Abstract
mail: - E Abstract This research investigates the influence of magnetic water on compressive strength and workability (consistence) of concrete. Results show that the compressive strength of concrete samples prepared with magnetic water increases 10-20% more than that of the tap water samples. In the present study, increasing in compressive strength of concrete is achieved when the magnetic strength of water is 1.2 T, and velocity of water current that passes through magnetic field is of 0.71 m/s. It is also found that magnetic water improves the workability (consistency) of fresh concrete.

Much research in recent years has been devoted to establishing the fundamental and engineering properties of high-strength concretes, as well as the engineering characteristics of structural members made with the material [1,2].Increasing the compressive strength of concrete is an aim which most researchers are looking for, using various methods to do so, as the use of fiber reinforcement in a concrete mixture [3] to increase concrete strength
3.4: Mix proportions: In the present study, to find the effect of current velocity and time treatment of water on the compressive strength and consistency of concrete, to find the optimum characteristic of water treatment, 7-type of mixes were prepared, these mixes are (N, M1, M2, M3, M4, M5, and M6), mix-N is the normal concrete which is prepared with normal water, (M1, M2, M3, M4, M5, and M6) are the normal concrete prepared with magnetic water which is prepared by exposing water to magnetic field strength about
Summary
More than one hundred relevant articles and reports are available in the open literature, so clearly magnetic water treatment has received some attention from the scientific community. The characteristic relaxation time of hydrogen bonds between water molecules is estimated to be too fast and the applied magnetic field strengths too small for any such lasting effects, so it is unlikely that magnetic water treatment affects water molecules (Lipus et al [23]). Among those who report some type of direct magnetic-water-treatment effect, a consensus seems to be emerging that the effect results from the interaction of the applied magnetic field with surface charges of suspended particles (Donaldson [24]; Lipus et al [23]). The magnitude of the change in particle charge increased as the strength of the applied magnetic field increased
