Additive manufacturing and digital fabrication bring new horizons to concrete cement-based material construction. 3D printing inspired construction techniques that have recently been developed at laboratory scale for materials. This study aims investigate the role of structural build-up properties materials in such a layer by technique. As progresses, become harder with time. The mechanical strength must be sufficient sustain weight layers subsequently deposited. It follows comparison...
Extrusion is a process that consists in forcing formable material to pass through die having the cross-section of part be obtained. This way processing used with conventional and fibre-reinforced cement-based materials fabricate various construction elements such as panels, pipes roadside curbs. Recently, development digital fabrication methods especially 3D concrete printing by selective deposition, extrusion techniques have experienced significant increase interest.

Today, the extrusion-based 3D printing of concrete is a potential breakthrough technology for construction industry. It expected that will reduce cost civil engineering structures (removal formwork) and lead to significant reduction in time improve working environment conditions. Following use this additive manufacturing layer-wise process, it required change way are designed reinforced, especially parts structure under tension loads. Indeed, process does not allow production conventional...
The use of excavated earth is a circular and carbon neutral solution gaining growing interest. However, its high variability in properties makes it difficult to master as raw materials for construction. objective this paper highlight the key parameters allowing overcoming influence soil composition on earth-based concrete properties. We show that solid volume fraction clay paste parameter predicting fresh state binder, whatever constitutive type, whereas activity dry density material control...
3D printing technology (3DP) has provided new design and structural opportunities for cement-based systems (CBS) in architectural construction. However, there are still some issues related to extrudability buildability of CBS, which can be overcome by using components CBS rheology control. In this study, three types nanoclays, a bentonite (BEN), sepiolite (SEP) an attapulgite (ATT), two viscosity modifying admixtures (VMAs), poly-acrylamide (VMA1) methylcellulose ether (VMA2), were added...
With the overall aim of supporting development new construction techniques and materials that are more economical less carbon intensive, RILEM has decided to launch three technical committees on earth in 2022. One these will focus manufacturing processes used (TC PEM). The this committee is bring together experts from several disciplines (materials science, construction, rheology, geotechnics, cement chemistry, etc.) advance by sharing promoting good practice. processing today based solid...
This study focuses on heat conduction in unidimensional lattices also known as microstructured rods. The lattice thermal properties can be representative of concentrated interface phases one-dimensional segmented exact solution the linear time-dependent spatial difference equation associated with problem is presented for some given initial and boundary conditions. compared to quasicontinuum approximation built by continualization equations. A rational-based asymptotic expansion...
In this paper, to have control over geometry specifications of rectangular bar-shaped layers in a robotic concrete 3D printing process, real-time vision-based framework is developed and proposed. The proposed system able set the layer-width by automatically adjusting velocity an industrial manipulator during process based materials relying on vision feedback. Initially, details related system, processing units, platform are discussed. continue, technical descriptions printhead design,...
