Abstract:This study was aimed at investigating the influence of chemical activators on compressive strength and chloride-ion penetrability on binary and ternary concrete compositions, whose pore solution composition, electrical conductivity and total mercury intrusion volume were also determined. The chemically activated mixtures displayed higher chloride-ion penetrability and potassium sulfide was identified as the most effective activator. The study also showed that for a given mixture the influence of total porosity on chloride-ion penetrability was greater than the influence of specific conductivity of the pore solution.
