- 1 online resource
Summary
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.

Summary
In this report, we establish a numerical model for concrete exposed to irradiation to address these three critical points. The model accounts for creep in the cement paste and its coupling with damage, temperature and relative humidity. The shift in failure mode with the loading rate is also properly represented. The numerical model for creep has been validated and calibrated against different experiments in the literature [Wittmann, 1970, Le Roy, 1995]. Results from a simplified model are shown to showcase the ability of numerical homogenization to simulate irradiation effects in concrete. In future works, the complete model will be applied to the analysis of the irradiation experiments of Elleuch et al. [1972] and Kelly et al. [1969]. This requires a careful examination of the experimental environmental conditions as in both cases certain critical information are missing, including the relative humidity history. A sensitivity analysis will be conducted to provide lower and upper bounds of the concrete expansion under irradiation, and check if the scatter in the simulated results matches the one found in experiments. The numerical and experimental results will be compared in terms of expansion and loss of mechanical stiffness and strength. Both effects should be captured accordingly by the model to validate it. Once the model has been validated on these two experiments, it can be applied to simulate concrete from nuclear power plants. To do so, the materials used in these concrete must be as well characterized as possible. The main parameters required are the mechanical properties of each constituent in the concrete (aggregates, cement paste), namely the elastic modulus, the creep properties, the tensile and compressive strength, the thermal expansion coefficient, and the drying shrinkage. These can be either measured experimentally, estimated from the initial composition in the case of cement paste, or back-calculated from mechanical tests on concrete. If some are unknown, a sensitivity analysis must be carried out to provide lower and upper bounds of the material behaviour. Finally, the model can be used as a basis to formulate a macroscopic material model for concrete subject to irradiation, which later can be used in structural analyses to estimate the structural impact of irradiation on nuclear power plants.

Summary
This document was developed to assist practicing engineers in the design of Composite Special Moment Frame (C-SMF) systems utilizing reinforced concrete columns and steel beams (known as Composite RCS frames). These systems utilize the intrinsic advantages of each material which are optimized in resisting the applied loads.
Seismic design requirements for C-SMF systems are included in ASCE 7 (2010) and AISC 341 (2010). These system-level requirements are supported by research and other documents on the design and detailing of beam-column connections between the steel beams and concrete (or encased composite) columns. In 1994, the ASCE Task Committee on Design Criteria for Composite Structures in Steel and Concrete issued guidelines for the Design of Joints between Steel Beams and Reinforced Concrete Columns in 1994 (ASCE 1994). Based on research at the time, it was recommended to limit the use of Composite RCS systems to regions of low seismicity. Since then, further research has been performed which has demonstrated that Composite RCS systems can be designed to have reliable ductile performance, making them an attractive design alternative for high seismic areas. Based on this research, a draft Pre-Standard for the Design of Moment Connections between Steel Beams and Concrete Columns (ASCE 2015 draft) has been prepared as an update to the 1994 ASCE connection design guidelines. This draft is utilized for the design studies presented herein.

Summary
After an oil, gas, or geothermal production well has been drilled, the well must be stabilized with a casing (sections of steel pipe that are joined together) in order to prevent the walls of the well from collapsing. The gap between the casing and the walls of the well is filled with cement, which locks the casing into place. The casing and cementing of geothermal wells is complicated by the harsh conditions of high temperature, high pressure, and a chemical environment (brines with high concentrations of carbon dioxide and sulfuric acid) that degrades conventional Portland cement. During the 1990s and early 2000s, the U.S. Department of Energy’s Geothermal Technologies Office (GTO) provided support for the development of fly-ash-modified calcium aluminate phosphate (CaP) cement, which offers improved resistance to degradation compared with conventional cement. However, the use of CaP cements involves some operational constraints that can increase the cost and complexity of well cementing. In some cases, CaP cements are incompatible with chemical additives that are commonly used to adjust cement setting time. Care must also be taken to ensure that CaP cements do not become contaminated with leftover conventional cement in pumping equipment used in conventional well cementing. With assistance from GTO, Trabits Group, LLC has developed a zeolite-containing cement that performs well in harsh geothermal conditions (thermal stability at temperatures of up to 300°C and resistance to carbonation) and is easy to use (can be easily adjusted with additives and eliminates the need to “sterilize” pumping equipment as with CaP cements). This combination of properties reduces the complexity/cost of well cementing, which will help enable the widespread development of geothermal energy in the United States.

Summary
This book provides an updated state-of-the-art review on new developments in alkali-activation. The main binder of concrete, Portland cement, represents almost 80% of the total CO2 emissions of concrete which are about 6 to 7% of the Planet's total CO2 emissions. This is particularly serious in the current context of climate change and it could get even worse because the demand for Portland cement is expected to increase by almost 200% by 2050 from 2010 levels, reaching 6000 million tons/year. Alkali-activated binders represent an alternative to Portland cement having higher durability and a lower CO2 footprint. * Reviews the chemistry, mix design, manufacture and properties of alkali-activated cement-based concrete binders* Considers performance in adverse environmental conditions.* Offers equal emphasis on the science behind the technology and its use in civil engineering.

This book provides an updated state-of-the-art review on new developments in alkali-activation. The main binder of concrete, Portland cement, represents almost 80% of the total CO2 emissions of concrete which are about 6 to 7% of the Planet's total CO2 emissions. This is particularly serious in the current context of climate change and it could get even worse because the demand for Portland cement is expected to increase by almost 200% by 2050 from 2010 levels, reaching 6000 million tons/year. Alkali-activated binders represent an alternative to Portland cement having higher durability and a lower CO2 footprint. * Reviews the chemistry, mix design, manufacture and properties of alkali-activated cement-based concrete binders* Considers performance in adverse environmental conditions.* Offers equal emphasis on the science behind the technology and its use in civil engineering.
