| Outline of Final Research Achievements |
In this study, the effect of microstructure on transport properties of hardened cement paste was investigated. Hardened cement paste mixed with inorganic electrolytes, blast furnace slag, and fly ash was investigated, and it was found that Calcium silicate hydrate(C-S-H) and pore solution composition had an influence on the transport properties as well as pore structure. The chloride adsorption ability of the hardened cement paste during calcium leaching decreased remarkably in comparison with before leaching, and it was clarified that the adsorption ability of C-S-H is depended on the Ca/Si ratio of C-S-H in the blended cement.
