The invention relates to a cementing material containing waste incineration fly ash, steel slag and mineral slag, and a preparation method and an application thereof. The cementing material containingwaste incineration fly ash, steel slag and mineral slag mainly comprises, by weight, 0-60 parts of S95 slag, 0-60 parts of high-aluminum steel slag, 20-40 parts of the waste incineration fly ash and7-13 parts of desulfurized gypsum. A ratio of the cementing material to aggregate in the concrete or a filing material is 1:4 to 1:8, and the concentration is 77%. A large amount of the waste incineration fly ash is added, and the cementing material has good industrially-applied compressive strength without adding additives such as an excitant and an early strength agent, so the cementing materialcan be used as a cementing material of concrete, can also be used as a mining filling material, and is a good substitute of cement.
