## Abstract
Abstract In this paper, In this paper, effects of vibration time (0, 10 and 20 seconds) on compressive strength and corrosion resistance of steel bar in concrete are experimentally investigated. Compressive strength of concrete was performed on cylindrical specimens of Ø100x200 mm with water cement ratio (w/c) 0.52 after 28 days curing in tap water. Cylindrical specimens of Ø100x200 mm having 16 mm diameter of steel bar are considered for corrosion study. The specimens were subjected to cyclic wetting and drying regime up to 15 cycles. In wet cycle the specimens are immersed in sea water for 3 days, while in dry cycle the specimens were placed in open air for 4 days. The corrosion activity is monitored by measuring the copper/copper sulphate (CSE) half-cell potential according to ASTM C-876. The chloride penetration depths of concretes are also measured after 28 days immersed in 10% NaCl solution. Results show that compressive strength, chloride penetration depths and corrosion of steel bars is significantly affected by vibration time.
