subcommittee on Materials of the American Association of State Highway Officials. The states' representatives on this subcommittee are usually the state materials engineers. The subcommittee also includes associate members from some of the provinces of Canada and some federal agencies involved in roadway or airport construction. Fifty-nine agencies responded to the questionnaire. These included all of the state highway and transportation departments, the District of Columbia, three provinces of Canada, and five federal agencies. Twenty-four agencies reported that they made no use of either fly ash added to the concrete as an admixture (FAC) or of concrete made with Type IP blended cement (IPC). The remaining 35 agencies permitted the use of either IPC or FAC, or both, usually at the option of the contractor. However, only 4 states had placed more than 100 lane-miles of FAC, and only two states had placed more than 100 lane-miles of IPC. This lack of large usage of FAC or IPC is believed to reflect a lack of significant economic incentives for use by a state or contractor under present circumstances. The initial capital investment for the required separate silos or storage bins for fly ash deters a small contractor from using FAC, as does the increased quality control testing. IPC is not attractive since the blended cement (Type IP) usually costs the same as regular portland cement. Accordingly, the more familiar product (regular portland cement) is selected for use when both types are available. The states making substantial use of either of FAC of IPC all report satisfactory performance. The primary control problem reported is that of assuring the proper amount of entrained air. When fly ash is used, more air-entraining agent is required to entrain the desired amount of air than is required for similar concrete "without fly ash. Prior approval of the source of the fly ash is required by almost all agencies. The specification most often cited by all agencies is ASTM Specification C618 Class F (fly ash). However, in all cases the loss on ignition is limited to a maximum of 6.0% in lieu of the 12.0% limit given in C618. Some state specifications also differ from C618 in the limitations on chemical composition but it is likely that all materials being used would meet C618 requirements, except where fly ash high in calcium oxide is encountered.

Book Synopsis The Use of Fly Ash in Highway Construction by : Vernon J. Marks
Download or read book The Use of Fly Ash in Highway Construction written by Vernon J. Marks and published by . This book was released on 1990 with total page 30 pages. 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.
