Durability Evaluation of Concrete Mixes with High Volume Fly Ash (HVFA)

This report evaluates the ionic transport properties of various high volume fly ash -HVFA- concretes. Different numerical simulations were performed on the findings to predict the time to corrosion initiation of rebar for each concrete mix under different exposures. Tests showed that under Arabian Gulf conditions the onset of corrosion occurs first under Parking and Groundwater then Submerged and Tidal zone scenarios however it is noted that availability of oxygen is a key factor which can change the significantly delay or completely prevent corrosion from occurring in some scenarios. This report was part of the EcoSmart UAE Test Series
