▎ 摘 要
NOVELTY - The arch rib comprises a graphene tube filled with self-compaction engineered cementitious composite (ECC) concrete. The graphene tube is made of graphene material with density of 2.25 gram per centimeter cube. The density of the self-compaction ECC concrete is 2.3 to 2.4 gram per centimeter cube. The self-compacting ECC concrete material includes short fiber material with high strength and high elastic modulus. The volume of the short fiber material does not exceed 3 percent of the volume of the self-compacting ECC concrete material. USE - Arch rib for steel pipe concrete arch bridge structure. ADVANTAGE - The graphene material is corrosion resistant, the density is small and the weight is light, with high strength, so as to avoid the steel pipe structure from corroding and rusting. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of arch rib for steel pipe concrete arch bridge structure.
