Water is a vital constituent that controls much of concrete properties such as strength and workability. Water is added to concrete in the form of a liquid at ambient temperature. However, it is occasionally added in the form of hot water in freezing conditions or in the form of ice/chilled water in hot weathering conditions. Recently, work has been conducted to magnetize water to adequate level before being incorporated in concrete. Indications show that some improvements can occur to concrete made with magnetized water. However, there is scarcity of data as to how such magnetized water can influence the properties of concrete on the short and long term properties.
This study is an attempt to improve the understanding of the impact of magnetized water on fresh, hardened and long term concrete properties. Mixtures were made with water to cement ratio of 0.34 and 0.45 without admixtures, with plasticizers and superplasticizers. Water was added with 0,0.1, 0.2, 0.3 and 0.4 Tesla levels of magnetization. A group of mixtures were made with freshly magnetized water while another was made after magnetized water was stored for three days. Fresh tests comprise compressive strength, modulus of rupture, water permeability, rapid chloride permeability, chemical soundness and abrasion resistance tests.
Results reveal that -on the whole- magnetized water introduce enhancement to concrete workability although such enhancements vary according to mix parameters.
