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

The self-sensing of compressive and flexural stress in cement-based materials (without embedded or attached sensors, without admixture requirement and without poling) by capacitance measurement has

Preparation and Properties of Waterborne Polypyrrole/Cement Composites

Waterborne polypyrrole (WPPy) was prepared via the chemical oxidative polymerization with three kinds of hydrophilic agents: sodium lignosulfonate (LGS), sodium dodecyl sulfonates (SDS), and sodium dodECyl sulfate (SLS), and then WPPy/cement composites were prepared by mixing cement with it.

Piezoresistive properties of cement-based sensors: Review and perspective



Effect of admixtures on the dielectric constant of cement paste

Degree of Dispersion of Latex Particles in Cement Paste, as Assessed by Electrical Resistivity Measurement

The degree of dispersion of latex particles in latex-modified cement paste was assessed by measurement of the volume electrical resistivity and modeling this resistivity in terms of latex and cement

An experimental and mesoscopic lattice simulation study of styrene-butadiene latex-cement composites properties

The consequences of styrene-butadiene rubber (SBR) latex addition on the hardness and structural properties of a cement matrix have been investigated. The results show that the primary effect of

Dielectric Permittivity of Various Cement-Based Materials during the First 24 Hours Hydration

The dielectric permittivity of cementitious materials during 24 hours hydration period at a frequency of 2.45 GHz using a network analyzer with open-ended probe technique was measured. Influences

Electrical resistance and microstructure of latex modified carbon fiber reinforced cement composites

The electrical resistance, flexural strength, and microstructure of carbon fiber reinforced cement composites (CFRC) were improved greatly by adding water-redispersible latex powder. The electrical

Electric polarization in carbon fiber-reinforced cement

Vibration damping admixtures for cement

The loss and storage moduli, and tan (delta) , of cement pastes were measured at 25 to 150 degrees Celsius and 0.2 to 2.0 Hz. The addition of latex or methylcellulose increases all three quantities,

Latex influence on the mechanical behavior and durability of cementitious materials

Abstract The results of an experimental program conducted on latex-modified mortars are presented in this article. These mortars have become of growing interest in the field of construction. They
