Abstract

The function and performance of self-diagnostic composites embedded in concrete blocks and piles were investigated by bending tests and electrical resistance measurement. Carbon powder (CP) and carbon fiber (CF) were introduced into glass fiber reinforced plastic (GFRP) composites to provide electrical conductivity. The CPGFRP composite displays generally good performance in various bending tests of concrete block and piles compared to the CFGFRP composite. The electrical resistance of the CPGFRP composite increases remarkably at small strains in response to microcrack formation at about 200 μm strain, and can be used to detect smaller deformations before crack formation. The CPGFRP composite shows continuous change in resistance up to a large strain level just before the final fracture for concrete structures reinforced by steel bars. It is concluded that self-diagnostic composites can be used to predict damage and fracture in concrete blocks and piles.

Additional information

This article [1] has been retracted at the request of the Editor-in-Chief. Concerns were raised regarding substantial duplications with previous articles published in other journals in which for some S.-G. Shin is one of the co-authors. After a thorough analysis we conclude that the concerns are valid. The article contains sections that substantially overlap with the following published article [2] (amongst others). S.-G. Shin has not responded to correspondence from the Editor about this retraction.
