NOVELTY - A graphene oxide concrete comprises 115-415 pts. wt. cement, 30-50 pts. wt. coal ash, 50-90 pts. wt. mineral powder, 940-1070 pts. wt. stone, 720-1040 pts. wt. sand, 155-190 pts. wt. water, and 4.15-11.7 pts. wt. graphene enhancer. USE - A graphene oxide concrete. ADVANTAGE - The concrete has improved strength as much as 30-46%, durability and water resistance capability. DETAILED DESCRIPTION - A graphene oxide concrete comprises 115-415 pts. wt. cement, 30-50 pts. wt. coal ash, 50-90 pts. wt. mineral powder, 940-1070 pts. wt. stone, 720-1040 pts. wt. sand, 155-190 pts. wt. water, and 4.15-11.7 pts. wt. graphene enhancer. The graphene enhancer comprises 10-14 wt.% water reducing component, 12-18 wt.% slump retaining component, 3.2-3.6 wt.% sodium gluconate, 8-12 wt.% calcium oxide, 0.4-0.6 wt.% stabilizer, and 51-66 wt.% deionized water. The water reducing component comprises 30-35 wt.% methyl alkenyl polyoxyethylene ether, 3-4 wt.% acrylic acid, and 61-67 wt.% deionized water. The slump retaining component comprises 25-30 pts. wt. allyl polyoxyethylene ether, 10-15 pts. wt. maleic anhydride, 1-3 pts. wt. acrylic acid, 5-8 pts. wt. diacrylic acid ethylene glycol ester, and 44-59 pts. wt. deionized water. The stabilizer is polyethylene pyrrolidone.
