CONCRETE SIDNEY MINDESS PDF

For those familiar with the first edition, very little has been removed, while the chapters on cements, aggregates, chemical admixtures, concrete construction practices, and durability have undergone major revision. In addition, the text now contains new, separate chapters on - mineral admixtures - high-strength concrete - cement-polymer composites - fiber-reinforced concrete As in the first edition, the authors present a unified view of concrete behavior based on basic principles. The material on workability of concrete is prefaced by a general discussion of the principle of rheology; mechanical properties are discussed from the point of view of concrete as a multiphase material; and the underlying chemistry of hydration and microstructure of hardened cement paste are emphasized. The result is a cohesive presentation of practical applications supported by detailed background information, which serves both the undergraduate and the practicing professional engineer.

As is the case with any material, its successful use depends upon an intelligent application of its properties in design and the supply of a uniform, high quality product. Concrete is unique among major construction materials in that it is generally designed specifically for a particular project using locally available materials.

Therefore, the project engineer has full control and responsibility over the final material used in construction. If concrete is not properly designed for the service conditions and is not properly handled and cured, it will result in substandard performance. For example, when concrete bridge decks and pavements commonly require extensive maintenance years after placement, it is a clear indication that the material is not being used to its full potential.

It is thus essential that engineers acquire a thorough understanding of the material properties of concretes and the procedures that are essential to providing a material of the required quality and durability. In the past, concrete technology has been taught largely as an empirical science. However, there is a body of chemical and physical principles underlying the behavior of concrete that are now relatively well understood. As with the first edition, it is the aim of this text to present a unified view of concrete behavior in light of these principles, rather than as a series of more or less unrelated facts.

For instance, the material on the workability of concrete is prefaced by a general discussion of the principles of rheology; mechanical properties are discussed from the point of view of concrete as a composite or multiphase material; and the underlying chemistry of hydration and microstructure of the hardened cement paste are emphasized.

This book is designed primarily for use at the undergraduate level, but it should also serve as a guide for the professional engineer who did not take a formal course on concrete in college. It includes the most up-to-date information available on new concrete materials, and considerable attention is given to the role of specifications for concrete and concrete materials and the use of test methods for determining concrete properties.

To provide a comprehensive treatment, more material is included than can be covered in detail in one semester. Therefore, the instructor will have to choose to omit certain topics. Chapter 4 contains more chemistry than might be considered desirable for an undergraduate course and could be treated in less detail by concentrating only on the reactions of the principal cement compounds.

Also, those sections in Chapter 16 dealing with mechanisms of shrinkage, strain-rate dependence, and creep could be omitted if desired, although they contribute to a more basic understanding of the material.

The book is divided into three main parts: The properties of the constituent materials: cements, hardened cement paste, aggregates, water and admixtures. Proportioning of concrete mixes and construction practices: mixing, transporting, placing and consolidating, and curing. The properties of hardened concrete: strength and fracture, fatigue, Creep and drying shrinkage, and durability. In view of the fact that SI units are in use in Canada, and are being adopted in the United States, we have chosen to use SI units as the primary system.

Conversion to the English system is given throughout the text, as appropriate. Numerical problems have been given using both sets of units. In preparing the text, reference was made to the most up-to-date editions of the standards and recommendations available.

These are subject to frequent revision and the reader should therefore refer to the most recent editions, which may differ in some details from those referred to in the text.

A selected bibliography is provided with each chapter as a guide to further reading and to provide a point of entry to the original scientific literature. Some exercises are given at the end of each chapter.

Selection of these has been difficult since the subject does not lend itself to numerical problems, but they have been chosen to emphasize the important aspects of each chapter. It has been 22 years since publication of the first edition. Much progress has been made in many areas of concrete technology, necessitating some modification in coverage. For those familiar with the first edition, very little has been removed.

The text now contains new, separate chapters on mineral admixtures, cement-polymer composites, and fiber reinforced concrete, subjects that had been included as part of other chapters in the first edition. The chapters on cements, aggregates, chemical admixtures, concrete construction practices, and durability have undergone major revisions and the information on architectural concrete has been moved into Chapter 20 on Concrete for Special Applications.

Several chapters that addressed the response of concrete to stress have been consolidated into a single, thoroughly revised, chapter.

And, the text now includes an all new chapter on high-strength concrete.
