This paper presents the effect of magnetic structured water on the properties of magnetic water
concrete of M25 grade. Cubes of standard size 150mmx150mmx150mm and cylinders of diameter 150mm and height
300mm were cast with magnetic structured water subjected to constant magnetic fields (viz., 0.2T, 0.4T, 0.6T) for 24
hours and 12 hours and cured with potable water, magnetic structured water and also under constant magnetic field.
The workability, compressive strength and split tensile strength were determined and compared with conventional
concrete. It was found that the compressive strength of cubes cast with 0.6T magnetic water subjected to 24 hours of
magnetic field and cured under constant magnetic field of intensity at 0.6T was found to be 58.36 MPa; which was
2.86% higher than the highest compressive strength (56.68MPa) of cubes cast with 0.6T magnetic structured water
subjected to 24 hours of magnetic field and cured with magnetic structured water of intensity 0.6T. Which is again
13.7% higher than the compressive strength (50.356MPa) of cubes cast with 0.6T magnetic structured water subjected
to 24 hours of magnetic field and cured with potable water. Which is again 31.45% higher than the compressive
strength (40MPa) of conventional concrete. Whereas the split tensile strength of cylinders cubes cast with 0.6T
magnetic water subjected to 24 hours of magnetic field and cured under constant magnetic field of intensity at 0.6T
was found to be 8.001MPa which was 3% higher than the highest split tensile strength (7.77Mpa) of cylinders cast
with 0.6T magnetic structured water subjected to 24 hours of magnetic field and cured with magnetic structured water
of intensity 0.6T. Which is again 9.7% higher than the split tensile strength (7.22MPa) of cylinders cast with 0.6T
magnetic structured water subjected to 24 hours of magnetic field and cured with potable water. Which is again 37.5%
higher than the split tensile strength (5MPa) of conventional concrete.
