building materials pdf
The primary purpose of writing this book is to give engineering students up-to-date information on building materials. The book has been prepared after referring to a number of text books, references and standards. S.I. units have been used throughout the text as far as possible. The author has tried to incorporate essential information concerning manufacture/fabrication of the various building materials; the data covering the more important mechanical and physical properties, influences of various factors on these properties; the causes of defects, their prevention and remedies; testing of materials. An attempt has also been made to present to the reader some of the more general uses and applications of the different materials.
The author gratefully acknowledges the considerable encouragement, splendid help and valuable suggestions received form his colleagues. Appreciation and thanks are also due to those students who went through the preliminary and final scripts. Finally thanks are due to my wife Suman and children Swati and Shashank for their tolerance during this trying time. Efforts have been made to keep errors to a minimum. However, they are inevitable. Suggestions are welcomed from all concerned pointing out any oversights.
The second edition of this book deals with properties of building materials and techniques for
their manufacturing. Applications of building materials have been presented with emphasis on engineering and economic approaches for determining the optimum kind of materials, best suited to specific conditions of service in buildings. This edition provides a thorough and practical groundwork for students of civil, architecture and construction technology. The expanded and updated text can also serve as a refresher and reference for practicing civil engineers, architects, contractors, and other workers who must be aware of new building materials and techniques.
The building materials industry is in continual development, the range of products is being expanded, and novel techniques for optimizing production processes are being introduced. The main purpose of the book is to present a basic course of study with a detailed coverage of basic theory and practice of the manufacture of building materials. The present edition embodies material change in the chapters dealing with lime, cement, concrete, and many other minor revisions.Since concrete (Chapter 10) is the most widely and extensively used building material, its production, properties, and testing have been thoroughly revised and discussed in more details and depth.
Chapter 11 on mix design has been introduced to make the used understand better the manufacture and properties of concrete. Standards laid by Bureau of Indian Standards have been followed. Extensive addition in Chapter 20, miscellaneous materials, include elaboration of geotextiles, new types of cements and concretes—their properties and production processes. All this was possible due to the suggestions, and comments received form many individuals and students. I would like to thank all of them. Acknowledgement is also made to New Age Publishers for publishing the second edition.
