Abstract

The application of carbon fiber in concrete is very extensive. This article conducts experiments on the mechanical and durability properties of carbon fiber-reinforced 3D printed concrete specimens by adding different amounts and lengths of carbon fiber to 3D printed concrete. The experimental results show that when the content of short cut carbon fiber is 0.2% and the length is 6mm, the compressive strength of 3D printed concrete in all directions reaches its maximum; When the dosage is 0.6% and the length is 6mm, its flexural strength and splitting tensile strength reach their highest values. Carbon fiber can effectively reduce the diffusion coefficient of chloride ions in 3D printed concrete, and its resistance to sulfate corrosion and frost resistance are also excellent. After 150 cycles of sulfate dry wet cycles and 200 cycles of freeze-thaw cycles, the highest compressive strength and corrosion resistance coefficient is 1.10, and the highest relative dynamic modulus is 78.9%. It is very suitable for use in harsh environments such as sulfate content.
