Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of electronic components and the technical field of material preparation, and specifically relates to a composite material. [0003] 【Background technique】 [0004] Concrete is widely used in industrial and civil construction, road and bridge engineering, airports, ports and water conservancy projects. Concrete structure buildings, especially major engineering structures such as super-long-span bridges, key water conservancy projects, key sports venues, large ocean platforms, nuclear power plant projects, and high-speed railway construction, generally have a design life span of decades or even hundreds of years. During the long-term repeated exposure to various loads, long-term erosion of the natural environment such as acid rain, and the aging of the material itself, it will inevitably lead to damage to the civil engineering structure, which may cause sudden disasters and cause great losses to the s...
