The invention relates to the technical field of preparation of supercapacitors and geopolymer concrete, and discloses a carbon nanotube fly ash composite material and a preparation method and application thereof. The carbon nanotube fly ash composite material comprises an acidified carbon nanotube fiber fabric and a fly ash compound attached to the acidified carbon nanotube fiber fabric, the fly ash compound contains a binding material, fine aggregate, an alkali activator and carbon fibers, and the binding material is a mixture of fly ash, slag and silica fume. The carbon nanotube and fly ash composite material has good strength, ductility and specific surface area, and the asymmetric supercapacitor prepared from the carbon nanotube and fly ash composite material is stable in performance, high in charge and discharge efficiency and large in energy density and power density, and can be applied to large-capacity energy storage aspects of residence, traffic, industrial application and the like. 本发明涉及超级电容器以及地聚合物混
