Abstract

Magnetic water changes the electron configuration of the ions, followed by significant changes in hardness, electrical conductivity of surface tension and other physical and chemical properties of water. These changes in the cement reaction create a situation that has a significant impact on the improvement of the properties of concrete in fresh and hardened states and is therefore of concern to the researchers. One of the basic characteristics of Magnetic water, which is very important in the production of concrete, is the dependence of water on particles and colloidal solutions. When water is mixed with cement, a colloidal solution of cement is obtained, which if the water magnetic is used, the particles of the cement are surrounded by a single molecular layer of water with a lower density. This phenomenon makes it possible to reduce the amount of water used in the mixing of concrete, which will have a lot of benefits in concrete. Magnetization of water increases the hydration of negative ions, which damages the crystalline structure of the water. This paper studies the researches on Magnetic water and its effect on the Mechanical properties of lightweight concrete has been analyzed. The most influence of Magnetic water on the Mechanical properties of lightweight concrete has been obtained at the intensity of the magnetic field of 1 Tesla. The highest workability of cement paste made with Magnetic water was obtained by rotation of 65 minutes of water in a magnetic field with intensity of 1 Tesla. The most effective magnetic field intensity is achieved in 1 Tesla for magnetic field.
