Stabilisation of Sulfide‐Bearing Clays as a New Building Ground
European Journal of Soil Science, Volume 77, Issue 1, January–February 2026.ABSTRACT Fine‐grained, sulfide‐bearing marine clays are found along the Finnish coastline. When excavated and exposed to air, the sulfides within these soils react with oxygen to form sulfuric acid. Such soils are classified as hypersulfidic soils.

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.Abstract The redox potential of the pore solution of hardened cements containing ground granulated blast furnace slag (GGBFS) affects reinforcement corrosion and immobilization of radioactive waste. Here, Mn K‐edge X‐ray absorption near‐edge structure (XANES) spectroscopy was applied to determine the depth profile of the oxidation state of manganese in
