NOVELTY - A regenerating preparation method of carbon fiber composite graphene-reinforced concrete comprises preparing raw materials comprising cement, sand, coarse aggregate, water, nanomaterial, water reducing agent and fiber material; adding nanomaterial, water reducing agent and water, performing ultrasonic dispersion for 30-60 minutes to obtain suspension; mixing cement, fiber material, sand and aggregate in mixer, stirring for 3-4 minutes, stirring uniformly, and obtaining mixture; and adding prepared suspension into the mixture, and stirring for 3-5 minutes. USE - Regenerating preparation method of carbon fiber composite graphene-reinforced concrete. ADVANTAGE - The prepared concrete is more compact, and has improved rupture strength and compressive strength. DETAILED DESCRIPTION - Regenerating preparation method of carbon fiber composite graphene-reinforced concrete comprises (A) preparing raw materials comprising cement, sand, coarse aggregate, water, nanomaterial, water reducing agent and fiber material at wt. ratio of 1:1.4-1.6:2.6-3:0.28-0.32:0.0001-0.0005:0.01-0.05:0.012-0.016; (B) adding nanomaterial, water reducing agent and water, performing ultrasonic dispersion for 30-60 minutes to obtain suspension; (C) mixing cement, fiber material, sand and aggregate in mixer, stirring for 3-4 minutes, stirring uniformly, and obtaining mixture; and (D) adding prepared suspension into the mixture, and stirring for 3-5 minutes to obtain carbon fiber composite graphene-reinforced recycled concrete. The nanomaterial is graphene having grain diameter of 0.6-1 nm. The fiber material is nanocarbon fiber whose average diameter is 150 nm and length is 30-100 mu m.
