Abstract EN
A chloride-binding capacity is the major factor to mitigate the ingress of chloride into concrete.
This paper presents the chloride-binding capacity of Portland cement paste containing synthesized CA2 (CaO·2Al2O3).
The CA2 was synthesized in the high-temperature furnace and characterized by X-ray diffraction for inspecting the purity.
The synthesized CA2 was substituted for Portland cement by 0%, 5%, and 10% by weight, and the NaCl solution was used as an internal chloride, which is assumed as a total chloride.
The chloride-binding capacity of cement paste was calculated from a water-soluble chloride extraction method by the application of the Langmuir isotherm equation.
And the hydration products were analyzed using X-ray diffraction and thermogravimetric analysis.
We demonstrate that the CA2 increases an AFm phase in the Portland cement system, and the incorporation of CA2 consequently enhances the chloride-binding capacity of cement paste samples.
