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 conducted 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.
Dr. Jianzhuang Xiao is a Professor of Civil Engineering at Tongji University, Shanghai, PR China. He received his B.Sc., M. S. and Ph.D. degrees in Civil Engineering from Tongji University in 1989, 1995 and 1997 respectively. He gained essential industrial experience at companies like Shandong Textile Building Design Institute and Tongji Project Management Company before joining the faculty of Tongji University in 1997.
Dr. Xiao's main areas of research are in the material behavior and structural performance of recycled aggregate concrete, aspects he has been exploring for the past 15 years. He is the author or co-author of more than 300 papers on material properties and material behavior, interfacial layer mechanisms, and modeled recycled aggregate concrete. He also authored one English-language monograph, and is currently consulting many companies who are interested in recycling their construction and demolition waste.
He was the recipient of the 2013 Distinguished Young Scholars of China Award from the National Natural Science Foundation of PR China and a 2004 Alexander von Humboldt Foundation fellowship in Germany. He currently serves as a Board Member for the International Journal of Sustainable Development and Planning
, Journal of Building Engineering
and Journal of Zhejiang University
. He was awarded three first-class and six second-class Awards for Scientific and Technology Progress in China, and holds 15 authorized national invention patents. Currently he is serving as the Chairman of RILEM TC for Structural Behaviour and Innovation of Recycled Aggregate Concrete and as director of the Recycled Aggregate Concrete Committee in PR China. Moreover, he edited the first Technical Code for Recycled Aggregate Concrete in PR China.
