Pore Structure Characterization and Environmental Assessment of Ground Volcanic Pumice-Based Alkali-Activated Concrete

Abstract The impact of pore structure and its connectivity in ground volcanic pumice (GVP) and nano-silica (nSi)-based AAB on the chloride diffusion leading to corrosion of reinforcing steel for a period of up to 2.5 years was investigated in this study. 1H proton NMR relaxometry was employed as an...
