The introduction of digital manufacturing techniques, such as 3D printing applied to concrete material, opens up new perspectives on the way in which buildings are designed. Research on this theme is thriving and there is a high rate of innovation related to concrete. At the same time, the first life-size constructions made from printed concrete are emerging from the ground. This book presents state-of-the-art knowledge on the different printing processes as well as on the concrete material that must adapt to these new manufacturing techniques, such as new hardware and new printers for concrete. The possibilities in terms of architectural design are discussed as well as the pathways that remain to be uncovered. The book also explores the challenges that researchers and companies expect to overcome as they get closer to democratizing this potential revolution that is the digital manufacturing of concrete.

This book presents a comprehensive overview of the state of the art in additive manufacturing in the world of concrete construction.

3D Concrete Printing tackles its subject from several angles, including issues relating to concrete materials (such as their formulation or fresh-state behavior), the various printing processes that have been developed, and how to describe the mechanical behavior and architectural and structural designs of printed structures. This book also considers the transition to application and industrialization, and the relevance of these new technologies in reducing the environmental impact of the construction sector.

Finally, material characterization methodologies are presented with a view to describing the behavior of materials both before and after printing, and the modeling tools used to simulate the process are listed.

Les modernes ont souvent opposé les chrétiens à l’hellénisme. Les auteurs antiques eux-mêmes – qu’ils soient « Grecs » ou chrétiens – semblent avoir thématisé leur antagonisme. Que vaut cette ligne de fracture ? Qu’est-ce qu’être Grec à la fin de l’Antiquité ? Pour quelles raisons un chrétien hellénophone, passé par les écoles de l’Empire et nourri de paideia, ne saurait-il être un Grec, au même titre que les autres ? Qui donne, qui revendique et qui refuse ce titre – et pourquoi ? Les termes dans lesquels le sujet est posé ne sont ni simples, ni neutres. La notion d’hellénisme, qui peut paraître moins confessionnelle que celle de « paganisme », est en réalité marquée par les conflits religieux des époques hellénistique et tardive. Ce sont, on le montrera, les besoins de l’autodéfinition et l’élaboration de la polémique contre l’Autre qui conditionnent les rapports entre les chrétiens et « l’hellénisme ». Cet ouvrage porte une attention particulière au but poursuivi par les auteurs anciens dans chacune de leurs déclarations identitaires, entre langue commune et particularisme religieux.

This book gathers the peer-reviewed papers presented at the Second RILEM International Conference on Earthen Construction (ICEC), held in Edinburgh, United Kingdom, on July 8–10, 2024. It highlights the latest advances and innovations in the field of con earth-based building materials and construction. The conference topics encompass material characterisation and quality control, hydro-mechanical behaviour, reinforcement behaviour, seismic behaviour, in situ and field testing, additive manufacturing (3D printing), rheology, biostabilisation, molecular simulation, microstructure, durability, fire performance, hygro-thermal behaviour, life cycle analysis, climate change adaptation, economic impacts, and earthen architecture. As such, the book represents an invaluable, up-to-the-minute tool, and offers an important platform to engineers, architects, and geophysicists.
