<p>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.</p><p><i>Concrete Permeability and Durability Performance</i> provides deep insight into the permeability of concrete, moving from theory to practice, and presents over 20 real cases, such as Tokyo¿s Museum of Western Art, Port of Miami Tunnel and Hong Kong-Zhuhai-Macao sea-link, including field tests in the Antarctic and Atacama Desert. It stresses the importance of site testing for a realistic durability assessment and details the "Torrent Method" for non-destructive measurement of air-permeability. It also delivers answers for some vexing questions:</p><ul><li>Should the coefficient of permeability be expressed in m¿ or m/s?</li><li>How to get a "mean" pore radius of concrete from gas-permeability tests?</li><li>Why should permeability preferably be measured on site?</li><li>
