Underground structures are always expensive to build, repair and maintain. However, these structures have significant value to society. As infrastructure they are directly responsible for wealth creation and the development of nations. Hence, they must be built with long life expectancy, which is related to their structural and waterproofing stabil...

Superabsorbent polymer (SAP) is attracting attention as a water-entraining admixture that reduces shrinkage or heals cracks in concrete. Cross-linked sodium polyacrylate SAPs, which are the most widely produced SAPs in the global market, are applicable as concrete admixtures. However, there have been contradictory results on the freeze–thaw resista...
