One of the most important and usable construction materials used in civil projects is concrete. High performance concrete (HPC) has more appropriate performance in consistency, compressive strength and durability respect comparing ordinary concrete. One of ways of improving physical features and specifications of concrete is improving the water physical specifications as one of main elements constituting the concrete. In recent decades, in countries like Russia and China, a new and advanced technology has been discussed called magnetic water. This water is passed a magnetic field with varying current intensity and as a result, its physical quality undergoes some changes. Due to these changes, the water molecular structure is altered and the number of molecules in a molecular community is reduced from 14 molecules to 5 or 6 and as a result, the surface tension of water is decreased. Using magnetic water in the concrete structure, in one hand, increases the consistency of concrete mixture and reduction of water to cement ratio and on the other hand, by facilitating the cement hydration process increases the concrete strength and durability.
