Over the years, my group at Tennessee Tech has been supported by a number of industry and government agencies. The following includes a few highlights and a more detailed list of projects in chronological order from most recent.

Highlight - Printing with cement-based materials
PrintingVideoNoAudio.mp4Printing with cement-based materials is difficult, but cement rheology can be controlled by using various additives. We explored the use of hydrogels and developed a highly printable hydrogel-based cement past, see: H. Taheri Afarani, W. Carrol, E. J. Garboczi and J. J. Biernacki, Designing 3D Printable Cementitious Materials with Gel-Forming Polymers, Construction and Building Materials, 268, 121709 (2021), https://www.sciencedirect.com/science/article/abs/pii/S0950061820337132.
Highlight - Modeling paste printing
2DSCPVideo.mp4As part of our efforts to predict paste printing outcomes, we developed and introduced a modeling strategy that we call "2D-Stationary Computational Printing (2D-SCP)," see: A. S. Mohammad and J. J. Biernacki, 2D stationary computational printing of cement-based pastes, Cem. Concr. Res., 159,106866 (2022), https://doi.org/10.1016/j.cemconres.2022.106866.The 2D-SCP strategy models a 2D slice through the printed material, layer-by-layer to simulate the stacking in space and time. The method was shown to accurately predict print failure heights when compared to experimental results.
