The invention discloses a self-leveling mortar prepared from building wastes. The self-leveling mortar is prepared from, by weight, 10-20 parts of cement, 15-25 parts of recycled fine aggregates withthe particle diameter being 0-2.36 mm, 30-40 parts of recycled fine aggregates with the particle size being 70-140 meshes, 15-20 parts of recycled powder with the particle size being 300-500 meshes, 7-10 parts of recycled ultrafine powder with the particle size being more than 500 meshes, 0.5-1 part of an active exciting agent, 0.1-0.2 part of a dispersant, 0.1-0.2 part of a water repellent and 1.5-2.0 parts of an anti-break admixture. The recycled fine aggregates, the recycled powder and the recycled ultrafine powder are prepared by crushing and screening brick concrete building wastes. The invention also discloses a preparation method of the mortar. The mortar prepared in the invention has the advantages of light weight, good fluidity, recycling of building material solid wastes, and reduction of the use of buil
