Aérodynamique du béton projeté
Technologie d'automation
Planification de mouvement robotique
Développement durable
CHALLENGE
Although used for several decades, shotcrete generates a lot of waste up to 30% and generates a lot of dust. The concrete is sprayed in an inhomogeneous way generating variations in the quality of the structures
SOLUTION
Modeling, simulation of the Nozzle and Mixing Chamber and prediction of particle speed.
Using modeling, simulation and prediction of the concrete flow enable us to optimum strength performance and control the spraying properties (Particle speed, flow and pressures Homogeneity)
BENEFITS
-
Waste and rebound reduction
-
Concrete strength enhanced
-
Particle speed optimization
CHALLENGE
Shotcrete is managed by feeling not by data.
Sprayed concrete has always had variations due to many parameters related to fresh concrete properties manual spraying process, temperatures etc.
These variations lead to variations in the spraying process and hamper the compaction and therefore the durability of infrastructures.
SOLUTION
Automation of a multi-component platform.
We integrate sensors in the spraying line for real-time control and use artificial intelligence (AI) algorithms to automate the system. The automation system uses a Programmable Logic Controller (PLC) that controls robots, pumps and air compressor in real time.
BENEFITS
-
Process control
-
Concrete strength enhancement
DÉFI
Le travail manuel génère beaucoup d’incohérences de production dans les structures en béton. Le coffrage prend du temps et ralentit le processus de construction.
SOLUTION
Algorithme pour une planification de trajectoire à 7-DoF Nous utilisons une tête de projection brevetée, montée sur un robot industriel.
Nous utilisons divers cadres et outils avancés pour développer un logiciel qui traite les paramètres de conception et génère la trajectoire de projection.
AVANTAGES
-
Grande flexibilité de conception Plus besoin de coffrage.
-
Gain de temps et utilisation judicieuse de la main-d'œuvre.
-
La compaction optimale du béton est garantie

Elle est encore moins durable si le mortier spécialement conçu est transporté sur des milliers de kilomètres vers le point où il sera imprimé.
SOLUTION
Our additive manufacturing technology using shotcrete allows the use of local and conventional materials with usual amounts of cement.
It allows the use of ecological cements and recycled raw materials. We allow a true circular economy of building materials and help our customers to reduce their ecological impact.
The layers sprayed onto each other adhere by kinetic energy, which confers exceptional mechanical properties and durability for additively manufactured elements.
Control of the spraying process reduces rebound waste and minimizes the need for concrete.
BENEFITS
-
CO2 savings> 30% and lower consumption of primary materials.
-
Use of recycled materials and “green cements”.
-
Circular economy reducing the nuisances linked to the transport of materials.
-
Cost reduction
