Pengaruh Konsentrasi Ekstrak Daun Tembakau Sebagai Inhibitor Pada Tulangan Beton Bertulang

Reinforced concrete structures that are destroyed due to corrosion attacks need serious handling. One method of preventing is by using an inhibitor. In this study, the inhibitors used were tobacco leaf extract with variations 0%, 4% and 8%. The analyze rate occurs weight loss method. Tests carried out providing electricity test object a voltage 5V. results showed influence addition at concentrations 8% was able reduce density anodic cathodic currents which resulted in reduced steel reinforcement. This proves can be as green inhibitor because it effectively decreases rate.
