Abstract
Abstract This work investigates the sulfate and chloride resistance of cement composites (mortar and concrete) manufactured using electrolyzed water. Control and electrolyzed water-based cement composites were prepared using distilled water and 30 min electrolyzed water, respectively. These were exposed to 5% Na2SO4, 3.5% NaCl, and a combined mixture of 5% Na2SO4 and 3.5% NaCl solution for 200 days. Additionally, rebar reinforced control and electrolyzed water-based samples were exposed to ambient air and 5% NaCl solution for 180 days, and their corrosion potential was monitored. For control specimens, the results show compressive strength losses of 5, 12.4, and 6.1% when exposed to the above solutions, respectively, whilst for electrolyzed water-based specimens, the losses were reduced to 1, 10.1, and 3.4%, respectively. Statistical analysis of the potential values from the accelerated corrosion tests also show reduced corrosion (58 mV less negative potential) in rebar embedded in electrolyzed water-based specimen (−548 mV at 180 days) than in control specimen (−606 mV). Based on the spectral and microstructural analysis, the enhanced durability performance of electrolyzed water-based specimens is attributed to the lower ingress of deleterious agents through the less porous and compact microstructure of the hardened composites.

In the reported study, the performance of some generic and proprietary inhibitors in inhibiting corrosion of reinforcing steel in cracked and uncracked silica fume cement concrete beams was evaluated. Two types of concrete beams, uncracked and cracked, were prepared according to ASTM G109 and they were exposed to wetting and drying cycles of salty water. The performance of the selected inhibitors in decreasing reinforcement corrosion in the concrete beams was monitored by measuring the micro-cel...

Abstract This paper reviews the use of recycled aggregate (RA) that is collected from construction demolition waste in the production of concrete. The paper primarily focuses on the possibility of using RA in high performance concrete (HPC). By analytically reviewing previous work, this study reports the mechanical and physical properties of HPC prepared using RA. The study summarizes the results of workability, water absorption, dry density, compressive strength, tensile strength, and flexural ...

Abstract This study investigates the effect of surface corrosion on the pullout behavior of straight steel fibers embedded in ultra-high-performance concrete (UHPC). To this aim, straight steel fibers, either with or without surface corrosion, were utilized, and various corrosion degrees from 2% to 15% by weight were considered. To evaluate the implication of rust layer on the pullout behavior of corroded steel fibers from UHPC, both washed and unwashed conditions were considered. The surface ro...

Abstract The use of electrolyzed water is expected to be a unique alternative approach to early repair of structural concrete and step up the construction process. The present investigation reveals the effectiveness of electrolyzed water in controlling the physical and mechanical properties of cement mortar at the fresh and early hardened states. The mortar samples were made using distilled water and 30 min electrolyzed water to compare their properties. The effect of the electrolyzed water on t...

Abstract The effect of electrolyzed water in controlling the setting behavior of cement paste was investigated in this study. The distilled, as well as the 30 min electrolyzed water, was used to prepare the cement paste. Analyzing the results, the final setting time of control cement (CC) paste, as well as the 30 min electrolyzed water based cement (EC) paste, was measured to be 172 ± 5 min and 108 ± 4 min, respectively. The reduction of setting time is due to the quick hydration of cement clink...

The present article investigates the mechanism behind the sulfate attack of the Ordinary Portland Cement (OPC) and the Silica Fume (SF) based mortar exposed to the combined sulfate and chloride-rich solution. In this study, the control mortar sample was fabricated using OPC. Additionally, the silica fume based mortar composites were fabricated using SF replacing the 5, 10, and 15% of OPC. The 28 days cured control and silica fume based mortar samples were exposed to a sodium sulfate (5%) solutio...

Abstract Desulfurization, known as the removal of sulfur from oil, is extremely important in the petroleum processing industry and in the environmental protection. Several oil-upgrading processes such as desulfurization and catalysts such as alumina loaded with molybdenum have been proposed to deal with the problem of removing sulfur-containing compounds from light oil. Thus, several parameters are required to be experimentally optimized which demands a lot of work including reagents. Advanced m...

We evaluated the performance of 3 different left ventricular leads (LV) for resynchronization therapy: bipolar (BL), quadripolar (QL) and active fixation leads (AFL). We enrolled 290 consecutive CRTD candidates implanted with BL (n = 136) or QL (n = 97) or AFL (n = 57). Over a minimum 10 months follow-up, we assessed: (a) composite technical endpoint (TE) (phrenic nerve stimulation at 8 V@0.4 ms, safety margin between myocardial and phrenic threshold 15%). Baseline characteristics of the 3 group...

The efficiency of generic and proprietary corrosion inhibitors (based on nitrite, amine carboxylate or amino alcohol) in corrosion mitigation of carbon steel, which is exposed to concrete solutions with different amounts of chloride as well as sulfate, was studied. The corrosion protection provided by the selected corrosion inhibitors was investigated by performing a potentiodynamic polarization study. In addition, the surface morphological properties of carbon steel samples exposed to the elect...
