DISPONIBILIDADE IMEDIATA

 In conditions of increasing demand for natural raw materials, the problem of integrated use of all extracted raw materials and environmental protection is of paramount importance and is becoming more acute every year. In the coal-industrial regions of any country, huge reserves of mine rocks and ash and slag waste are concentrated in dumps. Significant amounts of money are spent on storing waste, and areas of farmland are taken away. Waste from the fuel and energy complex poses a serious threat to the environment of our planet. This problem needs to be solved. Scientists all over the world are conducting research in this direction. The use of burnt mine rocks and ash and slag waste in the construction materials industry is a strategic way to expand the raw material base of this industry and solve environmental problems to improve the state of the environment in areas where thermal power plants operate and in regions with a developed coal industry. This book presents the results of many years of research on the use of burnt mine rocks and ash and slag waste in the technology of building materials. The results of the use of technogenic raw materials in the technology of building materials of a wide range are presented. The positive effect of this raw material on the physical and mechanical properties and quality of the resulting product has been confirmed. This is confirmed by the practice of using products using technogenic raw materials-burnt rocks from mine dumps of ash and slag materials. Products with high consumer properties at a relatively low cost can win the competition. The use of coal mining and combustion waste-mine rocks and ash and slag waste-will help improve product quality and reduce costs for the production of building materials.

278,25€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Refractory materials are used in several industries involving very aggressive environments, thus the number of chemical, thermal and physical properties required for a refractory material are high and diverse. In Refractory Materials: Characteristics, Properties and Uses, the authors suggest that the determination of the mineralogical phase’s amounts is an essential parameter for the design of new refractories matrix to have command over the desired properties and quality of the final product. The subsequent chapter may serve as a guide to the composition- and microstructure-based interpretation of experimental findings in refractory materials. Based on the concepts and refractory materials data provided in this book, taking into account the general issues concerning strength measurements, the reader should be able to realistically assess even such complex quantities as thermal shock resistance parameters. Next, a systematic joint study of the temperature dependences of the isobaric molar heat capacity CP(T) and the volume coefficient of thermal expansion (T) of polyatomic solids was carried out on the example of refractory oxide ceramics: periclase, MgO, and corundum, Al2O3. Both ceramics have the widest practical applications and are considered as reference substances, which justifies their choice for research. In the closing chapter, the B-model is applied to a joint study of temperature dependences of the principal thermodynamic functions of the selected refractory oxide ceramics, namely, periclase, MgO, and corundum, Al2O3. Primarily, the isobaric molar heat capacity CP(T), the volume coefficient of thermal expansion (T), and their correlation, (CP), were investigated between T = 0 and the melting point Tm. Under the B-model control, mutually consistent calorimetric (change in the molar enthalpy, the molar entropy, the reduced thermodynamic potential) and dilatometric (the molar volume, the volume coefficient of thermal expansion) data were obtained and tabulated in the entire solid state range of the ceramics.

304,75€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The concept of a circular economy in the construction sector captures global material flow through product design, inverse logistics, innovation and collaborations. The circulation of the economy takes into consideration global population influence, which affects the economy through a variety of construction product flows in particular. The increase in consumers means increasing product and services which participate in different waste streams. The emerging sustainable development in the construction industry requires the recycling of waste materials to reduce the negative environmental impact of construction activities. Accumulation and management of construction wastes is also becoming a major environmental and economical concern in many developing countries. Huge volumes of waste generated end up piled on landfill sites or illegally dumped, posing serious health and ecological problems. In the construction industry, recycling of waste concrete, masonry, cement, gypsum, to mention but a few, has become an important aspect due to the continued increase of construction wastes and depletion of natural aggregates. Why not establish a business system that is specifically designed to do much more value addition to the construction wastes and develop products which are not only in demand locally but internationally, to encourage exports for maximum financial gain. This book aims to analyze the current business model in the construction sector and the current legislation concerning waste management. It also highlights efforts required in order to refine the recycling methods in favor of a circular economy in the constuction industry. In support of a transition to a low carbon economy, different types of materials which can be produced from the construction wastes are indicated including processes which are used to obtain the final products. The market demand including penetration of the resulting products are given extensively. Policies and regulations to govern these undertakings are highlighted also. The municipalities will learn to redirect the local construction industries on how to avoid dumping at landfill sites as the space has currently become an issue. Researchers globally will learn how to go up through the Technology Readiness Levels (TRL) from basic research through prototype development and finally up to commercialization in projects related to the construction.
