The invention discloses a construction waste recycling technology. The technology comprises an aggregate production technology, a premixed mortar production technology, a building block production technology, and a wallboard production technology. The construction wastes are graded, grinded, and sieved to produce aggregate that can replace the natural sand and stones. Part of the aggregate can be used to produce premixed mortar, cement mixed material, and concrete products. The residual aggregate is packed as commercial aggregate for sale, and can be used in concrete mixing plants, premixed mortar plants, and road structural foundation backfilling. The produced powder can be used to product concrete products, and the produced soil can be directly used as greening soil. The construction wastes are graded, removed, or grinded, and then subjected to a series of technological procedures, so that the wastes are converted into renewable resources and reutilized, and the economic profit is prominent. The sprayed dusts and sands which cause severe environmental pollution during the transportation and storage process are avoided. Solved is the problem that plants cannot grow on the soil that is used to bury construction wastes.
