Assessing the properties of concrete produced with magnetized water at different magnetic field intensities

The civil engineering network continues to advance the use of high-performance, environmentally friendly building materials. Water also plays a crucial role in concrete quality, as it helps resist corrosion and contributes to overall strength. Therefore, water should be salt-free and have characteristics comparable to potable water. Addressing the dual global challenges of concrete durability and the cement industry’s CO₂ emissions requires innovative solutions. Magnetic water emerges as a promising non-chemical and sustainable additive. In contrast to the well-documented benefits at lower fields, outcomes at higher field strengths (> 1.5 Tesla (T)) are inconsistent. An attempt was made to investigate the performance of M20 grade concrete when mixed with magnetic water at different intensity levels (0.5 T, 1 T, 1.5 T, & 1.8 T). This technology utilizes Magnetic Field Treated Water, which restructures its molecules to enhance percolation into cementitious matrices. The enhanced permeability subsequently accelerates the hydration kinetics and efficiency. This study investigates the performance of MW on the mechanical properties of a concrete mix with different intensity levels. Slump workability increased by 51% at 1.8 T. The concrete specimens exhibited an 18–23% increase in compressive strength and an 8–10% increase in split tensile strength. Characterization methods such as thermogravimetric analysis (TG), X-ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Energy-Dispersive X-ray Spectroscopy (EDX) were employed for NWC and optimized MWC (1.8 T) to quantify the hydrated products.
