Reinforcement Corrosion Rate in Cracked Areas of RC-Members Subjected to Sustained Load
The results of measuring the reinforcement corrosion rate of reinforced concrete beam and slab specimens subjected to sustained load are presented in this paper. Beam and slab specimens were subjected to corrosion of reinforcement under controlled conditions in an environmental chamber, where corrosion was initiated and accelerated in cycles of spraying with sodium chloride solution and drying the specimens. Cracks in concrete were caused by sustained load. During the experiment reinforced concrete samples were cracked, except near the supports, in area with small bending moments. A significant effect of increasing of corrosion rate due to presents of cracks was observed. The corrosion rates in uncracked areas of specimens were significantly smaller than in the cracked areas of the same specimens. The corrosion rate was measured by using galvanostatic impulse method. The measuring points were distributed along the beam and slab specimens. In this paper the influence of cracks on the time of initiation of corrosion and corrosion rate is analysed. Also, the relation between the measured values of the half-cell potential and corrosion rate is investigated. The results presented in the paper are part of the comprehensive experimental research.
