This book was released on 2016 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Bee‘ah‘s Waste Management Complex in the Emirate of Sharjah, UAE, has been producing aggregate from construction and demolition wastes for quite some time. However, such a product has not been utilized in structural applications. This research focuses on the concrete shear strength, which is a major component of the total shear resistance of reinforced concrete elements. Therefore, the objectives of this study are to investigate the behavior and develop design recommendations for the shear strength of reinforced concrete beams made with locally produced coarse aggregate. To do that, laboratory experiments on fifteen half-scale beams and associated theoretical predictive methods are utilized. The experimental part of the study addresses beams with different concrete compressive strengths, recycled coarse aggregate replacement percentages in the concrete mix, shear span-to-depth ratios and effective flexural steel reinforcement ratios. The experimental results are compared with corresponding findings from reinforced concrete beams employing natural aggregate. The theoretical part of the study considers available codified procedures for predicting the shear strength of concrete beams, such as the ACI 318 and CSA 23.3, as well as the strut-and-tie procedure, modified compression field theory and fracture mechanics approach. Results of the study showed that North American codes can adequately predict the shear strength provided by concrete when the shear span-to-depth ratio is large, but over-estimates it when the applied load is very close to the support. The strut-and-tie model predicted the shear strength of the tested beams much better than the other methods. The recycled concrete beams showed lower shear strength when the coarse aggregate replacement ratio was 50% and comparable shear strength when the replacement ratio was 100% than corresponding beams made with natural aggregate. The influence of concrete compressive strength on the shear capacity is much more predominant in the beams that were made with natural aggregate than those that were made with recycled aggregate. The effect of the flexural reinforcement ratio was not as significant in the beams made with concrete utilizing recycled aggregate as those made with natural aggregate. Until more tests on concrete beams made from different batches of recycled aggregate from Bee‘ah become available, a 30% reduction factor is suggested to be incorporated into the shear strength equations in the relevant codes."--Abstract.

This book was released on 2008 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quality and testing of materials used in construction are covered by reference to the appropriate ASTM standard specifications. Welding of reinforcement is covered by reference to the appropriate AWS standard. Uses of the Code include adoption by reference in general building codes, and earlier editions have been widely used in this manner. The Code is written in a format that allows such reference without change to its language. Therefore, background details or suggestions for carrying out the requirements or intent of the Code portion cannot be included. The Commentary is provided for this purpose. Some of the considerations of the committee in developing the Code portion are discussed within the Commentary, with emphasis given to the explanation of new or revised provisions. Much of the research data referenced in preparing the Code is cited for the user desiring to study individual questions in greater detail. Other documents that provide suggestions for carrying out the requirements of the Code are also cited.

This book was released on 2021-12-01 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: This book describes how, given the global challenge of a shortage of natural resources in the 21st century, the recycling of waste concrete is one of the most important means of implementing sustainable construction development strategies. Firstly, the book presents key findings on the micro- and meso-structure of recycled aggregate concrete (RAC), while the second part focuses on the mechanical properties of RAC: the strength, elastic modulus, Poisson’s ratio, stress-strain curve, etc. The third part of the book explores research on the durability of RAC: carbonization, chloride penetration, shrinkage and creep. It then presents key information on the mechanical behavior and seismic performance of RAC elements and structures: beams, columns, slabs, beam-column joints, and frames. Lastly, the book puts forward design guidelines for recycled aggregate concrete structures. Taken as a whole, the research results – based on a series of investigations the author has condu cted on the mechanical properties, durability and structural performance of recycled aggregate concrete (RAC) over the past 10 years – demonstrate that, with proper design and construction, it is safe and feasible to utilize RAC structures in civil engineering applications. The book will greatly benefit researchers, postgraduates, and engineers in civil engineering with an interest in this field.

Book excerpt: Sustainable Construction Materials: Recycled Aggregate focuses on the massive systematic need that is necessary to encourage the uptake of recycled and secondary materials (RSM) in the construction industry. This book is the fifth and the last of the series on sustainable construction materials and like the previous four, it is also different to the norm. Its uniqueness lies in using the newly developed, Analytical Systemisation Method, in building the data-matrix sourced from 1413 publications, contributed by 2213 authors from 965 institutions in 67 countries, from 1977 to 2018, on the subject of recycled aggregate as a construction material, and systematically analysing, evaluating and modelling this information for use of the material as an aggregate concrete and mortar, geotechnics and road pavement applications.
