Investigation of fresh and hardened properties of 3D printable concrete containing ozone-modified carbon fiber
In this study, the effect of using carbon fiber surface modified with ozone on the fresh-hardened state properties, high temperature resistance and rheological properties of 3D printable concrete (3DPC) was investigated. A total of 7 different 3DPC were prepared by adding modified and unmodified carbon fibers to the mixture at different ratios. Fiber surface modification was characterized by XPS analysis. The modification process improves the fiber/matrix adherence of 3DPC mixtures, resulting in an increase in compressive strength. The flexural strength of the mixtures increases with fiber modification, regardless of the fiber utilization ratio. Dynamic yield stress and apparent viscosity values of the mixtures decreased with the increase in fiber utilization ratio. τ3.p/τ2.p and Athix methods are more suitable for comparing the thixotropic properties of 3DPC mixtures with modified fibers suitable for comparing the thixotropic properties of 3DPC mixtures with modified fibers.
