Investigation of Graphene Derivatives on Electrical Properties of Alkali Activated Slag Composites

Results showed that rGO nanosheets addition can significantly improve the yield stress, plastic viscosity, thixotropy, and compressive strength of the AASC, and the effect of graphene oxide (GO) on the A ASC is studied and the results indicated that the agglomeration of GO nanOSheets largely inhibited the application of it, even with a small dosage.

Evaluation of electrode-sample contact impedance under different curing humidity conditions during measurement of AC impedance of cement-based materials

The results indicated that when using the saturated calcium hydroxide solution (SCH) as conductive medium, the contact impedance in the four-point measurement is negligible for the impedance range of cement-based materials.
