Publisher's Synopsis
Durability and service life design of concrete constructions have considerable socio-economic and environmental consequences, in which the permeability of concrete to aggressive intruders plays a vital role.
This book provides a deep insight into the permeability of concrete, moving from theory to practice, including real cases such as the Port of Miami Tunnel and Hong Kong-Zhuhai-Macao link. It stresses the importance of site testing for a realistic durability assessment, and details the so-called "Torrent Method" for non-destructive measurement of air-permeability.
- Should the coefficient of permeability be expressed in m² or m/s?; Poiseuille or Darcy?
- how can we get an "average" pore radius of concrete from gas-permeability tests?
- why should permeability be measured on site?
- how can service life of structures be predicted by site testing of air-permeability and cover depth?
Practitioners will find stimulating examples on how to predict the coming service life of new structures and the remaining life of existing structures, based on site testing of air-permeability and cover thickness. Researchers will value the principles of permeability testing as well as how this reflects the influence of concrete mix composition and processing.
