Effect of Magnetic Water on Properties of Fresh and Hardened Concrete

Abstract

This study involves the investigation of influence of magnetic water on the workability and compressive strength of fresh and hardened concrete. “The water is initially magnetized with the help of 0.5 hp motor having a 1 and 3T magnets at its inlet pipe. Concrete samples are then prepared and cured with magnetic water and normal water in four main different cases. About 36 concrete and mortar cubes are casted and tested for 7, 14 and 28 days.” Results show that the compressive strength of concrete samples mixed with magnetic water is higher than those prepared with normal water. The compressive strength of concrete samples mixed with magnetic water at a magnetic strength of 1T increases by 10-20% more than that of normal water”. Also, the consistency of fresh concrete is improved in case of magnetic water than that of normal water.
