Influences of chloride immersion on zeta potential and chloride concentration index of cement-based materials

This paper measured the zeta potential and chloride concentration index of hardened cement paste, which was defined as the ratio of chloride concentration in the expressed pore solution to that in soaking solution. A model was proposed to explain the relationship of zeta potential and concentration index of hardened cement pastes immersed in chloride solution. The results showed that with the increase of chloride concentration in soaking...
