NOVELTY - High strength large volume concrete comprises 384-424 pts. wt. cement, 55-61 pts. wt. fly ash, 44-48.8 pts. wt. silicon powder, 33-36.6 pts. wt. steel slag powder, 27.5-30.5 pts. wt. boron nitride powder, 8.3-11.0 pts. wt. graphene oxide sheet powder, 544-648 pts. wt. sand, 1010-1105 pts. wt. crushed stone, 1.4-1.6 pts. wt. high-strength polyvinyl alcohol fiber, 11-12.2 pts. wt. polycarboxylic acid-based water reducing agent, 5.5- 6.1 pts. wt. dispersion activator, 55.0-97.6 pts. wt. modified graphene oxide dispersion and 91.5-126.5 pts. wt. water. USE - High strength large volume concrete. ADVANTAGE - The high strength large volume concrete has water permeability, anti-chloride ion permeability, freezing resistance, carbonization resistance and has good social and economic benefits. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high strength large volume concrete, which involves: (A) adding 1010-1105 pts. wt. gravel, 544-648 pts. wt. sand, 44-48.8 pts. wt. silicon powder, 27.5-30.5 pts. wt. boron nitride powder and 1.4-1.6 pts. wt. high strength polyvinyl alcohol fiber in the mixer-make and fully mixing; (B) sequentially adding 384-424 pts. wt. cement, 55-61 pts. wt. fly ash, 33-36.6 pts. wt. steel slag powder and graphene oxide sheets, 8.3-11.0 pts. wt. the powder and stirring uniformly mixed; (C) adding 5.5-6.1 pts. wt. the dispersing activator, 11-12.2 pts. wt. the polycarboxylic acid type water reducing agent, 55-97.6 pts. wt. graphene dispersion and 91.5-126.5 pts. wt. water and stirring to obtain a mixture; and (D) slowly adding prepared mixture in under stirring to obtain desired product.
