▎ 摘 要
NOVELTY - A reactive powder concrete comprises 670-710 pts. wt. cement, 80-120 pts. wt. silica fume, 230-270 pts. wt. coal ash, 1000-1050 pts. wt. quartz sand, 170-220 pts. wt. water, 31-35 pts. wt. water reducing agent, 130-170 pts. wt. steel fiber, 60-80 pts. wt. nanominerals, and 25-28 pts. wt. graphene oxide. USE - The reactive powder concrete is useful in large bridge, ocean engineering, high-rise building, and military engineering applications. ADVANTAGE - The reactive powder concrete: forms ultra-dense structural system; has excellent water resistance, compressive strength of 225-270 MPa, and tensile strength; is not easily corroded by external substances; resists the corrosion of chloride ions; improves the durability of components; and can be prepared by a method, which uses less amount of cement, reduces carbon dioxide emissions, is environmentally-friendly, and can be carried out industrially on a large scale. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of the reactive powder concrete; and (2) use method of the reactive powder concrete.
