Download or read book Fly Ash in Concrete written by R C Joshi and published by CRC Press. This book was released on 1997-11-13 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since it was first recognized as a mineral admixture for concrete in the 1930's, fly ash has been the subject of worldwide study as researchers work to maximize its economical and environmental benefits. In recent years, investigations have focused on the physical, chemical and mineralogical characteristics of fly ash and their specific correlation to the performance of concrete. This book collects the latest results from these various studies and offers a complete review of the advantages of fly ash as an admixture in concrete, including strength development and improved chemical resistance and durability. A review of the current international standards on fly ash usage is provided, in addition to an extensive reference list and a complete survey of various other fly ash products, such as bricks, mineral wool and gypsum wall boards, as well as the use of fly ash in waste management.

Book Synopsis Optimizing the Use of Fly Ash in Concrete by : M. D. A. Thomas
Download or read book Optimizing the Use of Fly Ash in Concrete written by M. D. A. Thomas and published by . This book was released on 2007 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The optimum amount of fly ash varies not only with the application, but also with composition and proportions of all the materials in the concrete mixture (especially the fly ash), the conditions during placing (especially temperature), construction practices (for example, finishing and curing) and the exposure conditions. This document discusses issues related to using low to very high levels of fly ash in concrete and provides guidance for the use of fly ash without compromising the construction process or the quality of the finished product. The nature of fly ashes including their physical, mineralogical and chemical properties is covered in detail, as well as fly ash variability due to coal composition and plant operating conditions. A discussion on the effects of fly ash characteristics on fresh and hardened concrete properties includes; workability, bleeding, air entrainment, setting time, heat of hydration, compressive strength development, creep, drying shrinkage, abrasion resistance, permeability, resistance to chlorides, alkali-silica reaction (ASR), sulfate resistance, carbonation, and resistance to freezing and thawing and deicer salt scaling. Case studies were selected as examples of some of the more demanding applications of fly ash concrete for ASR mitigation, chloride resistance, and green building.

Book Synopsis Optimization of Fly Ash Replacement in High Volume Fly Ash Concrete by :
Download or read book Optimization of Fly Ash Replacement in High Volume Fly Ash Concrete written by and published by . This book was released on 1991 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes research performed to determine the optimum fly ash content in the high volume system. Optimum is defined as the fly ash content for a given water-cementitious ratio which produces the most economical concrete on the basis of cost per MPa. Three series of concrete mixtures were evaluated. Mixtures were performed at a water cementitious ratio of 0.25, 0.27 and 0.32 at fly ash replacement (based on total cementitious) of 50, 55, 60 and 65 percent. The fly ash content varied from 45 to 60 percent for these tests. Materials included Portland cement; low calcium fly ash from the coal fired thermal generating plant in Lingan, NS; coarse aggregate from a Halifax quarry; fine aggregate (natural sand); superplasticizer; air-entraining mixtures; and concrete mixtures. Compressive strength specimens were cast for laboratory storage and testing at 3, 7, 28, and 91 days. Three specimens were tested at each age.
Book Synopsis Handbook on fly ash in concrete by : Dietmar Lutze
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.

Book Synopsis Metakaolin and Fly Ash as Mineral Admixtures for Concrete by : Leonid Dvorkin
Download or read book Metakaolin and Fly Ash as Mineral Admixtures for Concrete written by Leonid Dvorkin and published by CRC Press. This book was released on 2021-11-04 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with modern theoretical concepts related to the impact of fly ash and metakaolin admixtures on structure formation processes of concrete. Results of the effect of fly ash, metakaolin and their composition on properties of self-compacting and self-leveling concrete are presented. Based on mathematical models, obtained using mathematical experiments planning methodology, the impact of the main factors and their combination on workability, strength and other properties that determine efficiency and durability of concrete are analyzed. Using calculated dependencies, a methodology for designing optimal compositions of concrete containing active mineral admixtures and superplasticizers is proposed. Features of industrial production of concrete for the proposed compositions are discussed. The book is intended for specialists working in the production of concrete and reinforced concrete products and elements. It can also be used by construction engineers to design compositions of cost-effective self-compacting and self-leveling concrete as well as to determine the rational direction of using technogenic raw materials like ash and metakaolin.

Download or read book Experimental use of fly ash concrete in prefabricated bridge deck slabs written by and published by . This book was released on 1987 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic cement concretes with and without fly ash were investigated to assess the suitability of using fly ash in bridge-deck concrete. Eight prefabricated concrete slabs were prepared: four were control and the remaining contained fly ash. They were used for widening two bridge structures. Slump, air content, and unit weight were determined on the freshly mixed concrete; compressive strength, permeability, absorption, freezing and thawing durability, and the air void system were determined for the hardened concrete. Depth of cover over the reinforcing steel was measured. After three winters of exposure, slabs were surveyed visually for cracks, scaling, and spalls. Half-cell readings were taken, and chloride samples obtained and tested. Fly ash concretes required a larger amount of air-entraining admixture than the controls to achieve the required air content. Although the 28-day strength tests showed that three of the four fly ash concretes did not achieve the required strength of 4,000 psi, the strength of all concretes exceeded 4,800 psi at 6 months when moist cured. The field evaluation after 3 years of winter exposure indicates that all concretes with fly ash are performing satisfactorily.
