▎ 摘  要

NOVELTY - High-strength emergency concrete comprises 350-550 pts. wt. cement, 30-50 pts. wt. fly ash, 30-100 pts. wt. slag, 700-900 pts. wt. fine aggregate, 900-1200 pts. wt. coarse aggregate, 0.8-1.2 pts. wt. polycarboxylic acid water reducing agent, 0.3-0.5 pts. wt. triethanolamine, 0.4-0.6 pts. wt. triisopropanolamine, 1-1.5 pts. wt. carbon fiber, 0.3-0.5 pts. wt. carbon nanofiber, 1-2 pts. wt. polymer emulsion, 1-3 pts. wt. reinforcing agent and 140-200 pts. wt. water. The reinforcing agent is nylon fiber and/or polypropylene fiber. USE - The emergency concrete is useful for repairing and reinforcing reservoir dam, hydropower station, building, and important building material. ADVANTAGE - The high-strength emergency concrete has high strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of high-strength emergency concrete.
