Book excerpt: Excerpt from Properties of Portland Cement Having a High Magnesia Content Further investigations on this subject are needed because Of the failures of mortars and concretes which have been attributed to such cements. The specifications under which cements are usually bought do not demand the making Of test pieces of the material to be tested at late periods'; but high-magnesia cements are gener ally conceded to be able to pass all the requirements demanded of the short-time tests. However, with the hydration Of the com pounds present in such cements it is claimed by some that there is a Slow but gradual increase in volume, which is manifested at late periods by low results for the strength of test pieces and finally by complete disintegration of the materialf While such cements may be satisfactory at early periods and pass the usual specifica tions, there is a strong belief in the minds of many that ultimately they will fail. As this phenomenon Of the large increase in volume accompanying the slow hydration of the constituents in high-magnesia cements can be Observed apparently only at late periods, it is essential to Obtain some. Definite information in regard to this property, if it exists. It might be possible with this infor mation to make definite predictions as to the ultimate behavior of such cements, even though short-time tests should Show them to be satisfactory.

Download or read book Magnesia Cements written by Mark Shand and published by Newnes. This book was released on 2020-05-30 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an urgent need for innovative, cost-effective, and sustainable approaches to reduce the tremendous environmental impact of conventional cement and cement-based technologies. Consuming a significantly lower quantity of natural resources than conventional cements, with the added ability to effectively sequestering carbon, magnesia cements offer great potential in this area. Magnesia Cements: From Formulation to Application explores the latest developments in this exciting area, reviewing the unique properties offered by these cements, including superior strength, fire resistance, and exceptional ability to bond to a wide range of aggregates, and highlighting their potential role in making cement production and usage more sustainable. Providing detailed analysis of the chemistry, properties, manufacture, and both traditional and novel applications, Magnesia Cements: From Formulation to Application is ideally suited for materials scientists, cement chemists, ceramicists, and engineers involved with the design, development, application and impact assessment of magnesia cements across both academia and industry. Provides formulary information research into more environmentally friendly cement systems Discusses chemical phase analysis and the impact of formulation Applies analysis and history of global uses to provide support for future environmentally stable industrial, building, and non-building applications

Download or read book High Magnesia Portland Cements Study of Cement Prepared with Commercial Raw Materials written by S. S. Rehsi and published by . This book was released on 1969 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: High magnesia Portland cements prepared in the laboratory from low-grade Indian limestones and containing as high as 15 per cent MgO can be made volume-stable by mixing with them suitable quantities of an active silicate material such as pulverised fuel ash. These mixtures pass the ASTM autoclave expansion test and also posess adequate strengths to satisfy the Indian Standard specifications. Pulverised fuel ashes from power stations at Delhi, Bokaro and Durgapur as well as powdered burnt clays were found to be very suitable as additives. Granulated blastfurnace slag from the Rourkela steel plant was found to be unsatisfactory for the purpose of controlling the volume expansion of high magnesia cements. The results correspond very well with those of a previous study in which the stabilisation of cements produced from reagent grade chemicals was investigated. (Author).

Download or read book Mechanism of Stabilization of High magnesia Portland Cements by Reactive Silica Under Autoclave Conditions written by Amal J. Majumdar and published by . This book was released on 1969 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Factors which play important roles in the mechanism of stabilization of high-magnesia Portland cements by active silicate materials under autoclave conditions were considered. Among these, reduction in the rate of hydration of uncombined MgO, formation of a magnesium silicate hydrate similar to the natural mineral deweylite and development of substantial strength in autoclaved products are thought to be the principal factors which control the volume expansion of these cements. It is proposed that strength development in these materials is consequent upon the formation of large amounts of the well crystallized 11 A tobermorite phase. The extra strength generated in autoclaved mixtures of cement when they incorporate active silica may be sufficient to contain the expansive forces generated by the hydration of periclase into brucite. Much Mg(OH)2, very little Ca(OH)2 and some MgO are present in the final products in addition to tobermorite. Some information on the microstructure of the stabilized cement as seen with a scanning electron microscope is given. (Author).
