This study introduces the use of combined impressed current cathodic protection–structural strengthening (ICCP-SS) as a technique for repairing reinforced concrete structures that have been subjected to chloride-induced corrosion. The development this is based on combination carbon-fiber mesh (CF-MESH) and polymer-modified cementitious matrix produce carbon-fiber-reinforced (C-FRCM). First, effects different types amounts high molecular weight polymer short chopped carbon fibers flexural...
This study aims to investigate shear performance and prediction model of CFRP-ECC-concrete composite interface suffered from anodic polarization environmental degradation. The effect ECC mixtures, cathodic current densities, period, the duration sulfate soaking attacking by wet dry cycles on were studied. results showed that three failure modes found. Shear load-slip curves double broken lines characteristics, while voltage-deterioration time an approximate linear increase relationship...
The alumina doped epoxy resin composites have been widely used to prepare the basin-type insulators in gas-insulated switchgear (GIS). In recent years, air cavity defects became one of most common factors induce GIS faults. Therefore, development novel detection techniques for cavities is great importance. this study, multiple samples containing various submillimeter were prepared. Long pulse thermography (LPT) was employed detect composite, and data processing methods applied extract...
The microstructure and impact toughness in an ultra-high-strength casing were investigated, attempting to reveal the reason for fluctuations along terms of crystallography. morphological structures at head are lath bainite, while those end granular bainite bainite. exhibits a higher density high-angle grain boundaries dominated by block than end, showing inhomogeneous causing casing. resulted from weaker variant selection because its cooling rate end. Therefore, underlying lies varying...
Small-size Laves phase precipitates have the advantage of providing superior high-temperature properties to ferritic stainless steels. However, coarsening becomes inevitable during long-term service at elevated temperatures, which causes degradation strength and thermal fatigue resistance. In this study, precipitation behavior is elucidated in W-containing steels temperature range 800–1100 °C. preferentially precipitated grain boundaries were uniformly dispersed within grains after aging....
Carbon fiber-reinforced polymer (CFRP) is recognized as a promising anode material to prevent steel corrosion in reinforced concrete. However, the electrochemical performance of CFRP itself unclear. This paper focuses on understanding and mechanical properties an oxygen evolution environment by conducting accelerated polarization tests. Different amounts current density were applied tests with various test durations, feeding voltage potential measured. Afterwards, tensile carried out...
The mechanical and electrochemical performance of carbon fiber-reinforced polymer (CFRP) were investigated regarding a novel improvement in the load-carrying capacity durability reinforced concrete structures by adopting CFRP as both structural strengthener an anode impressed current cathodic protection (ICCP) system. aqueous pore solution which electrolytes available to cured structure. Accelerated polarization tests designed with different test durations various levels applied currents...
Polymer-based composites with excellent dielectric properties are essential for advanced energy storage applications. In this work, the [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) as a filler was incorporated into poly(vinylidene fluoride-co-hexafluoropropylene) (P(VDF-HFP)) composite to improve its performance. P(VDF-HFP) films varying PCBM concentrations were prepared via solution casting and their dielectric, storage, charge–discharge characterized. It found that doped could...
In order to achieve excellent heat resistance and corrosion resistance, high melting-point rare earth elements were added ferritic stainless steel. The effect of W Ce addition in steel on the 0.1 M NaOH solution was studied. Potentiodynamic polarisation curves indicated that W- Ce-containing samples had lower rate passive current density. electrochemical impedance spectroscopy measurements revealed W–Ce-containing higher values thicker films. Capacitance analysis semiconducting behaviour...
