Chloride ingress rate and threshold content, as determined by the ‘Integral’ test method, in concrete with several w/c ratios in saturated and unsaturated conditions

The ‘integral’ test method aims at the simultaneous determination of the chloride migration rate and chloride threshold content. This information is required for durability performance design of reinforced concrete structures in the marine environment. Standard tests are generally designed to be applied on saturated samples to improve their repeatability and reproducibility, but this condition differs from the actual conditions of depassivation...
