Image-Based Crack Morphology Characterisation for Electrical Failure Analysis in Conductive Polymer Composites
Abstract: Electrical performance in conductive polymer composites is strongly governed by crack-network evolution, yet failure analysis typically relies on qualitative image inspection or electrical anomaly detection in isolation. This work proposes an end-to-end framework that converts optical/SEM crack imagery into a standardised crack morphology signature and quantitatively links it to electrical degradation indicators. A two-stage learning strategy is adopted: crack-representation pretraining using the public Concrete Crack Images for Classification dataset, followed …

Use of Geopolymer Composites for Controlling Structural Cracks
Abstract: A building’s safety and stability can be compromised by ignoring the potential structural issues indicated by occurring cracks in buildings. Extensive damage may cause over the period from unidentified cracks.Good quality concrete never cracks in normal service conditions unless high horizontal force is applied. Through the cracks, carbon dioxide is released into the concrete and speeds up carbonation throughout the cracks, thus reducing the structure usage. The materials which are …
