This book was released on 1958 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty materials, representing eight different classes of mineral admixtures, were evaluated, using both chemical and mortar-bar test methods, for their effectiveness in preventing excessive expansion of concrete due to alkali-aggregate reaction. The criteria of the chemical tests are examined, and the test results were compared with the mortar-bar test results. All results were compared with those obtained by two other laboratories. It was found that the chemical tests cannot be used with reliance to evaluate effectiveness, and that the mortar-bar test procedure needs improvement to increase its precision. Each of the replacement materials evaluated will prevent excessive expansion if a sufficient quantity is used. Correlations were found between effectiveness and: fineness, dissolved silica, and percentage of alkali retained by reaction product. Calculations were made that suggest that the minimum quantity of each material required for effective prevention of excessive expansion ranged from 10% for the synthetic silica glass to 45% for one of the slags. By groups these calculated minimum percentages were: calcined shales, 19 to 29; uncalcined diatomite, 22; volcanic glasses, 32 to 36; slags, 39 to 45; fly ashes, 40 to 44.

Download or read book Proposed New Test Procedure for Measuring Alkali Silica Expansion Produced by Hydraulic Cement written by LJ. Struble and published by . This book was released on 2000 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there are several standard tests for measuring alkali-silica expansion produced by an aggregate, there is only one test suitable for measuring expansion produced by the cementitious material (C 441, Standard Test Method for Effectiveness of Mineral Admixtures of Ground Blast-Furnace Slag in Preventing Excessive Expansion of Concrete Due to the Alkali-Silica Reaction). This mortar test uses Pyrex glass as the standard reactive aggregate. A new test has been developed to overcome these deficiencies. Also a mortar test, it utilizes Vycor glass rather than Pyrex glass and a procedure that does not produce condensation on the bars, which causes leaching of alkalies from the mortar. The test has recently been adopted by ASTM as a provisional standard to determine whether hydraulic cement produces deleterious expansion when combined with alkali-reactive aggregate in concrete.

Book excerpt: This book presents an in-depth approach to concrete ingredients and their relationships to concrete by discussing their properties, pertinent test methods, specifications, proper use and selection, and solutions to problems in practice. The approach is practice oriented, and the book assists in the improved application of concrete through a thorough understanding of its ingredients. This is aided by the discussion of certain fundamental aspects and relationships in quantitative forms, and by also presenting the interpretation of research and experience. An extensive bibliography is included.The book is a current, organized summary of knowledge concerning concrete-making materials, which will enable the engineer/user to make the best possible product using these materials.

Book excerpt: The amount and variety of waste that humanity dumps in landfill sites is nothing short of a scandal, believes Rafat Siddique, of Deemed University in Patiala, India. Instead, we ought to be building new homes out of it! Siddique shows in this important book that many non-hazardous waste materials and by-products which are landfilled, can in fact be used in making concrete and similar construction materials.
