The invention relates to the building field and particularly relates to concrete doped with waste bricks and recycled coarse aggregates and preparation method of concrete. The concrete is characterized by being prepared from the following raw materials in parts by weight: 1-1.6 parts of a cementing material, 1-1.7 parts of fine aggregates and 1.2-2.5 parts of recycled coarse aggregates. According to the concrete, the resource consumption in the construction process of buildings is greatly reduced, the construction waste is processed, and the environmental burden is alleviated.
