Abstract
The corrosion of aluminum alloys in mortar has been studied from the measurements of weight loss and electrochemical characters. In mortar without NaCl, the corrosion of alloys was controlled by the accumulation of corrosion products and its rate was proportional to the passivation current. The corrosion behavior agreed very well with that observed in saturated Ca(OH)2 solution. On the other hand, the corrosion of alloys in mortar containing NaCl was not controlled by the accumulation of corrosion products. The weight loss of aluminum alloys increased linearly with increasing immersion time and showed the following sequence; Al-Cu>Al-Zn≈Al>Al-Mg>Al-Mn>Al-Mg-Si.
