Pore solution study has been carried out on 2.43 and 14% C3A hardened cement pastes. Data have been analyzed in conjunction with the data developed in two pore solution studies made by Page and Vennesland and Diamond using 7.37 and 9.1% C3A mature cement pastes. The results show that C3A and alkali

## Abstract This paper provides a brief review of research aimed at characterising the steelβconcrete interfacial zone (SCIZ) and its influence on the susceptibility of the metal to pitting corrosion when concrete is exposed to environments that cause ingress of chloride ions accompanied by leachin
Chloride binding and its influence on the rate of reinforcement corrosion has been investigated in a range of mixes by, respectively, pore solution analysis and measuring the galvanic current in macro corrosion cells formed by embedding mild steel bars in two layers of concrete. For chloride derived
Steel reinforcement electrodes embedded in different matrices of concrete were exposed to simulated marine splash zone exposure for about 600 days (1200 cycles) after initial curing in air for 14 days. The corrosion potentials and polarisation resistance were monitored at regular intervals to determ
## Abstract Measurements have been made with mortar specimens with light aggregates (LWA) and the cements Norcem HS65 and MP30, corresponding to CEM I and CEM II. The w/b ratio was 0.30 and 0.40 and in one mix prewetted LWA was used. The silica fume addition was 8%. The specimens have two sets of e
## Abstract A literature survey has lead to the conclusion that a theory which postulates an increased anodic reactivity on a local site in the passive film is very probable. Experiments have been set up to confirm these suggestions. By means of the electronβmicroanalyser, it is shown that CI^β^ion
