Effects of leaching and chloride migration on the microstructure and pore solution of blended cement pastes during a migration test

•Chloride migration induced porosity changes up to 60% in pastes with mineral additions.•During chloride migration, new salts occupy the porosity of cement pastes used in the range 7–70 nm.•The kinetics of calcium release, expressed as a flux, ranged from 1.8 × 10−2 to 1.2 × 10−1 mmol.m−2.s−1. This...
