America's portland cement industry began in the Lehigh Valley. The rich deposit of limestone known as the Jacksonburg Formation arcs through the valley from Berks County, Pennsylvania, to Warren County, New Jersey, and today it still provides the raw material for the Lehigh district's famous high-quality portland cement. Cement from the Lehigh Valley built America's skyscrapers, dams, and highways. The Lehigh Valley Cement Industry documents not only the quarries and cement mills but also the dozens of companies that sprang up to supply and support the industry. The photographs also tell the stories of the people who formed the cement communities—the entrepreneurs, executives, engineers, and immigrants whose legacies live on in the five multinational companies still making cement in the valley.

Cement is the basis of the building and construction industry and of fundamental importance for many civil engineering applications. As such, the cement industry is one of the key industries worldwide necessary for the current and future sustainable development of society. Despite its undisputed importance, the cement industry is one of those industrial branches predominately responsible for high energy consumption and excessive generation of large amounts of carbon dioxide and other contaminants that significantly endanger human health and the environment and contributes to global warming.In this context, nanomaterials, polymeric materials, and natural additives are being used for cement enhancement in various applications. This book examines these novel materials and their optimization, characterization, and sustainable application in the building industry and for stabilizing hazardous waste.
Cement production is known to be a polluting and energy-intensive industry. Cement plants account for 5 percent of global emissions of carbon dioxide and one of the main causes of global warming. However, cement it is literally the glue of progress. Designing Green Cement Plants provides the tools and techniques for designing new large cement plants that would promote sustainable growth, preserve natural resources to the maximum possible extent and make least possible additions to the Greenhouse Gases that cause global warming. Brief and but authoritative, this title embraces new technologies and methods such as Carbon Capture and Sequestration, as well as methods for harnessing renewable energy sources such as wind and solar. The author also discusses the efficient use of energy and materials through the use recycling. In addition, this book also examines thepossibilities of developing green cement substitutes such as Calera, Caliix, Novacem, Aether and Geopolymer cements. - Includes the tools and methods for reducing the emissions of greenhouse Gases - Explores technologies such as: carbon capture and storage and substitute cements - Provides essential data to determining the unique factors involved in designing large new green cement plants - Includes interactive excel spreadsheets - Methods for preforming a cost benefits analysis for the production of green cements as opposed to conventional OPC
• New York Times bestseller • The 100 most substantive solutions to reverse global warming, based on meticulous research by leading scientists and policymakers around the world “At this point in time, the Drawdown book is exactly what is needed; a credible, conservative solution-by-solution narrative that we can do it. Reading it is an effective inoculation against the widespread perception of doom that humanity cannot and will not solve the climate crisis. Reported by-effects include increased determination and a sense of grounded hope.” —Per Espen Stoknes, Author, What We Think About When We Try Not To Think About Global Warming “There’s been no real way for ordinary people to get an understanding of what they can do and what impact it can have. There remains no single, comprehensive, reliable compendium of carbon-reduction solutions across sectors. At least until now. . . . The public is hungry for this kind of practical wisdom.” —David Roberts, Vox “This is the ideal environmental sciences textbook—only it is too interesting and inspiring to be called a textbook.” —Peter Kareiva, Director of the Institute of the Environment and Sustainability, UCLA In the face of widespread fear and apathy, an international coalition of researchers, professionals, and scientists have come together to offer a set of realistic and bold solutions to climate change. One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. If deployed collectively on a global scale over the next thirty years, they represent a credible path forward, not just to slow the earth’s warming but to reach drawdown, that point in time when greenhouse gases in the atmosphere peak and begin to decline. These measures promise cascading benefits to human health, security, prosperity, and well-being—giving us every reason to see this planetary crisis as an opportunity to create a just and livable world.
The first Edition of the book came out in 2008. It covered all aspects of Designing Cement Plants- mainly Dry Process Cement Plants with 6 stage Preheaters and Calciners, Vertical Mills, Electro Static Precipitators and various auxiliary machineries as were prevalent then. The base size for various workouts was 3000 TPD as was prevalent then. It has begun to dawn on Cement Industry that it was responsible for emitting 5 % of the most common greenhouse gas - CO2. Cement Industry and Cement Plant and Process Designers began to apply their minds to make - GREEN Cement. - which emitted greenhouse gas in much less quantities by making blended cements, using alternate fuels and by recovering waste heat. Mr. Deolalkar's book 'Designing Green Cement Plants' dealing with these aspects came out in 2013. Cement Industry was also growing in size simultaneously and the base size of 3000 TPD has been replaced by cement plants of + 10000 TPD or + 3mtpa capacity cement plants, requiring sea changes in machinery used therein. This Second Edition of the Handbook includes all aspects of the basic concepts dealt with in the Handbook but also includes aspects of making green cement. The base capacity is now 10000 TPD. Therefore it has been named Handbook for Designing Green Cement Plants. This book will also be found to be very useful to the Cement Industry. Author's two books mentioned above have been included in the top 20 books related to Cement Industry in the World.Contents: Section - 1 Basics Section - 2 Machinery Used in Making cement Section - 3 Technoeconomic Feasibility Studies Section - 4 Civil Design and Construction Section - 5 Electricals and Instrumentation Section - 6 Layouts and Detailed Engineering Section - 7 Selecting and Ordering Machinery Section - 8 Sustainable Development Section - 9 Web Pages Section 10 - Sources Section 11 - Recommended Reading
