▎ 摘　　要

NOVELTY - High-strength anti-seepage composite concrete, comprises 270-330 pts. wt. cement, 165-190 pts. wt. superfine fly ash, 50-80 pts. wt. slag powder, 500-720 pts. wt. sand, 700-900 pts. wt. crushed stone, 3-5 pts. wt. additive, 7-10 pts. wt. modified hemp fiber, and 180-200 pts. wt. water. The modified hemp fiber is obtained by coating the graphene-based film on the surface of the hemp fiber. USE - The concrete is useful as building material in high-rise building structure, large-span bridge structure and special structure. ADVANTAGE - The concrete has excellent durability, improved corrosion resistance, mechanical strength and elasticity, reduces the probability of crack generated by the concrete structure, and effectively improves the durability of the concrete impermeability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing high-strength anti-seepage composite concrete.
