▎ 摘　　要

NOVELTY - A concrete anti-cracking agent comprises 1.5-4 pts. wt. modified anti-cracking fiber, 2-7 pts. wt. modified kyanite, 5-8 pts. wt. modified montmorillonite, 0.5-1 pt. wt. graphene oxide, 1-3.5 pts. wt. polymer microspheres, 2-4 pts. wt. nano dysprosium oxide, 2-4 pts. wt. nano zinc oxide, and 10-30 pts. wt. gypsum. USE - Concrete anti-cracking agent used in concrete structure for preventing or reducing concrete cracking. ADVANTAGE - The concrete anti-cracking agent utilizes the modified fiber that can reduce shrinkage of concrete, prevent crack growth, improve toughness of concrete and improve the durability of the concrete, utilizes the polymer microsphere that is helpful for filling the crack in the crack-resistant concrete, and utilizes the graphene oxide that has a two-dimensional net-shaped structure, large specific surface area and very high elastic modulus. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the concrete anti-cracking agent. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart illustrating preparation of the concrete anti-cracking agent. (Drawing includes non-English language text)
