Opis

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 mean that they are less forgiving than in the past. Therefore, any activity that will help improve hydration and so performance, while reducing the risk of cracking, is becoming more important. Curing Concrete explains exactly why curing is so important and shows you how to best do it. The book covers:

• The fundamentals behind hydration
• How curing affects the properties of concrete, improving its long-term performance
• What curing technologies and techniques you can use for different applications
• How to effectively specify, provide, and measure curing in a project

The author also gives numerous examples of how curing-or a lack of it-has affected concrete performance in real-world situations. These include examples from hot and cold climates, as well as examples related to high-performance concrete, performance parameters, and specifications and testing. Written for construction professionals who want to ensure the quality and longevity of their concrete structures, this book demonstrates that curing is well worth the effort and cost.

Peter C. Taylor was born and educated in Southern Africa, and gained a B.Sc. and Ph.D. from the University of Cape Town. He spent ten years with consultants in Chicago involved in a wide range of consulting and research projects investigating the effects of raw materials on concrete performance, both in the laboratory and in the field, and since 2007 has been employed at the National Concrete Pavement Technology Center at Iowa State University. He also travels throughout the United States teaching practitioners about the latest technologies available to improve pavement reliability and sustainability. Dr. Taylor is the author of more than 50 publications and is an active member of Transportation Research Board (TRB), ASTM International, and American Concrete Institute (ACI) committees.
