The quality and testing of materials used in construction are covered by reference to the appropriate ASTM standard specifications. Welding of reinforcement is covered by reference to the appropriate AWS standard. Uses of the Code include adoption by reference in general building codes, and earlier editions have been widely used in this manner. The Code is written in a format that allows such reference without change to its language. Therefore, background details or suggestions for carrying out the requirements or intent of the Code portion cannot be included. The Commentary is provided for this purpose. Some of the considerations of the committee in developing the Code portion are discussed within the Commentary, with emphasis given to the explanation of new or revised provisions. Much of the research data referenced in preparing the Code is cited for the user desiring to study individual questions in greater detail. Other documents that provide suggestions for carrying out the requirements of the Code are also cited.

Sound waves propagate through galactic space, through two-dimensional solids, through biological systems, through normal and dense stars, and through everything that surrounds us; the earth, the sea, and the air. We use sound to locate objects, to identify objects, to understand processes going on in nature, to communicate, and to entertain. The elastic properties of materials determine the velocity of sound in them and tell us about their response to stresses something which is very important when we are trying to construct, manufacture, or create something with any material. The Handbook of Elastic Properties of Materials will provide these characteristics for almost everything whose elastic properties has ever been measured or deduced in a concise and approachable manner. Leading experts will explain the significance of the elastic properties as they relate to intrinsic microscopic behavior, to manufacturing, to construction, or to diagnosis. They will discuss the propagation of sound in newly discovered or created materials, and in common materials which are being investigated with a fresh outlook. The Handbook will provide the reader with the elastic properties of the common and mundane, the novel and unique, the immense and the microscopic, and the exhorbitantly dense and the ephemeral.. You will also find the measurement. And theoretical techniques that have been developed and invented in order to extract these properties from a reluctant nature and recalcitrant systems. Key Features * Solids, liquids and gases covered in one handbook * Articles by experts describing insights developed over long and Illustrious careers * Properties of esoteric substances, such as normal and dense stars, superfluid helium three, fullerness, two dimensional solids, extraterrestial substances, gems and planetary atmospheres * Properties of common materials such as food, wood used for musical instruments, paper, cement, and cork * Modern dynamic elastic properties measurement techniques

Experten aus dem In- und Ausland erläutern in ihren Artikeln die Entwicklung und den Einsatz der Betontechnologie – insbesondere moderner Hochleistungsbetone. Ferner würdigen sie den Beitrag von Professor Harald Budelmann zur Baustoff- und Bauwerksprüfung. Breit diskutiert werden Fragen zur Dauerhaftigkeit und zur Nachhaltigkeit in der Baustoffentwicklung, andere, praxisbezogene Beiträge widmen sich der Zustandserfassung und der Instandsetzung oder auch der Beurteilung der Sicherheit und Leistungsfähigkeit von Bauwerken.
