▎ 摘 要
NOVELTY - Concrete comprises 300-500 pts. wt. cement, 150-300 pts. wt. fine sand, 100-200 pts. wt. medium coarse sand, 80-110 pts. wt. mineral powder, 1000-1150 pts. wt. crushed stone, 0.6-1.2 pts. wt. concrete fiber, 5-15 pts. wt. graphene oxide, 5-10 pts. wt. water reducing agent, 4-8 pts. wt. dispersing agent, 4-8 pts. wt. retarder and 120-200 pts. wt. water. The cement is Portland cement. The crushed stone includes first gradient crushed (particle size 5-10 mm), second gradient crushed stone (particle size 10-16 mm), and third gradient crushed stone (particle size 16-20 mm). The water reducing agent is polycarboxylic acid water reducing agent. The dispersant includes calcium lignosulfonate, sodium lignosulfonate, gallic acid, polyvinylpyrrolidone and/or sodium alginate. USE - The concrete is useful for construction. ADVANTAGE - The concrete is graphene oxide modified. The method solves technical problems of poor durability and low fluidity of traditional cement concrete by optimizing components of graphene oxide modified cement concrete. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing concrete.
