A nanometer reinforcing method belongs to the technical field of multipurpose use of building wastes and manufacture of building materials. The nanometer reinforcing method of completely-regenerative concrete aggregate mainly comprises the steps of: immersing regenerative coarse aggregate in a nanometer calcium carbonate solution for 30-60 minutes to perform aggregate reinforcement; and mixing the concrete by completely replacing the natural coarse aggregate with the reinforced aggregate. The reinforcing method which combines a reinforcing process with a mixing process effectively reduces procedures and cost, saves time and is suitable for engineering application. The nanometer reinforcing method of completely-regenerative concrete aggregate is mainly characterized in that: the mixing process is changed and nanoparticles are introduced; the micro-fissure and open pores of the regenerative aggregate are filled up with nanometer materials due to the fine particles and high penetrability , thus the strength of t
