Abstract
The use of magnetic water treatment as a technique for improving the properties of concrete is a relatively new area of research. The objective of this study was to investigate the effects of magnetic water treatment on the properties of Portland cement concrete. The study utilized a mix design consisting of Portland cement, fine and coarse aggregate, mineral additive (Fly Ash), chemical admixture (Superplasticizer) and water that was treated with magnetic field. In this research, the effect of magnetic water (MW), superplasticizer (SP) dose, fly ash (FA) percentage and W/B ratio were altered in order to examine the fresh and hardened properties of concrete plus non-destructive test results as well. The MW was obtained using a 1.4 Tesla magnetizer. The SP was added by 0%, 1%, 2% by weight of cement. the FA was replacing the cement by 0% to 20% by weight while the W/B was examined at 0.4, 0.45 and 0.5. The results showed that the use of magnetic water treatment improved the mechanical properties of the Portland cement concrete. The highest improvement was observed at a W/B = 0.4 employing magnetic water where the compressive strength increased by 18%, splitting tensile strength by 16% and flexural strength by 15%. The study found that the technique of magnetic water treatment improved workability of concrete mixture and resulted in reduction of water-cement ratio. The study concluded that the magnetic water treatment can be used as an effective technique for improving the mechanical properties and workability of Portland cement concrete.
