Preparation method of all-solid waste concrete filled steel tube containing waste incineration fly ash

The invention discloses a preparation method of an all-solid-waste concrete filled steel tube containing waste incineration fly ash. The preparation method comprises the steps of S1, preparing coarse aggregate and steel slag particles with the particle size being less than 5mm; S2, preparing fine aggregate and molybdenum tailing particles with the particle size of 0.038 mm to 0.074 mm; S3, grinding the waste incineration fly ash, the steel slag particles smaller than 5 mm and molybdenum tailing particles of 0.038 mm-0. 074 mm; S4, grinding the refining slag and the vanadium-titanium slag; S5, grinding phosphogypsum; S6, mixing the powder materials in S3, S4 and S5 to obtain a composite cementing material; and S7, mixing the composite cementing material, the fine aggregate, the coarse aggregate, the bean curd wastewater and the water reducing agent, stirring, forming and curing to obtain the concrete product. According to the preparation method, the problem that harmlessness, reduction and recycling of the was
