| Abstract: | Concrete is the most widely used construction material,and carbon nano-fiber has many advantages in mechanical properties such as high strength,high Young's modulus.In this paper,the mechanical properties of concrete containing carbon nano-fiber(CNF) were experimentally studied by conducting uniaxial compression test and split tensile test.The test results indicate that the compressive strength and split tensile strength while loading concrete containing CNFs are greater than those of plain concrete.Finally... |
