TL;DR: In this article, a comprehensive review of the acoustic emission (AE) technique for its applications in concrete structure health monitoring is presented, with highlights on the limitation of the individual parameter-based approaches when adopted on site.

TL;DR: The capability of the AE technique to detect corrosion occurring in real-time makes it a strong candidate for serving as an efficient NDT method, giving it an advantage over other NDT methods.

TL;DR: In this paper, the use of metakaolin and silica fume as supplementary cementing materials in enhancing the near surface properties of concrete was investigated, and the results showed that the inclusion of these materials greatly reduced the initial surface absorption, water absorption and sorptivity of concrete in varying magnitudes.

TL;DR: In this paper, acoustic emission (AE) technique is used for monitoring and evaluating the influence of corrosion on the structural behavior of steel reinforced concrete (RC) beams under three-point flexure test.

TL;DR: In this article, fiber reinforced concrete beams loaded under flexure were monitored using both the acoustic emission (AE) and travel time tomography (TTT) techniques, with the primary aim to evaluate the development of fracture in beams in a non-destructive manner.
