Ecological slope protection brick taking slag and steel residue as main raw materials, and preparation method thereof

The invention provides an ecological slope protection brick taking slag and steel residue as main raw materials, and a preparation method thereof, wherein the ecological slope protection brick comprises the following raw materials by weight: 40-45 parts of slag, 40-45 parts of steel residue, 3-7 parts of an excitant and 9-11 parts of cement. Compared with the method in the prior art, the method ofthe invention has the following characteristics that the slag and the steel slag are used as the main raw materials, and the gypsum is used as the excitant, so that the cement consumption is reduced,wastes are turned into treasure, the environment is protected, the cost is greatly reduced, and the market prospect is wide. According to the invention, in the preparation process, the mixing and stirring speed is controlled, the macroscopic and microscopic dispersity of the material is improved, and the combination of cement particles and other materials is promoted, so that the mechanical property of the slope protectio
