- The paper described the development of novel polymeric microcapsules for promoting self-healing in concrete. The proposed system has switchable mechanical properties, flexible when saturated and brittle when dried. Research addressed the problem of microcapsule survivability under severe high shear during concrete. Further, biopolymers (such as Arabic gum and calcium alginate) were used to produce these microcapsules addressing genuine sustainability concerns around the use of other approaches in bulk application in concrete. This work paved the way for the first systematic analysis on this area (https://doi.org/10.1016/j.conbuildmat.2016.06.119) and also enabled the large scale use of microcapsules at industrial level (https://doi.org/10.1016/j.conbuildmat.2019.02.178).
