Abstract
Magnetic water (MW) has recently gained popularity in concrete mix design due to its ability to reduce the percentage of cement used while improving concrete properties. This method also lowers carbon dioxide emissions associated with cement manufacturing, providing environmental benefits. In this study, two magnetic devices, one operating at 1.5 Tesla and the other at 0.9 Tesla, were used to treat water for 60 minutes using four different methods. The properties of both tap water (TW) and MW, including temperature, pH, and total dissolved solids (TDS), were measured. Additionally, the workability of the mixtures was assessed using the slump cone test for TW and the four MW mixes. For compressive strength testing, cubes with a 100 mm side length were utilized. The results showed that magnetizing TW increased its temperature, pH, and TDS. There was also a slight increase in slump values, and the compressive strength improved significantly: by 28%, 24%, 59%, and 44% for the 7-day strength measurements and by 13%, 11%, 25%, and 22% for the 28-day strength measurements, respectively. The third treatment method, using 1.5 Tesla followed by 0.9 Tesla, produced the highest values for water properties, slump, and compressive strength.
