Text of Abstract
Cement production is one of the leading contributors to global CO2 emissions. Geopolymers are ceramic-like binders that provide a sustainable alternative to cement with the potential to reduce up to 80% of CO2 emissions [Duxson et al., Cement and Concrete Research 2007, 12 (37), 1590-1597.] and enable in situ resource utilization (ISRU). Additive manufacturing (AM) is an exciting application of geopolymer technology with benefits including the design of complex structures and the potential to manufacture in harsh and extraterrestrial environments. The main challenge hindering wide adoption of geopolymers in AM is the complexity of controlling property development from initial chemistry. The chemical composition of geopolymer binders is known to impact macroscopic properties including workability and strength. Therefore, research connecting geopolymer chemistry and early-age rheological properties is required to design materials for successful AM applications.
