Magnetizable concrete composite materisl for riad embedded wireless power transfer pads

In this paper, MAGnetizable CONcrete (MagCon) composite materials are introduced and studied thoroughly. MagCon material is obtained by mixing cement with a magnetic material, for example, powdered ferrite or magnetite with different aggregate ratios and sizes, and optionally adding other aggregates to the mixture. Effective relative permeability (μr,eff) of MagCon is evaluated as a function of volumetric ratio of the magnetic material in the mixture. Furthermore, the effect of aggregate size of the magnetic materials is examined and the core losses of MagCon are analyzed. Compressive strength of the new material is also discussed. MagCon can be used in the core structure of road-embedded Wireless Power Transfer (WPT) pads for Electric Vehicle (EV) charging applications. MagCon has the benefit of significant design flexibility and reduced cost
