Research on the Influence of Carbon Nanotubes on the Mechanical Properties and Microstructure of Solid Waste Concrete
Adding different proportions of carbon nanotubes(CNTs)to solid waste concrete,the influence of carbon nanotubes on the mechanical properties and durability,such as compressive strength,flexural strength,and tensile strength,was studied through experiments.The research results indicate that the appropriate addition of CNTs can significantly improve the mechanical properties of concrete.When 0.1%CNTs were added,the compressive strength and tensile strength of concrete increased by 16.19%and 19.41%,respectively.Carbon nanotubes can promote the hydration reaction of cement matrix,form more uniform hydration products,and significantly improve the microstructure of solid waste concrete,which makes the pore structure in solid waste concrete more dense.As can be seen from the above,CNTs can significantly improve the mechanical properties and microstructure of solid waste concrete,and effectively enhance its durability.The research provide a new approach for improving the performance of solid waste concrete and utilizing solid waste resources.
