Reinforcement corrosion causes destruction to the steel by a loss in cross section and rib height, which can affect bond between concrete. During repair of corrosion-damaged reinforced concrete members, protective coating is usually applied cleaned corroded steel. There is, however, little information available on performance coatings. Furthermore, effect their thickness other parameters like r...

A partial pre-rusted wire beam electrode (WBE) was designed to study the influence of rust layer on rebar corrosion in carbonated simulated concrete pore solution (SCPS). The results show that passive film generated steel area is more fragile than formed fine polished carbonaceous media. Nevertheless, pitting resulting from presence chloride ions still tends occur surface due local acidificatio...

As Ground Penetrating Radar (GPR) is increasingly employed for assessing the condition of bridge decks, quantifying and controlling the quality of GPR data becomes an important challenge. This paper uses a methodology to assess the accuracy of deck condition measures, and demonstrates the methodology in a case study involving real data. The latter are generated during GPR applications on a larg...

Strengthening of the existing seismically deficient reinforced concrete (RC) buildings is an important issue in earthquake prone regions. Addition of RC shear wall as infill or external walls into the structural system has been a commonly preferred strengthening technique since the Big Erzincan Earthquake occurred in Turkey, 1992. The newly added rigid infill walls act primarily as shear walls ...

Rock bolting has firmly used as the coal mine roof reinforcement in underground coal mine. The bolting effect of fully grouted rebar bolt is closely related to the bolt surface profile. This paper provides an experimental study to confirm that bolt rib internal length has great influence on bolting effect. Pull-out tests were conducted using rebar bolt with different rib spacings of 12, 24, 36 ...
