... in chloride environments. Structural concretes with up to 60% coarse CCA (and CEM I, CEM II/B-V and CEM III/A binders) were exposed to aggressive chloride environments and monitored with electrochemical techniques and subsequent destructive testing to determine their risk of corrosion initiation. The results...

... to corrosion risk assessment. An independent appraisal of the site performance of hybrid anode corrosion protection systems (UK invention disclosed in Patent GB2426008B) was conducted on six bridge structures in 2014. The aim of the study was to investigate the effectiveness of current design approaches...
