Available in PDF, EPUB and Kindle. Book excerpt: Understanding and recognising failure mechanisms in concrete is a fundamental pre-requisite to determining the type of repair, or whether a repair is feasible. This title provides a review of concrete deterioration and damage, as well as looking at the problem of defects in concrete. It also discusses condition assessment and repair techniques.Part one discusses failure mechanisms in concrete and covers topics such as causes and mechanisms of deterioration in reinforced concrete, types of damage in concrete structures, types and causes of cracking and condition assessment of concrete structures. Part two reviews the repair of concrete structures with coverage of themes such as standards and guidelines for repairing concrete structures, methods of crack repair, repair materials, bonded concrete overlays, repairing and retrofitting concrete structures with fiber-reinforced polymers, patching deteriorated concrete structures and durability of repaired concrete.With its distinguished editor and international team of contributors, Failure and repair of concrete structures is a standard reference for civil engineers, architects and anyone working in the construction sector, as well as those concerned with ensuring the safety of concrete structures. - Provides a review of concrete deterioration and damage - Discusses condition assessment and repair techniques, standards and guidelines

Download or read book Recycled Aggregate Concrete Structures written by Jianzhuang Xiao and published by Springer. This book was released on 2017-11-13 with total page 670 pages. 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.

This book was released on 2010-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative book provides a comprehensive review of the highly important subject of non-destructive evaluation of reinforced concrete structures. Engineers have a range of sophisticated techniques at their disposal to assess the condition of reinforced concrete structures that do not cause material damage and which usually enable the structure to be used while the surveys are carried out. Non-destructive evaluation of the infrastructure also plays a key role in calculating and prioritising where money should be spent on repair or replacement. Providing details of related techniques and case studies, this book offers an overview of how to plan and implement the NDT of reinforced concrete structures.
