Improvement Concrete Mechanical Properties Using Static Magnetic Field Treatment

In the current study, a new technology of magnetized concrete prepared using static magnetic field treatment is investigated. Methodology of the current proposal is to manipulate the placing process of the fresh concrete samples, while maintaining the same materials with the same configurations. The purpose of this study is to determine the effect of different magnetic treatments to the fresh and hard concrete characteristics. Five set of samples are planned, one set using traditional process without magnetic treatment, while the other four sets are treated with 0.04, 0.08, 0.12 and 0.15T (Tesla), respectively. The results showed that directly applying the magnetic field on concrete increases the compressive strength about (3-15%) and it simultaneously improves the flow capacity (workability) for the fresh concrete corresponding to some certain treatment ranges. Unlikely, the study showed that the magnetic treatments could be detrimental for some other range of treatments especially at long-term performance. The results of this study could be a first step towards devolving new generation of smart structures through application of magnetic field treatment to the fresh concrete.
