Chloride ingress and steel corrosion in cement mortars incorporating low-quality fly ashes
In this study, the microstructure and hydration characteristics of ecocement and normal Portland cement mortars blended with low-quality fly ashes were investigated. In addition, the corrosive behaviours of steel bars embedded in the mortars were studied. Several tests including scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis and differential scanning calorimetry (DSC) were used for the characterization of the mortars. Electrochemical measurement such as linear polarization resistance and AC impedance spectroscopy were also used to monitor the corrosive behaviours of the embedded steel bars in the mortars. The chloride ingress into the mortars was also studied. The results of the various tests are discussed.
