Transport properties of concrete : measurements and applications /
Transport Properties of Concrete covers how to measure the ability of ions and fluids to move through concrete material, and how to use the results to model performance. These transport properties largely determine the durability of concrete and of steel embedded within it, as well as the effectiven...
