  • 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.

  • 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.

The results of chemical, physical and X-ray studies of these minerals are described, with their mineral associ ations and modes of occurrences. Introduction Mesolite and scolecite are usually classified as common fibrous zeolites, but there has been no report on the occurrence of these zeolites in Japan though the thermal and chemical data of mesolite from Tezuka, Nagano, Japan, was given by Koizumi (1953). However, our routine examinations of fibrous zeolites in the National Science Museum, Tokyo, recently confirmed that mesolite and scolecite are not so rare in Japan as hitherto believed. This paper deals with the 310 Mineralogical Notes on Mesolite and Scolecite from Japan descriptions of scolecite and mesolites from Japan. a) Mesolite from Tezuka, Nishisioda-mura, Chiisagata-gun, Naga no, Japan (coll. by Takaharu Imayoshi). This mineral occurs as fibrous aggregates, sometimes associated with heulandite, in the vein lets (2-3cm wide) in andesitic tuff breccia. The DTA, TGA and chemical analysis of this specimen were provided by Koizumi (1953). b) Mesolite from Oshima, Otsuki City, Yamanashi, Japan (coll. by the writers). This mineral occurs as fibrous aggregates closely associated with stilbite in amygdales (1-2cm) of thoroughly altered olivine basalt.

Currently, however, this Received 12 February 2016 pigment is difficult to find, either in powder or in paint, with sufficient purity and without undesired Accepted 8 November 2016 additives. Furthermore, the traditional methods of producing it are not feasible to use in the studio or Available online xxx laboratory. Therefore, the present work proposes a new method of producing the pigment on a small scale, to be used in the fields of the plastic arts, in restoration of works of art, and in research. The method Keywords: consists of precipitating white lead from aqueous solutions of lead nitrate and sodium carbonate. The White lead procedure is simple, quick, and without unpleasant materials or handling, and the resulting pigment is Restoration of great purity and similar to traditional white lead.
