Abstract

Beton bertulang merupakan material yang sering digunakan untuk bangunan. Korosi baja tulangan pada beton bertulang dapat menyebabkan kerusakan pada struktur beton itu sendiri, sehingga dari segi ekonomi sangat merugikan. Oleh karena itu diperlukan suatu sistem perlindungan pada tulangan terhadap serangan korosi. Salah satu proteksi korosi pada beton bertulang adalah dengan penambahan inhibitor. Pada penelitian ini dipelajari pengaruh pemberian inhibitor dan metodenya terhadap korosi beton bertulang. Spesimen yang digunakan adalah beton yang mempunyai rasio air-semen (w/c ratio) 0,5. Beton berbentuk silinder pejal berukuran panjang 120 mm dan diameter 50,8 mm (2 inch). Baja profil berdiameter 9,5 mm dan panjang 120 mm dipilih sebagai tulangan beton. Pengkondisian ialah perendaman spesimen beton bertulang di larutan NaCl 12,5 % dengan memberikan arus sebesar 5 mA. Digunakan dua metode pemberian inhibitor yaitu sebelum pengkondisian dan setelah pengkondisian selama 10 hari. Pengkondisian lanjutan dilakukan selama 60 hari. Monitoring korosi pada baja tulangan yang digunakan ialah half-cell potensial dan resistivity beton. Spesimen yang diberi Inhibitor dengan cara preventif (awal sebelum pengkondisian korosi) dan korektif (diberi setelah 10 hari pengkondisian), mempunyai kecenderungan korosi lebih rendah dibandingkan dengan spesimen tanpa diberi inhibitor. Metode pemberian inhibitor dengan preventif mempunyai kecenderungan korosi' lebih rendah dibandingkan dengan korektif

Reinforced concrete is a material that is often used for buildings. Corrosion of reinforcing steel in reinforced concrete can cause damage to the concrete structure itself, so from an economic perspective it is very detrimental. Therefore, a protection system is needed for the reinforcement against corrosion attacks. One way of protecting corrosion in reinforced concrete is by adding inhibitors. In this research, the effect of inhibitor administration and its method on reinforced concrete corrosion was studied. The specimen used is concrete which has a water-cement ratio (w/c ratio) of 0.5. The concrete is in the form of a solid cylinder measuring 120 mm long and 50.8 mm (2 inch) in diameter. Profiled steel with a diameter of 9.5 mm and a length of 120 mm was chosen as concrete reinforcement. Conditioning is immersing reinforced concrete specimens in 12.5% NaCl solution by providing a current of 5 mA. Two methods of administering inhibitors were used, namely before conditioning and after conditioning for 10 days. Follow-up conditioning was carried out for 60 days. Corrosion monitoring of the reinforcing steel used is half-cell potential and concrete resistivity. Specimens that were given inhibitors in a preventive (initial before corrosion conditioning) and corrective (given after 10 days of conditioning) method had a lower corrosion tendency compared to specimens without inhibitors. The preventive method of administering inhibitors has a lower corrosion tendency compared to the corrective one
