Steel Corrosion in Calcium Aluminate Cement Mortar against

Jan 01, 2021· Three different types of calcium aluminate cement (CAC) were investigated about their resistance to chloride-induced corrosion of steel. CAC imposed higher corrosion resistance compared with ordinary portland cement (OPC). The corrosion current density in CAC was nearly indiive of the passivity, ranging below 1.0 mA/m2 (6.45 × 10–4 mA/in
