NOVELTY - Proportioning method of using regenerated fine aggregate to configure dry powder mortar involves: (A) selecting waste block concrete and granite waste for crushing, sieving using a 4 mm square-hole sieve, screening mortar, and adding coal-fired slag, mixing and stirring to obtain mortar aggregate; (B) obtaining biomass ash after burning biomass fuel, grinding for 20 minutes, and sieving; (C) accurately weighing the mortar aggregate, cement, the biomass ash, fly ash, desulfurized ash and gel material, mixing, adding water to a mixer to mix for 1-2 minutes, adding cement reinforcing agent, and stirring; (D) dissolving graphene oxide in deionized water, treating using an ultrasonic material disperser, starting the disperser for 3 seconds and then stopping for 5 seconds, and circulating for 10 minutes to form a brown solution; and (E) dissolving water reducing agent in water, adding to the mixer, adding graphene oxide solution, and stirring for 180 minutes. USE - Proportioning method of using regenerated fine aggregate to configure dry powder mortar used for building. ADVANTAGE - The method provides dry powder mortar that has excellent hydration speed of cement and fly ash system, and increases the strength of the mortar mixed with desulfurized ash better than that of the mortar without mixing.
