Available in PDF, EPUB and Kindle. Book excerpt: Literature on the quality of water for mixing and curing concrete indicates that relatively few investigations on this subject have been conducted. It seems to have been generally agreed that water fit to drink was fit to use in concrete mixing, and even fewer limitations were applicable to curing-water quality. Tests were conducted by the Missouri River, South Atlantic, and Ohio River Division Laboratories, and the Waterways Experiment Station to determine the effects of pH values of water on the strength of concrete and the staining properties of elements found in water. It was found that various contaminants can render distilled water unfit for mixing or curing concrete. It is also indicated that pH does not provide a basis for specifying quality of mixing water. A procedure for evaluating curing waters for staining properties is presented in appendix A in which, for a preliminary evaluation, 3000 ml of the water are evaporated, and for a complete test 3 gal are evaporated. A digest of the literature is given in appendix B. (Author).
Download or read book Chapter 43 Mixing and Curing Water for Concrete written by WJ. McCoy and published by . This book was released on 1978 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper is concerned primarily with the significance of tests of various types of waters for mixing and curing concrete and makes no attempt to include the effect of quantity of mixing water. Almost all natural waters, fresh waters, and waters treated for municipal use are satisfactory as mixing water for concrete if they have no pronounced odor or taste. Because of this very little attention is usually given to the water used in concrete, a practice that is in contrast to the frequent checking of the cement and aggregate components of the concrete mix.

MCCOY, THEN DIRECTOR OF RESEARCH for Lehigh Portland Cement Company, wrote the first version of this chapter for ASTM STP 169. For ASTM STP 169A, Mr. McCoy revised his chapter and added information on typical municipal water analyses, tolerable concentrations of impurities, the effects of sugar in mixing water, and the effects of water hardness on concrete air content. He also added several new references. For ASTM STP 169B, Mr. McCoy, then Director of Cement Technology for Master Builders, made only minor changes to the ASTM STP 169A version of the chapter. This current version is essentially Mr. McCoy's (now deceased) chapter with limited updating. There has been very little new technology published regarding mixing and curing water for concrete. The ASTM STP 169D edition as prepared does, however, reflect recent standards developments promulgated by ASTM Subcommittee C09.40 and Committee C09.

Book excerpt: Curing is one of those activities that every civil engineer and construction worker has heard of, but in reality does not worry about much. In practice, curing is often low on the list of priorities on the construction site, particularly when budgets and timelines are under pressure. Yet the increasing demands being placed on concrete mixtures also

Download or read book Cracking Control on Early Age Concrete Through Internal Curing written by Dejian Shen and published by Springer Nature. This book was released on 2023-07-10 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is written based on the author's research on the assessment, control, and repair of cracking of early-age concrete in the recent decade. The technique of internal curing for increasing cracking resistance of early-age concrete is further developed through experimental and theoretical research. It establishes models for predicting the internal relative humidity and autogenous shrinkage of internally cured concrete at early age; reveals the variation law and mechanism of early-age tensile creep of internally cured concrete; and explores the variation law and mechanism of early-age cracking resistance of internally cured concrete under continuous restrained condition or uniaxial restrained condition. It is designed as a reference work for professionals or practitioners and a textbook for undergraduates or postgraduates. As such, this book provides valuable knowledge, useful methods, and practical experience that can be considered in the field of concrete cracking control.

All concrete ingredients (cementing materials, water, aggregates, admixtures, and fibers) are reviewed for their optimal use in designing and proportioning concrete mixtures. Applicable ASTM, AASHTO, and ACI standards are referred to extensively. The use of concrete from design to batching, mixing, transporting, placing, consolidating, finishing, and curing is addressed. Concrete sustainability, along with special concretes, including high-performance concretes, are also reviewed.
