Magnetic gathering type pavement material for dynamic induction charging of automobile and preparation method of magnetic gathering type pavement material

The invention relates to a magnetism gathering type pavement material for automobile dynamic induction charging and a preparation method. The magnetism gathering type pavement material comprises the following ingredients: geopolymer slurry and a magnetizing agent, wherein the geopolymer slurry comprises the following components: an alkaline activator, water, fly ash, granulated blast furnace slag, red mud, metakaolin, coconut ash and other alkali active materials, wherein the fly ash is composed of silica tetrahedron and alumina tetrahedron and has silicon-aluminum activity, and the molar ratio of SiO2 to Al2O3 in the components contained in the geopolymer slurry is 3.0-5.6. The dynamic induction charging pavement system can effectively gather magnetic fields, reduces magnetic leakage, further reduces energy loss in the induction charging process, solves the problem that an existing dynamic induction charging pavement system is low in charging efficiency, and has the advantages of being excellent in electroma
