A new study titled “Impact of accelerator on rheological properties of cement composites with cellulose microfibers: 3D printing perspective” has just been published in the Journal of Building Engineering. The research, led by Eunsan Cho, Seongwoo Gwon, Soowon Cha, and Prof. Myoungsu Shin, explores how accelerators can enhance the buildability of 3D printed concrete containing cellulose microfibers. By systematically analyzing rheological properties such as yield stress, viscosity, and structuration rate, the study demonstrates that accelerators effectively offset the setting delays caused by fibers and significantly improve printability. This work offers new insights for advancing sustainable and high-performance 3D printed construction materials.
