Abstract
Corrosion of reinforcing steel affects the strength of the structure. Reinforcing steel that rusts causes the function of the reinforcement to decrease. This study aims to determine the effect of the thickness of concrete blankets as reinforcement protection on the corrosion rate of reinforcing steel and the bending moment of corroded reinforced concrete beams, using test specimens measuring 15 x 15 x 65
cm with a concrete quality of 20.75 Mpa. The thickness of the concrete blanket used in this study is 10 mm, 15 mm and 25 mm with each thickness there are 5 test pieces. To accelerate the corrosion of reinforcement, 3.5% NaCl solution and
galvanostatic method were used. The tests carried out were bending moments carried out at 28 days of concrete age based on ASTM C78/C78M and corrosion date testing based on ASTM G 31-72 weight loss method. The highest bending
moment was 5.50 kNm in the reinforced concrete beam with 25 mm concrete blanket thickness and the lowest was 4.68 kNm in the reinforced concrete beam with 10 mm concrete blanket thickness. The highest corrosion rate was 28214.63
mpy in reinforced concrete beams with concrete blanket thickness of 10 mm and the lowest was 3977.34 mpy in reinforced concrete beams with concrete blanket thickness of 25 mm.
