The Structural Integrity of Recycled Aggregate Concrete Produced with Fillers and Pozzolans presents a review on the use of by-products, fillers and pozzolanic materials in the development of concrete, with an emphasis on structural integrity. The volume is broken down into key sections, including a review of the types of materials that are used as latent hydraulic supplements, fillers and pozzolans for making recycled aggregate concrete, rheology and hydration phenomenon, the mechanical and microscale nature of concrete, and the impact of fillers and pozzolans on the workability of concrete with case studies. Durability and strength development are also discussed. The final section looks at issues such as performance effect, LCA, environmental impact, sustainability and cost benefit analysis. With detailed case studies throughout, this volume will provide useful information for all stakeholders involved in the built environment, including materials scientists, civil engineers, builders, architects and policymakers. - Identifies several potential by-products, fillers and pozzolans for the development of durable concrete - Acts as a guidebook for constructors and researchers working in the broad field of material science, engineering and in-situ application - Presents the durability properties of concrete made of by-products, fillers and pozzolans
Design of High-performance Pre-engineered Steel Concrete Composite Beams for Sustainable Construction
This accessible and practical shortform book details the properties and advantages of high-performance pre-engineered steel-concrete composite beams (HPCBs) for improving the sustainability of construction techniques. It also explains the analysis methods for testing HPCB systems. The authors describe a new HPCB system that has been developed to reduce the input of raw materials and embodied CO2 commonly associated with heavily loaded and long-spanned industrial buildings (which predominately comprise reinforced concrete) and improve the sustainability of the construction process. They provide several resources throughout to facilitate adoption by professionals. Design equations derived from Eurocode 4 approach for ultimate limit state and serviceability limit state and worked examples are included throughout. The authors discuss the feasibility for both materials and the full-scale beams and CO2 reduction methods, including use of recycled concrete aggregate, ground granulated blast-furnace and silica fume to replace natural coarse aggregates and Ordinary Portland Cement. Guidance for testing HPCBs—including setup, test procedure and data collection and interpretation—is also given. The authors also elaborate on recommendations for finite element analysis for HPCBs. Design examples are appended to illustrate typical current practice using a 12 × 12 m grid floor with live load of 15 kPa. Various considerations for different parameters such as fire resistance are discussed. Finally, the authors present a case study of a recently completed industrial building in Singapore to quantify the benefits of using HPCBs over reinforced concrete and conventional composite construction. Structural engineering professionals, whose work relates to long-span and heavy-loading industrial or commercial buildings, will benefit from the detailed guidance and focus on practical applications provided throughout this book. Post-graduate students of advanced steel and composite structures will also benefit from these descriptions.
