| סיכום: | Title screen The article examines damage caused to steel and fiberglass reinforcement concrete by freeze-thaw cycles in saline medium conditions. After 12 freeze-thawing cycles, the concrete-rebar bond strength decreases by 30% for steel and by 40% for fiberglass. A method of evaluating the concrete-rebar bond strength is proposed. The evaluation procedure is based on measuring electric response to mechanical impact. Energy attenuation coefficient and the signals' spectrum centroid could be used as the diagnostic criteria for the evaluation of concrete-rebar bond strength. After 12 FT cycles the electric signal's energy attenuation coefficient increases by about 40–45%, and the maximum signals' spectrum centroid increasing reaches about 8 kHz. The proposed method can be used to monitor the evolution of concrete-rebar bond strength in complex climate testing conditions. Режим доступа: по договору с организацией-держателем ресурса |
