Standard X-Ray Diffraction Powder Patterns
NBS MONOGRAPH 25 — SECTION 1 Standard X-ray Diffraction U.S. DEPARTMENT OF COMMERCE NATIONAL BUREAU OF STANDARDS THE NATIONAL BUREAU OF STANDARDS Functions and Activities The functions of the National Bureau of Standards are set forth in the Act of Congress, March 3, 1901, as amended by Congress in Public Law 619, 1950. These include the development and maintenance of the national standards of measurement and the provision of means and methods for making measurements consistent with these standards; the determination of physical constants and properties of materials; the development of methods and instruments for testing materials, devices, and structures; advisory services to government agencies on scien- tific and technical problems; invention and development of devices to serve special needs of the Government; and the development of standard practices, codes, and specifications. The work includes basic and applied research, development, engineering, instrumentation, testing, evaluation, calibration services, and various consultation and information services. Research projects are also performed for other government agencies when the work relates to and supplements the basic program of the Bureau or when the Bureau's unique competence is required. The scope of activities is suggested by the listing of divisions and sections on the inside of the back cover. Publications The results of the Bureau's research are published either in the Bureau's own series of publications or in the journals of professional and scientific societies. The Bureau itself publishes three periodicals available from the Government Printing Office: The Journal of Research, published in four separate sections, presents complete scientific and technical papers; the Technical News Bulletin presents summary and preliminary reports on work in progress; and Basic Radio Propagation Predictions provides data for determining the best frequencies to use for radio communications throughout the world. -
Delayed Ettringite Formation
Ettringite Formation and the Performance of Concrete In the mid-1990’s, several cases of premature deterioration of concrete pavements and precast members gained notoriety because of uncertainty over the cause of their distress. Because of the unexplained and complex nature of several of these cases, considerable debate and controversy have arisen in the research and consulting community. To a great extent, this has led to a misperception that the problems are more prevalent than actual case studies would indicate. However, irrespective of the fact that cases of premature deterioration are limited, it is essential to address those that have occurred and provide practical, technically sound solutions so that users can confidently specify concrete in their structures. Central to the debate has been the effect of a compound known as ettringite. The objectives of this paper are: Fig. 1. Portland cements are manufactured by a process that combines sources of lime (such as limestone), silica and • to define ettringite and its form and presence in concrete, alumina (such as clay), and iron oxide (such as iron ore). Appropriately proportioned mixtures of these raw materials • to respond to questions about the observed problems and the are finely ground and then heated in a rotary kiln at high various deterioration mechanisms that have been proposed, and temperatures, about 1450 °C (2640 °F), to form cement compounds. The product of this process is called clinker • to provide some recommendations on designing for durable (nodules at right in above photo). After cooling, the clinker is concrete. interground with about 5% of one or more of the forms of Because many of the questions raised relate to cement character- calcium sulfate (gypsum shown at left in photo) to form portland cement. -
Calcium Sulfate Precipitation Throughout Its Phase Diagram
Chapter 12 Calcium Sulfate Precipitation Throughout Its Phase Diagram Alexander E.S. Van Driessche, Tomasz M. Stawski, Liane G. Benning, and Matthias Kellermeier 12.1 Introduction Over the past decade, significant progress has been made in our understanding of crystallization phenomena. In particular, a number of precursor and intermediate species, both solutes and solids, and either stable or metastable (or even unstable), have been identified. Their existence extends the simplified picture of classical nucleation and growth theories toward much more complex pathways. These newly found species include various solute clusters, liquid-like phases, amorphous particles, and metastable (often nanosized) crystalline polymorphs, all of which may exist for different periods and may convert into one another depending on the chosen conditions (see, for instance, De Yoreo et al. 2017, Chap. 1; Wolf and Gower 2017, Chap. 3; Rodriguez-Blanco et al. 2017, Chap. 5; Birkedal 2017, Chap. 10; Reichel and Faivre 2017, Chap. 14, and references therein).

The morphology of the precipitated crystals evolves from a needle-like shape to a platelet-like shape when temperature is increased from 25 to 90°C; when the initial concentration of the acid is increased from 15 to 30 wt%; or when the inlet flow of the suspension of calcite is decreased from 20 down to 5ml/min. -
