A bibliometric analysis and comprehensive review of magnetized water effects on concrete properties

Abstract

This study is a critical review to assess the feasibility of using magnetic water to boost the overall performance of concrete. This is specifically conducted by evaluating the improvements of mechanical properties (split tensile strength, compressive strength, and flexural strength), cement particle water absorption, and cement hydration of concrete as a result of adding magnetic water if compared to concrete made with regular tap water. The benefits and associated challenges of utilising magnetic water in concrete are thoroughly discussed based on the most recent experimental and numerical studies published in the open literature between 2019 and 2023. According to the findings, the tensile strength, compressive strength, flexural strength, and electrical conductivity increase by 6.1%, 24.4%, 3.9%, and 0.5%, respectively, in concretes created with MW compared to regular tap water. Also, the magnetic field intensity of 1.3 Tesla yields the greatest improvement in the slump by 5–13 mm. However, the magnetic water shows the highest sorptivity at a magnetic field intensity of 0.9 Tesla. Also, using magnetic water makes concrete block pavers less absorbent of water and more resistant to assault by sulfuric acid. This review would encourage future research and widespread use of magnetic water in concrete production.
