 alkali-activated slag, AAS, has emerged as a potential replacement for conventional Portland cement, OPC, due to its lower carbon footprint and reduced waste generation. AAS also exhibits improved performance in terms of thermal and chemical resistance, as well as early age cracking and drying shrinkage. However, it is still unclear whether AAS can be used as a viable alternative to OPC in terms of its self-healing capabilities. This paper reviews the current state of knowledge on the self-healing mechanisms of AAS and compares them with those of OPC. The authors conclude that AAS has the potential to be a viable alternative to OPC, but further research is needed to fully understand its self-healing capabilities.
