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 Evaluation of Experimental Installation of Fly Ash Concrete in Louisa by : Hamdi Celik Ozyildirim
Download or read book Evaluation of Experimental Installation of Fly Ash Concrete in Louisa written by Hamdi Celik Ozyildirim and published by . This book was released on 1979 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to investigate the resistance of field concretes containing fly ash to damage from cycles of freezing and thawing as evidenced by scaling, based upon a reevaluation of a field project. In 1955 and 1956 an experimental sidewalk, curb and gutter installation made from concrete utilizing fly ash was placed in Louisa. In this installation two levels of fly ash content were used. In one mixture 20% of the cement by weight was replaced with fly ash and in another 33% of the cement was replaced. Air contents were approximately the same. A visual examination of the installation revealed that concretes containing fly ash exhibited more scaling than did the control mixture, with the mixture having the 33% replacement scaling the most. The internal structures of cores taken from all concretes (20% replacement, 33% replacement and the control) were in good condition and no internal damage from freezing and thawing could be observed. The compressive strengths of the cores were all satisfactory.

This book was released on 2018-02-15 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: When incorporated in concrete mixtures, fly ashes are known to influence both its fresh and hardened properties. An accurate and quick technique to predict the extent of this influence based on the characteristics of fly ash would be highly beneficial in terms of field applications. The current study was an attempt to quantify the effects of fly ashes on the properties of pastes as a function of: (a) the mean particle size of the fly ash particles, (b) their fineness and (c) their chemical composition. In addition, since the type and the amount of glass present in the fly ash significantly affect its reactivity, this property was also included in the investigation.Twenty different fly ashes (both, ASTM Class C and Class F), obtained from power plants in and around Indiana, were characterized during the Phase 1 of the study. The information collected included: physical characteristics, chemical composition and the amount and type of glass present. Phase 2 of the study consisted of evaluation of various properties of binary paste systems (portland cement with 20% of cement of fly replacement). The evaluated properties included: the set time, the heat of hydration, the strength activity index, the non-evaporable water content and the amount of calcium hydroxide formed at different ages.These results obtained from both phases of the study were used to build statistical models for prediction of previously evaluated properties for any hypothetical fly ash with similar characteristics. The models included only the most significant variables, i.e., those which were found to most strongly affect any specific property. The variables to be included in the model were selected based on the adjusted R2 values.As a result of the modeling process, it was found that the sets of statistically significant variables affecting the properties consisted of both physical and chemical characteristics of the fly ash and that the combination of these variables was unique for each property evaluated.
