About

Pierre-Antoine Andreani is a leading figure in the field of digital construction and advanced materials, with a primary focus on the rheology and structural build-up of early-age concrete for 3D printing applications. His most-cited work, "Evaluation of Early-Age Concrete Structural Build-Up for 3D Concrete Printing by Oscillatory Rheometry" (2019, 25 citations), provides a foundational methodology for assessing the critical thixotropic behavior of printable concretes. By employing oscillatory rheometry, Andreani established a robust framework to quantify how concrete gains structural integrity immediately after extrusion—a key parameter for ensuring layer stability and print fidelity without mechanical collapse. This contribution directly addresses one of the central challenges in 3D concrete printing: balancing flowability during pumping with rapid strength gain after deposition. His research has been instrumental in advancing the practical viability of additive manufacturing in construction, influencing both material design and process control. Through his work, Andreani has helped bridge the gap between rheological science and large-scale digital fabrication, making him a notable contributor to the ongoing evolution of sustainable, automated building technologies.
