Optimizing earthern construction using rheology
Prof. Arnaud Perrot
Université de Bretagne Sud

Abstract: Earth-based materials are currently receiving much attention as sustainable and local construction materials with sufficient mechanical strength for affordable solutions worldwide. However, contrarily to concrete and cement-based materials, only a few studies deal with the rheological behaviour of such materials and its link with processing route. It is worth noting that there is a broad range of processing routes for earth-based materials which impose different rheological or consistency requirements for the earth materials. Depending on its nature and the water content, earth materials can be granular-like, pasty or fluid-like materials making the material more adapted to specific processing routes than others. It is here shown that in vernacular construction techniques, the earth nature and achievable consistencies have imposed the processing routes and influenced the material hardened or service life properties. Inspired by these observations, it is now required to adapt the material “fresh” properties to the processing methods (or the contrary) in order to obtain the best of the materials in terms of mechanical and service life properties. To reach this goal, concepts taken from concrete mix design and processing as well as geotechnical and rheological characterization tools can be used and beneficially applied to earth construction. For example, using admixtures can be a solution in order to design and cast earth-like concrete or to meet rheological requirements for 3D printing methods. The presentation aims to provide an overview of earth construction methods with materials specifications and rheological requirements. Finally, the effects of different admixtures on earth processing are also presented with an emphasis put on bio-based solutions.

Know your building: the non-intrusive part of structural inspection
Miguel Gomes de Almeida
André Ferreira

Abstract: The acceleration of human impact on the planet since the 1950s has led to a substantial growth of Civil Engineering, aimed at solving the needs of progressively more ambitious and complex projects. The volume of problems presented to civil engineers is now further magnified by the progressive decay of many of the concrete structures built during the 20th century, and whose life span approaches critical stages. Under these conditions, the response of Civil Engineeres should be accompanied by paralell inspections able to retrieve critical information from the buildings and areas that are to be intervened.
The current development of remote sensing and non-intrusive inspection technologies responds directly to this challenge, multiplying the methods and techniques of underground surveying, structural inspection, and recurrent physical and geometric monitoring. There are a vast number of novel non-intrusive inspection technologies (georadar, seismic surveys, electrical methods, geomagnetic, thermography, laserscanning, photogrammetry, …), that allow to investigate different physical parameters and answer relevant questions for each specific case-study.
The potential of these new technologies will depend on:
– the development of integrated inspections protocols that couple non-intrusive methods with destructive tests and Reverse Engineering projects,
– the dissemination of technical information on these methods amongst land planners, architects, and civil engineers. These objectives are fundamental aspects towards more knowledge-based construction and rehabilitation projects.

From Matter to Shape: 3D Printing Precast Industry
Dr. Didier Lootens
Department Director of Material Physics, Sika Technology

Abstract: Additive manufacturing or 3D printing, already implemented in all industries is now also more and more used in the construction either on the field or in precast. Chemistry, process but also civil engineering, architecture have to be combined to able a successful and rapid implementation of environmental 3D construction printing. The initial challenges to print high quality and continuously at construction scales have been reached given us now the opportunity to spread the new technology for more efficient construction processes. The construction industry is changing rapidly with the increasing use of precast elements which allow safer, quicker and cheaper high-quality constructions. With the integration of 3D printing into the modular building process, we can further decrease the total cost with less  material that can do more. The environmental considerations involve the need to reduce the quantity of construction materials but also to increase their durability. This presentation demonstrates the use of 3D printing technology for new building principles.

Smart, Functional and Sustainable – the Future of 3D Concrete Printing
Prof. Sandra Lucas
TU/e Department of the Built Environment, Eindhoven University of Technology, Netherlands

Abstract: The construction industry is entering a new and exciting phase with the development of 3D printing. Concrete materials and structures can now be easily printed into much more complex shapes than before, however, the materials are still quite similar to the conventional concrete that has been used for many decades. Other very important changes that construction materials suffered over the last decade concern their functionality and sustainability. New materials with properties such as self-healing, self-cleaning and heat storage have been developed, and new binders were introduced to reduce the cement content. The next challenge in the construction industry is therefore merging these two worlds, the 3D printing of building and the production of functional and sustainable construction materials. This next step is now a reality at Eindhoven University of Technology, through two major projects supported by NWO (the Dutch research council) – ‘Additive manufacturing of functional construction materials on-demand’ and ‘Additive manufacturing of sustainable concrete for zero-energy buildings’.

Short Bio: Sandra Lucas is an assistant professor in 3D printing of concrete in the research group Concrete Structures at the TU/e department of the Built Environment (unit Structural Design). Sandra’s research goal is to understand how material’s modification can alter its microstructure, how this influences the macromechanical behaviour, creating new properties – self-healing, self-sensing, heat storage or self-cleaning, for example. At TU/e, her research focuses on transferring this knowledge to additive manufacturing, developing fully customisable 3D printed materials and buildings. She is the project leader of two NWO projects to develop smart and sustainable 3D printed concrete. Prior to this position, she was a senior lecturer in construction materials and sustainability at the University of Greenwich. She was the PI for several projects within academia and in collaboration with industry, through the Innovate UK funding agency.
Sandra Lucas obtained a BEng in ceramic and glass engineering, an MSc in environmental management and materials and, in 2011, a PhD in Civil Engineering from the University of Aveiro (Portugal). She then became a Marie Curie Postdoctoral researcher at the Fraunhofer Institute UMSICHT (Oberhausen, Germany) for the SHeMat project. As part of this project, she was a visiting researcher at EPSI ParisTech (Paris, France) and Delft University of Technology (The Netherlands). In 2014, she joined the University of Greenwich (London, UK) as a senior lecturer in construction materials and sustainability. In 2018, Sandra Lucas was appointed as an assistant professor in 3D printing of concrete with the research group Concrete Structures at the Department of the Built Environment of Eindhoven University of Technology (TU/e, the Netherlands).

3D Concrete printing: State of the Art and Structural Applications
Prof. Domenico Asprone
University of Naples Federico II, Italy

Abstract: 3D Concrete Printing (3DCP) technology belongs to the more general digital fabrication methods utilizing concrete, which allows obtaining architectural and structural elements efficiently and quickly. The form freedom enabled by digital fabrication with concrete (DFC) technologies provides advantages for a wide range of concrete based objects. Indeed, structural elements built through  3D printing technology have a high engineering potential. Such an innovative technology makes possible optimizing the material use – e.g. through the topology-optimization – the overall costs and the architectural effectiveness. However, being such an innovative field there are many challenges to be faced: rheological/mechanical material requirements at both fresh and hardened state, buildability performance during the layered extrusion process, the inclusion of a reinforcement. The design of the DFC structural elements must take account of the peculiarities of the overall construction process and it is often faced with a lack of specific guidelines. Therefore, scientific research in this field becomes a necessary means toward achieving the full potential of DFC.

Short Bio: Domenico Asprone got his PhD in Materials and Structures in 2010; he is Associate Professor of Structural Engineering at the University of Naples Federico II. His research interests cover different topics related to the technological innovation in structural engineering and constructions, ranging from the integrated sustainable design and the implementation of BIM methodologies into design, construction and management processes of civil works, to resilience and robustness of civil structures against natural and man-made hazards, sustainability of structural materials, components and systems, additive manufacturing and 3d printing techniques for the production of structural systems.
