Abstract
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 the performance of mortar was evaluated by analyzing setting times, flowability, dry and wet bulk density, apparent porosity, water absorption, and mechanical strengths such as compressive and flexural strength. Analyzing the results critically, it is demonstrated that the use of electrolyzed water sets the cement faster (reduces initial and final setting time by 41 min and 64 min, respectively) and shows higher compressive (17, 16, and 13%) and flexural (19, 12, and 10%) strengths than that of the normal distilled water-based mortar at the early ages of curing (1, 3, and 7 days of curing, respectively). Finally, based on the microstructure analysis and X-ray diffraction, a plausible mechanistic model is designed to elucidate the overall performances of the electrolyzed water-based mortar.

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...

Abstract Synthetic plastics are typically discarded, thus causing environmental pollution. Plastic wastes are recycled as fiber in concrete to solve this problem. In this study, synthetic fibers in a concrete matrix were investigated through compressive strength, splitting tensile, fracture energy, and flexural beam tests. The results show that an increase in fiber content improves the tensile strength of the concrete matrix. A high fiber content results in a substantial amount of fibers crossin...

The paper presents the compressive strength distribution pattern of the hydrogen-rich water based cement mortar. In this study, the mortar samples were fabricated using different concentrations of hydrogen-rich water (0.2-0.5 ppm). The performance of hydrogenrich water was evaluated measuring the setting time and the compressive strength of the mortar samples. Subsequently, the strength data were statistically analyzed using the Weibull distribution model in the 37% and the 95% confidence level ...

Abstract This paper presents a study on alkali activated cement (AAC) mortar produced with waste soda-lime-silica glass. The waste glass was used simultaneously as a precursor and fine aggregates in the alkali activated fly ash-slag mortar. The influences of waste glass in cullet and powder forms on workability, compressive and flexural strengths, fire resistance of the AAC mortar were investigated. The experimental results showed that the workability was gradually increased as the replacement l...

Abstract Utilization of the sewage sludge ash in fabricating the construction material would be an effective alternative approach under the sludge management scheme other than landfilling. The present investigation deals with the utilization of the recycled sewage sludge ash (SSA) combined with the quicklime (QL) and blast furnace slag (BFS) as a cementitious material in controlling the physical and mechanical performances of mortar. The mortar samples were prepared using the different amount of...

Abstract The present article illustrates the acid and sulfate resistance performance of control (CM) and the hydrogen-rich water-based mortar (HM) samples. The 28 days cured CM and HM samples were exposed to 5% HCl, 5% HNO 3 , and 5% sodium sulfate solutions for 30, 60, 90, 120, 150, and 180 days to evaluate their acid and sulfate resistance performances. The impact of acid and sulfate attack was evaluated measuring the weight and compressive strength loss of mortar samples in the different expo...

Abstract Controlled low-strength material (CLSM) is a self-compacting, flowable, and low-strength construction material that is used widely in variety construction applications. The present study evaluates the properties of CLSM that was prepared using a mixture of class-F fly ash (FA) and ground granulated blast-furnace slag (GGBFS) with the addition of three different ratios (0%, 10%, and 20% as calculated by combined FA and GGBFS weight) of waste water treatment sludge (WTS). A sodium hydroxi...
