Abstract

The corrosion rate is the rate at which the corrosion process in a material spreads over a certain period by measuring using the weight loss method. The use of larger diameter reinforcing steel also means there is more surface exposed to the corrosive environment. Corrosion of reinforced concrete beams aims to determine the effect of corrosion rate and diameter of reinforcing steel on the bending moment strength of reinforced concrete beams. The research consisted of testing the bending moment strength of corroded reinforced concrete beams. The test object is in the form of a block measuring 15 x 15 x 60 cm with concrete quality f'c 22.27 Mpa. Using various reinforcing steel diameters, namely 8, 10, and D10. For each variation of reinforcing steel diameter, there are 3 test objects. The bending moment strength test was tested on 28-day-old concrete based on ASTM C78/C78M regarding the standard test method for flexural strength of concrete (using a simple beam with third-point loading). Corrosion of reinforcing steel with variations in reinforcing steel diameter can reduce the bending moment strength of reinforced concrete beams. The largest normal bending moment strength of a reinforced concrete beam is 6.98 kNm. The largest corroded bending moment strength was 6.42 kNm or decreased by 8.063% compared to normal reinforced concrete beams.
