Abstract: This paper reports on the accuracy of new test methods developed to measure the air and water permeability of high-performance concretes (HPCs). Five representative HPC and one normal concrete (NC) mixtures were tested to ...

Abstract: The durability of reinforced concrete structures depends, in the main, on the performance of the cover-zone concrete, which protects the steel from the external environment. This paper focuses on the use of discretized ...

Abstract: The performance of the surface zone of concrete is acknowledged as a major factor governing the rate of deterioration of reinforced concrete structures because it provides the only barrier to the ingress of water containing ...
