Effect of Magnetic treatment technology on the (workability and compressive strength) of High- Strength Concrete

Abstract

The magnetic technique is considered one of the methods that improve the mechanical properties of concrete, either by using magnetic water to mix concrete mixture or by magnetizing mix itself. In this research, the effect of a magnetic field on features of high-strength concrete (workability and compressive strength) was studied. Two mixes were used, both with 70MPa but one with ordinary lab water and the other with magnetic water. Both of these mixes were exposed to the magnetic field bay passing them through three devices that had different magnetic units three, four, and five, each unit with 3000 Gauss intensity. When the magnetic water was used instead of ordinary water, the slump test value was raised to 19% from the reference mix. When the mixes are exposed to a magnetic field, there is no increment in a slump. Compressive strength was raised to 7% when using the tube with five magnetic units to mix without magnetic water.
