Description

Concrete is the most widely used man-made building material on the planet. The reaction of cement with water results in hydration products, which glue the reacting cement particles together to form a hardened cement paste. So water is very essential for concrete to gain the required strength. IS code says that the water which is potable is suitable for mixing in concrete. This paper finds a new technology called magnetization of water. As per this technology, by passing water through a magnetic field, some of its physical properties tends to change and, as a result of such changes, the cluster size in water molecules breaks down due to decrease in the bond angle between the hydrogen atoms, which causes decrease in the hardness of water, with an improvement in the workability and strength of concrete when compared to use of potable water in concrete. As water is becoming scarce to meet the daily domestic needs of the living beings, use of portable water for concrete mix should be substituted by an alternate source of water. Hence this paper also made an attempt to use the magnetized waste water (MWW) instead of portable water for making concrete. This paper deals with the experimental study on the mechanical properties of M25 grade concrete with the normal water (NW), magnetic water (MW), and magnetic waste water (MWW). The mix design obtained is 1:1.8:2.18. In order to analyze the mechanical properties such as Compressive strength, Flexural strength, and Split tensile strength, the samples were casted and tested for different periods of curing like 7 days, 14 days and 28 days. The tests showed encouraging results and one can easily replace normal water with magnetic water for mixing of concrete.
