▎ 摘  要

NOVELTY - A high-toughness and high-strength hybrid fiber concrete comprises 525-535 pts. wt. cement, 735-740 pts. wt. sand, 890-900 pts. wt. gravel, 70-80 pts. wt. fly ash, 85-95 pts. wt. straw ash, 95-100 pts. wt. silicon ash, 4.7-5 pts. wt. nano-silicon, 90-95 pts. wt. water, 17-18 pts. wt. water reducing agent, 14.5-15 pts. wt. excitant, 2.5-2.9 pts. wt. antifoaming agent, 12-13 pts. wt. shrinkage reducing agent, 6.5-6.7 pts. wt. Ramie fiber, 12.2-12.5 pts. wt. basalt fiber, 19-19.3 pts. wt. calcium carbonate crystal whisker, 33-36 pts. wt. nanotitanium/graphene oxide dispersion liquid and 20.5-22 pts. wt. carboxyl modified polyvinyl alcohol polymer. USE - High-toughness and high-strength hybrid fiber concrete. ADVANTAGE - The hybrid fiber concrete has high strength, high toughness, high bonding property and high durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for potassium removal treatment method comprising putting straw ash in distilled water, stirring and soaking, standing, pouring supernatant liquid, continue adding distilled water to stir and soak, repeating this process more than 5 times, and soaking for one week; pouring supernatant liquid for last time, heating with distilled water to 90 degrees C, keeping for 15-20 minutes, keeping warm, pouring supernatant liquid, adding distilled water to soak, and repeating first step; repeating first and second steps; and keeping at 60 degrees C for 2 hours, pouring out supernatant, and drying.
