High electric permittivity of polymer-modified cement due to the capacitance of the interface between polymer and cement

The electric permittivity is a material property that relates to the dielectric and electromagnetic behaviors. This work reports the effect of polymer admixtures on the permittivity (2 kHz) of cement

Capacitance-based defect detection and defect location determination for cement-based material

This paper provides the first report of capacitance-based nondestructive cement-based material defect detection. It is based on the use of the fringing electric field (2 kHz) of a capacitor that

Capacitance-based nondestructive detection of aggregate proportion variation in a cement-based slab

Capacitance-based stress self-sensing in cement paste without requiring any admixture

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.

Theory of piezoresistivity for strain sensing in carbon fiber reinforced cement under flexure

A theory is provided for piezoresistivity in carbon fiber reinforced cement (with and without embedded steel reinforcing bars) under flexure (three-point bending). The phenomenon, which involves the

Electromagnetic wave-based measurement techniques to study the role of Portland cement hydration in cemented paste backfill materials

Variations in electrical conductivity and real relative permittivity of cemented paste backfill (CPB) at early times of cement hydration are studied using non-destructive, electromagnetic wave-based
