Investigation on influential factors on chloride concentration index of cement-based materials by pore solution expression method

In this study, the effects of different factors on chloride concentration index (Nc) of cement paste were studied. The factors including chloride concentration in soaking solution, slag replacement, external applied voltage and cation ions of soaking solution were all studied from the electrical double layer (EDL) properties point of view. Zeta potential and proton Nuclear Magnetic Resonance (1H NMR) measurements were conducted to investigate...
