| Abstract: | We study the ratio of different compressive strength and deformation under load and the relationship of each specimen through the compression test of the specimens of cementitious composite materia tube.We also study relations between different fiber content and compressive strength,and deformation failure regularity and energy absorption characteristics under lateral flattened and choose the most suitable fiber type and dosage. The results showed that: a reasonable mix and fiber content make the pipe of super toughness cementitious composite material have a high compressive strength and good energy absorption effect. |
