Effect of Magnetized Water on Working Performance of Cement Mortar

Compared with common drinking water, magnetized water seems to have the potential to save water for concrete production. The main purpose of this paper is to combine theoretical analysis and experimental verification of multiple sets of comparative tests to study the effect of magnetized water on the performance of cement mortar. This paper starts with the structure of water and the mechanism of hydrogen bond formation, clarifies the activation mechanism of magnetized water, and combines the properties of magnetic field to activate water to explain the mechanism of magnetized water enhances the performance of cement mortar. Through a cross-contrast test that combines four magnetic field strengths and three mortar strength grades, it is found that when cement mortar is mixed with magnetized water, the compressive strength increases by about 20% compared with ordinary water mixing, and the maximum increase can be as high as 25.3 %. Also, the additional strength obtained through the use of magnetized water meets the need to reduce the amount of cement in mortar, and at least 10% of cement can be saved when the design strength of the reference mix proportion is met.
