EFFECT OF MAGNETIC STRUCTURED WATER ON THE PROPERTIES OF POLYPROPYLENE FIBRE REINFORCED CONCRETE

Abstract

This experimental investigation shows the effect of magnetic structured water on the strength properties
of magnetic water concrete with addition of polypropylene fibre and comparing the test results with conventional
concrete with and without poly propylene fibres. Cubes and cylinders were cast by using normal water and magnetic
structured water of different intensities (viz; 0.2T, 0.4T, 0.6T) and various percentages of polypropylene fibres (viz 0%,
0.2%, 0.4%, 0.6%, 0.8%, and 1.0%). Compression and split tensile tests were done on cubes and cylinders to obtain the
optimum dosage of fibres. With the combination of fibre with normal water, the maximum compressive strength
40.89Mpa was obtained at 0.8% of fibre. It was found that the maximum compressive strength of 48.28MPa was
obtained with a combination of 0.6%poly propylene fibre and magnetic structure water of intensity 0.6Tesla which is
almost nearer to 50MPa.Whereas the maximum split tensile strength obtained with different combinations of
polypropylene fibre, normal water and magnetic water cylinders were was found to be 2.83MPa was obtained with a
combination of 0.8% polypropylene fibres and potable water. The maximum split tensile strength of 4.41MPa was
obtained with a combination of 0.6%polypropylene fibres and magnetic structured water of intensity 0.6Tesla.
