▎ 摘 要
NOVELTY - Environmentally friendly graphene oxide modified super high-rise concrete, comprises 945.86-962.40 pts. wt. gel material, 80-120 pts. wt. steel fiber, water, quartz sand, graphene oxide and polycarboxylic acid superplasticizer. The mass ratio of the water to the gelling material is 0.16. The mass ratio of the quartz sand to the cement material is 1.3. The mass of the polycarboxylic acid high-grade water reducer powder is 0.3% of the mass of the gel material. The gel material comprises 394.60-401.50 pts. wt. cement, 156.66-159.40 pts. wt. silica ash, 313.31-318.79 pts. wt. fly ash, and 81.29-82.71 pts. wt. slag powder. The mass of graphene oxide is 0.01-0.03% of the mass of cement. USE - Used as environmentally friendly graphene oxide modified super high-rise concrete. ADVANTAGE - The concrete has good concrete compression ratio and toughness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the concrete, comprising (i) preparing graphene oxide solution, (ii) mixing graphene oxide solution with the water at room temperature, mixing evenly at a speed of 2500-3000 revolutions/minute, mixing with polycarboxylic acid high-performance water-reducing agent, and adjusting the pH to neutral with sodium hydroxide to obtain an intermediate solution, (iii) taking quartz sand and pouring into the mixer, dry mixing for 1 minutes, adding gelling material and dry mixing for 1 minutes, adding the intermediate solution into the stirring pot and stirring wet for 2 minutes, adding the remaining amount of water and stirring for 2 minutes, adding steel fiber and stirring for 3 minutes, pouring into the mold and vibrating for 90 seconds, and (iv) covering the protective film after vibrating, and removing the mold after 24 hours of standard curing, where then increase the temperature to 10 degrees C/h to 90 degrees C for 24 hours, and cooling to 10 degrees C/h to room temperature, and finally standard curing to the age of detection.
