Enhancing Concrete Performance: A Comprehensive Review of Magnetic‐Field Treated Water Mixtures

The quality of mixing water significantly impacts cement hydration, which in turn strongly influences the properties of the resulting concrete mix. In pursuit of more sustainable concrete, researchers have explored various techniques to enhance hydration mechanisms and improve concrete performance. One emerging technology is implementing magnetic field‐treated water (MFTW) to enhance the properties of concrete. Compared to other methods for enhancing concrete properties, such as the use of chemical admixtures or specialized aggregates, magnetic water (MW) presents a more cost‐effective solution. The equipment needed for magnetic treatment is relatively inexpensive and readily available. In modern construction, MW is increasingly recognized for its significant contribution to enhancing the physicochemical properties of cementitious materials. MW has been shown to positively influence the hydration kinetics of cement, leading to a denser and more refined microstructure. This paper presents a comprehensive overview of the influence of the magnetizing process on the structure of water molecules, including modification in hydrogen bonding, cluster size, and bond angles. Additionally, this paper reviews the comprehensive research on the influence of MFTW on cementitious materials, specifically focusing on fresh properties like workability and setting time, mechanical properties—such as compressive, flexural, and split tensile strength—and durability characteristics including permeability, water absorption, sorptivity, early‐age shrinkage cracking, rapid chloride permeability (RCP), resistance due to abrasion, and resistance to sulfate attack. This study also highlights key factors influencing water magnetization, including magnetic pole configuration, field intensity, exposure time, and post‐magnetization storage duration. The overall findings revealed that using MFTW significantly improves the strength, durability, and flowability of cementitious materials, possibly due to its effects on hydration and microstructure development.
