Carbon Dioxide Sequestration In Cementitious Construction Materials

Carbon Dioxide Sequestration in Cementitious Construction Materials – Second Edition follows on the success of the previous edition and provides an up-to-date review on recent research developments on cementitious construction materials based on carbon dioxide storage. Along with the addition of an entire new section on bio- sequestration. Brand new chapters are included on carbonation methods such as carbon sequestration of cement pastes during pressurized CO2 curing; carbon dioxide sequestration of low-calcium fly ash via direct aqueous carbonation; increasing the efficiency of carbon dioxide sequestration through high temperature carbonation; and carbon sequestration in engineered cementitious composites. There are also several new case studies on sequestration of industrial wastes, which include carbon dioxide sequestration by direct mineralization of fly ash; the effect of direct carbonation routes of basic oxygen furnace slag on strength and hydration of blended cement paste; carbon sequestration of mine waste and utilization as a supplementary cementitious material and carbon dioxide sequestration on masonry blocks based on industrial wastes. This updated edition will be a valuable reference resource for academic researchers, materials scientists and civil engineers, and other construction professionals looking for viable routes for carbon sequestration in building materials. Promotes the importance of CO2? storage in carbonation of construction materials, especially reincorporation of CO2? during fabrication Discusses a wide range of cementitious materials with CO2? storage capabilities Features redesign of cementation mechanisms to utilize CO2? during fabrication Covers biosequestration

This book focuses on an important technology for mineralizing and utilizing CO2 instead of releasing it into the atmosphere. CO2 mineralization and utilization demonstrated in the waste-to-resource supply chain can “reduce carbon dependency, promote resource and energy efficiency, and lessen environmental quality degradation,” thereby reducing environmental risks and increasing economic benefits towards Sustainable Development Goals (SDG). In this book, comprehensive information on CO2 mineralization and utilization via accelerated carbonation technology from theoretical and practical considerations was presented in 20 Chapters. It first introduces the concept of the carbon cycle from the thermodynamic point of view and then discusses principles and applications regarding environmental impact assessment of carbon capture, storage and utilization technologies. After that, it describes the theoretical and practical considerations for “Accelerated Carbonation (Mineralization)” including analytical methods, and systematically presents the carbonation mechanism and modeling (process chemistry, reaction kinetics and mass transfer) and system analysis (design and analysis of experiments, life cycle assessment and cost benefit analysis). It then provides physico-chemical properties of different types of feedstock for CO2 mineralization and then explores the valorization of carbonated products as green materials. Lastly, an integral approach for waste treatment and resource recovery is introduced, and the carbonation system is critically assessed and optimized based on engineering, environmental, and economic (3E) analysis. The book is a valuable resource for readers who take scientific and practical interests in the current and future Accelerated Carbonation Technology for CO2 Mineralization and Utilization.

The principal aim of this book is to provide an overview of the CO2 emission coming from the construction industry and the capability of cement-based materials such as concrete and controlled low strength material (CLSM) for the sequestration of carbon dioxide gas to help reduce global warming. The information and data contained in this book have been selected from a wide variety of sources. An economical, efficient, and viable technology for the sequestration of carbon dioxide in typical concrete, no-fines concrete, CLSM, and other similar cement-based materials, are described in this book. The capability of earning carbon credit by sequestration of CO2 in cement-based materials is also demonstrated. The authors believe that this book should be useful to cement manufacturers, thermal power plants owners, practicing engineers, academicians, environmental regulatory authorities, and the construction industry.

To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.

In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.
