NOVELTY - Nano-graphene concrete material comprises 100 pts. wt. cement, 0.1-50 pts. wt. compact filling agent, 0.1-30 pts. wt. mineral admixture, 0.01-0.15 pts. wt. graphene oxide, 0.1-2.5 pts. wt. dispersant, 0.1-3 pts. wt. thixotropic agent, 0.1-1.5 pts. wt. accelerating agent, 0.1-2 pts. wt. thickening and water retaining agent, 0.01-0.1 pts. wt. antifoaming agent, and 0.1-2 pts. wt. fiber. USE - The material is useful for architectural 3 dimensional (3D) printing. ADVANTAGE - The method: can adjust the setting time of concrete material. The material: has better fluidity, high bonding strength, anti-leakage and high interlayer bonding strength, better printing accuracy, and has adjustable coagulation time; and can print high-precision building components. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the nano-graphene concrete material.
