Electrochemical impedance behavior and transport properties of silica fume contained concrete
Highlights Effect of silica fume as a supplementary cementitious material on transport properties and electrochemical behavior of concrete was studied. The correlations between electrochemical behavior parameters and transport properties were evaluated. Improvements in concrete properties due to use of silica fume was compared with those due to decreases in w/cm.
Abstract The research study presented herein evaluates electrochemical impedance behavior and transport properties of silica fume contained concretes. The correlation between electrochemical parameters and transport properties is also studied. The test results revealed considerable improvements in transport properties, electrochemical responses and corrosion rate of the studied mixtures when silica fume was used as a supplementary cementitious material and/or w/cm was decreased. The improvements due to inclusion of silica fume were lower than those related to decrease in w/cm. Electrolyte resistance, polarization resistance, and resistance to charge transfer showed their highest correlations with rapid chloride permeability, water absorption and water permeability, respectively.
