Resistance of alkali-activated slag mixed with wastewater towards biogenic sulfuric acid attack

The role of Ni and Cr wastewater on the mitigation of the deterioration rate of alkali-activated slag (AAS), caused by biogenic sulfuric acid produced by a sulfur oxidizing fungus (SOF: Aspergillums Niger), is evaluated. The cationic leaching rate, the fungal biomass and the pH of a medium are the c...
