Chen, Y. (author), Zhang, Y. (author), He, S. (author), Liang, X. (author), Schlangen, E. (author), Copuroglu, Oguzhan (author)In 3D concrete printing, fast structuration is a prerequisite for ideal buildability. This paper aims to study the impact of inorganic additives, i.e., CaCl<sub>2</sub> and gypsum, on structural build-up and very early-age hydration of limestone-calcined clay-cement (LC3) pastes within the first 70–80 min. Results show that, increasing the...journal article 2023

Chen, Y. (author), Liang, M. (author), Zhang, Y. (author), Li, Z. (author), Šavija, B. (author), Schlangen, E. (author), Copuroglu, Oguzhan (author)Autogenous shrinkage may be a critical issue concerning the use of limestone-calcined clay-cement (LC3) in high-performance concrete and 3D printable cementitious materials, which have relatively low water to binder (W/B) ratio. Adding an internal curing agent, i.e., superabsorbent polymer (SAP), could be a viable solution in this context....journal article 2023
