The effect of magnetic water on strength parameters of concrete

Abstract

A machine for magnetic water treatment is designed and its application on the ions contained in water has been investigated to examine the effect of magnetic water on concrete parameters. Strength parameters of concrete have been studied for >104 concrete samples including the nonmagnetic samples (made by ordinary water) and magnetic samples (made by magnetic water) with slump and compressive strength experiments. Based on slump experiments, magnetic samples were 7 cm more than nonmagnetic group and the average compressive strength of samples made by magnetic water was 23% more than that of samples made by ordinary water. The experimental results show the advantages of magnetic samples in concrete industry because of increase in plasticity, the efficiency and quality of concrete boosts in comparison with nonmagnetic samples. © Medwell Journals, 2011.
