摘要
Abstract
To enhance the durability of the concrete structure of the transmission and transformation line foundation in the alpine and high-alti-tude areas,ensure the quality of the transmission and transformation line project,and avoid the freezing damage of concrete by cold tempera-tures in winter construction.In this experiment,the mechanical study of concrete doped with polypropylene fiber under the same condition of curing was carried out.The basic mechanical properties of PPFC in alpine and high altitude areas were studied through comparative tests of polypropylene fiber reinforced concrete(PPFC)and concrete(C).The research findings reveal that the cubic compressive strength of concrete is significantly enhanced When polypropylene fibers are added to concrete at a 1%content,the splitting tensile strength of the material increa-ses by 19.5%compared to plain concrete and the flexural strength is increased by 5.54%.关键词
