交流阻抗谱表征磨细矿渣胶凝活性的研究

Study of Cementitious Activity of Granulated Blast Furnace Slag by AC Impedance Technique

矿物掺合料的胶凝活性可以用交流阻抗谱来表征.以磨细矿渣为例,可以通过对其CaO的电导、C-S-H凝胶的电容以及频率相角的测定来了解其胶凝活性.

Granulated blast furnace slag was chosen as a typical kind of mineral admixture for the research of cementitious activity by AC impedance technique. It is shown that the conductance of the soluble CaO, the capacitance of the C-S-H and the phase angle, which are obtained from the complex impedance plot, can be used to characteristic the cementitious reactivity of the specimens.
