Temperature Development in Early Age Concrete Elements : Fundamentals, Prediction and Control

This shows how to predict time-temperature profiles in large concrete elements, resulting from the heat generated by the hydration of cement during the early stages of concrete construction. It sets out the evolution and flow of heat with finite-difference modelling, together with a number of case-studies.

The focus of this book is to provide guidance on the prediction of time-temperature profiles in large concrete elements during the early stages of construction, with a view to minimising the likely damage that may occur to the concrete as a result of elevated temperatures caused by the heat of hydration of the cementitious materials. Early-age elevated temperatures in concrete elements create the potential for cracking of the structure as well as compromising the strength and durability of the concrete. The book provides details on the characteristics of cementitious materials and their effects on the rate of heat evolution as well as the effects of elevated curing temperatures on the physical, mechanical and durability properties of concrete. The book also considers the effectiveness of materials selection and construction methodologies for early-age concrete temperature management and control. Several case studies are presented to illustrate the important aspects in the design and construction of temperature-sensitive concrete structures. This book is primarily aimed at practicing design and construction engineers who are concerned with thermal effects and stresses in large concrete elements. It is also aimed at researchers and postgraduate students who may consider aspects of this wonderfully complex matter of heat transfer and temperature prediction in large concrete structures, as sufficiently interesting to warrant further research and investigation.
