Abstract
Corrosion due to the loss of reinforcement diameter has an influence on flexure and shear capacity in reinforcement concrete. One of the corrosion causes is concrete cracks. Moreover, corrosion in reinforcement can causes expansive pressure worsen condition of the structure. This research investigate shear capacity of 4 reinforced concrete beams with dimensions of 200 x 10 x 20 cm. There were 2 beams exposed to 3.5% NaCl by galvanostatic method with constant current of 0.1 ampere for one month and 2 beams without exposure. Furthermore, four point bending test with shear span-effective depth ratio (a/d) under 2.5 will be applied. The test results showed that shear compression occurs along 2/3 of shear span, beams with exposure has shear capacity 35% and compression strength 8% lesser than beams without exposure.
