Pierre-Claude Aïtcin is Professor Emeritus at the University of Sherbrooke, a member of the Canadian Academy of Engineering, a Fellow of the Canadian Society of Civil Engineering, and an Honorary Member of the American Concrete Institute. He was the Scientific Director of Concrete Canada, the Network of Centres of Excellence on High-Performance Concrete for 8 years. For nine years, he also held an Industrial Chair on Concrete technology in collaboration with thirteen industrial partners. He is the author of the books:
- High-Performance Concrete published in 1998 by E and FN SPON of London. A Portuguese, French, Czech and Spanish version of this book have been published, a Chinese one is under preparation.
- Binders for durable and sustainable concrete published in 2008 by Taylor and Francis of London,
- Sustainability of concrete(coauthored with Sidney Mindess published in February 2011 by E and FN SPON of London His principal research interests were the manufacturing and use of high-performance and ultra-high-performance concretes, and the use of industrial by-products in concrete.
It is easy to demonstrate that High Performance Concretes (HPC) are more sustainable than Normal Strength Concretes (NSC): building a plain unreinforced column with a 75 MPa concrete requires 2 times less cement and three times less aggregates to sustain the same load. Moreover as HPCs, when they are well cured, are much less porous and impervious than NSCs there are more durable and consequently the service life of HPC structures is much longer than that of NSC ones. We have now the scientific comprehension and technology to increase substantially and quite easily the sustainability of concrete structures. Examples of modern sustainable structures will be presented.
