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 chloride migration rate and threshold content. This information is required for durability performance design reinforced concrete structures in marine environment. Standard tests are generally designed to be applied on saturated samples improve their repeatability reproducibility, but this condition differs from actual conditions depassivation service. paper compares results made with ordinary Portland cement a water-to-cement ratio ranging 0.35–0.50, preconditioned full saturation degree 77%. Results contrasted properties commonly associated its concerning ingress. variation range 77–100% showed greater effect ingress than determined decreases increasing w/c ratio. • Correlation between Determination content by integral (un)saturated specimens. Equal efficacy detecting pitting half-cell potential corrosion current. transport content, sorptivity, compressive strength, electrical resistivity.
