The first chapter on concrete science describes the essential concepts so that information presented in subsequent chapters can be easily followed. The chapter deals with the formation of cement, its hydration behavior, physicochemical processes related to the cement paste, and several important properties of concrete and durability aspects.
Chapter 2 deals with the description of a number of specialized techniques used in conjunction with petrography for the evaluation and analysis of aggregates of concrete.
Chemical analysis methods have been applied extensively to analyze the components of concrete, chemical and mineral admixtures, raw materials for making cement and also to estimate cement contents. Modern analytical tools enable much faster analysis than the wet chemical methods.
In Chapter 3, chemical analysis techniques reviewed include atomic absorption, x-ray emission and plasma spectroscopy. The chapter also contains information on chemical (wet) methods of analysis.
Thermal analysis techniques based on the determination of physical, chemical, and mechanical changes in a material as a function of temperature, have been routinely used in concrete science and technology. Identification, estimation of compounds, kinetics of reactions, mechanisms of the action of admixtures, synthesis of compounds, quality control and causes leading to the deterioration of cementitious materials are investigated by these techniques. Various types of thermal techniques and their applications and limitations are included in Chapter 4.
Although comparatively recent, IR spectroscopy is gaining importance, especially with the development of user-friendly equipment as described in the fifth chapter. This technique has been applied for identification of new products and characterization of raw materials, hydrated materials, and deteriorated products. Discussion on Raman spectroscopy, a complementary technique to IR, also forms a part of this chapter.
Nuclear Magnetic Resonance spectroscopy (NMR) is a effective tool to probe atomic scale structure and dynamic behavior of cementing materials. The application of NMR for determining the pore structure and transport properties of cement and concrete via relaxation and imaging methods and its application to anhydrous cement and hydrated cement phases form some of the contents of Chapter 6.
Scanning Electron Microscopy and its adjunct, microanalytical unit, known as Energy Dispersive X-ray Analyzer, have been accepted as important investigative techniques in concrete technology.
Chapter 7 comprises discussion on the microstructure of hydrated cement paste, C-S-H phase, calcium hydroxide, aluminate hydrate phases, paste-aggregate interface, admixtures, slags, and fly ashes. Also included are studies on the correlation of microstructure with durability.
The eighth chapter on the application of x-ray diffraction focuses on some of the fundamental aspects of the technique, the hardware and software developments, and its applications to cement and concrete.
An understanding of the Theology of fresh cement paste and concrete is essential for following the behavior of concrete in the fresh state. Additions and admixtures in concrete alter its Theological behavior.
Chapter 9 deals with Theological techniques and their application to fresh cement paste and concrete.
Dimensional changes occur in cement paste and concrete due to physical, chemical, and electrochemical processes. A discussion of energetics of surface adsorption and volume changes forms the scope of Chapter 10. Relevance of length changes to concrete deterioration is also highlighted in this chapter.
The use of miniature specimens in cement science investigations has proven to be very valuable because it assures a greater homogeneity of the sample and increased sensitivity to the dimensional changes resulting from physical and chemical processes.
Chapter 11 provides results on compacted powder used as a model system and includes discussion on creep and shrinkage, volume stability, workability, and surface chemical changes.
Corrosion of reinforced concrete is a major destructive process. Many electrochemical techniques have been developed to study corrosion.
Chapter 12 presents a comprehensive treatment of the principles of corrosion, factors responsible for corrosion, and corrosion assessment techniques relevant to concrete.
Surface area has an important influence on the rate of reaction of cement to water and other chemicals. Many physical and mechanical characteristics of cement and concrete are modified by changes in the surface area.
In Chapter 13, the techniques that are used for measuring surface area are given with respect to their application to systems such as raw materials for cement, hydrated cement, concrete mix, and also to durability studies.
The pore structure of hydrated cement systems influences significantly the physico-mechanical and chemical behavior of concrete. Several experimental techniques have been employed to evaluate the microstructure of the cement paste.
Chapter 14 presents a description of six techniques that have been developed for the determination of pore structure. The relationship between pore structure and strength/permeability is also included.
The application of silica polymerization analysis for an understanding of the hydration process and structure of calcium silicate hydrates is detailed in Chapter 15. Three major techniques used for polymerization studies are described.
In concrete, the physical structure and the state of water in the matrix influences the permeation process.
In Chapter 16, test methods that are employed to measure various transport characteristics of concrete are evaluated. The applicability and limitations of these techniques is also reviewed.
Inspection and testing of placed concrete may be carried out by nondestructive testing methods. Sonic and pulse velocity techniques are commonly used. Nondestructive methods are also applied to estimate strength, surface hardness, pullout strength, etc. Details of various nondestructive techniques and their applications are included in Chapter 17.
There is evidence of a significant impact of computer and information technologies on concrete science and technology. General development of these technologies in recent years is reviewed in Chapter 18. The treatment includes computer models, databases, artificial knowledge-based and computer-integrated systems.
In Chapter 19, entitled "Image Analysis," steps needed to identify reactions of interest and extract quantitative information from digital images are reviewed. In image analysis, multiple images are acquired and analyzed. The principle steps required for image analysis of cementitious materials are described in this chapter.
Some of the more commonly used techniques in concrete studies are presented in Chapters 2 to 19. There has been continued interest in developing new techniques for the investigation of cement and concrete.
Chapter 20 comprises the description and application of fourteen of these specialized techniques. They include such techniques as Auger Electron Microscopy, Chromatography, Mass Spectrometry, X-Ray Absorption Fine Structure Analysis, Synchrotron Orbital Radiation Analysis, Mossbauer Spectrometry, Radio Tracer Technique, and Photoacoustic Spectroscopy.
Although every attempt has been made to cover the important investigative techniques used in concrete technology, it is quite possible that some information has been excluded or is missing. In addition, some duplication of information occurs in some chapters. This was intentional because some specific chapters may only be of interest to specialized groups, and they provide enough self-contained information so that gleaning through other chapters will not be needed.
This comprehensive handbook should serve as a reference material to concrete technologists, materials scientists, analytical chemists, engineers, architects, researchers, manufacturers of cement and concrete, standards writing bodies, and users of concrete.

NASA TECHNICAL HANDBOOK-DYNAMIC ENVIRONMENTAL CRITERIA
This handbook is approved for use by NASA Headquarters and all field centers and is intended to provide a common framework for consistent practices across NASA programs. A concerted effort is underway within the NASA engineering community, under the cognizance of the NASA Office of the Chief Engineer, to promote more consistent practices across the NASA centers in the areas of dynamics and structures design and test criteria for spacecraft and payloads. This effort has resulted in NASA standards in the fields of structural design and test factors of safety, loads analyses, vibroacoustic test criteria, and pyroshock test criteria. A parallel effort, also funded by the Office of the Chief Engineer, was undertaken by the Jet Propulsion Laboratory and its contractors to summarize and assess mission dynamic environments, state-of-the-art procedures for predicting the dynamic excitations or loads induced by those environments and the structural responses to those excitations, and for establishing dynamics criteria with appropriate margins for the design and testing of a spacecraft and its components, along with the equipment and procedures used for testing. Contributions were made to this handbook by many members of the aerospace dynamics community; those contributions are gratefully acknowledged.
