Direct Electric Curing of Concrete: Basic Design By I.D. Kafry
The study of cements, aggregates and the other components of concrete, has developed and grown over the years to the point where it has become a science. However, one process remains difficult to define and quantify – and that is curing. Natural curing was common practice but the demands of modern industry led to accelerated curing, whether through the use of chemical or the application of vacuum or heat. This specialist review provides a detailed treatment of the subject, clarifying and quantifying aspects of the subject pertinent to the curing of concrete. The author of this book discusses the underlying basic principles before examining the design procedure, which is complemented with worked examples. All facets of the process are considered, from the electrical installation and calculation of power required, to the economic factors and implementation of a scheme.

The Complete Lab Manual for Electricity By Stephen Herman
The Complete Laboratory Manual for Electricity, 3rd Edition is a valuable tool designed to fit into any basic electrical program that incorporates lab experience. This updated edition will enhance your lab practices and the understanding of electrical concepts. From basic electricity through AC theory, transformers, and motor controls, all aspects of a typical electrical curriculum are explored in a single volume. Each lab features an explanation of the circuit to be connected, with examples of the calculations necessary to complete the exercise and step-by-step procedures for conducting the experiment. Hands-on experiments that acquaint readers with the theory and application of electrical concepts offer valuable experience in constructing a multitude of circuits such as series, parallel, combination, RL series and parallel, RC series and parallel, and RLC series and parallel circuits.
