Abstract

Hardened cement paste with various inorganic electrolytes was prepared for investigating the effect of pore structure and pore solution on electric conductivity and transport properties. As a result, it was shown that the correlation between the total pore volume measured by mercury intrusion method and the apparent diffusivity of the chloride ion of hardened cement paste was low. On the other hand, it was shown that relationship between the diffusivity of the chloride ion and electric conductivity of the hardened cement paste by the AC impedance method was linear as reported Nernst-Einstein equation. From this result, it was shown that it is possible to estimate the diffusivity of hardened cement paste by the electric conductivity measurement even if pore structure and pore solution of hardened cement paste changed.
