PURPOSE: A manufacturing method of concrete using a superplasticizer combined with carbon amino silica black is provided to enhance compressive strength, tensile strength, and a coefficient of elasticity for concrete. CONSTITUTION: A manufacturing method of concrete using a superplasticizer combine with carbon amino silica black uses 0.5-10 wt% of a polycarboxylic acid-based high functional water reducing agent based on binders of concrete. The polycarboxylic acid-based high functional water reducing agent includes 0.1-30 wt% of carbon amino silica black. The silica mole fraction of the carbon amino silica black is 0.1-20 wt%. The replacement rate (W/B) of the concrete is 15-50%. The concrete includes 25-100 wt% of cement, 0-40 wt% of blast furnace slag powder, 0-25 wt% of fly ash, and 0-10 wt% silica fume.
