01

Aerodynamics
of sprayed concrete

CHALLENGE

Generation of waste 20-30%.

Dust generation due to insufficient wetting conditions.

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

02

New Automation Technology

 
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

03

Robotic
Fabrication

 
CHALLENGE

Manual labor generates lots of inconsistency in concrete structures.

Formwork takes time and slow down construction process.

SOLUTION

Algorithm for 7-DoF trajectory planning.

We use a patented spraying head mounted on an industrial robot. 
We utilize various advance frameworks and tools to develop a software which processes the design parameters and generates the spraying trajectory. 

BENEFITS
  • High flexibility of design.
     

  • No more formwork.

  • Time saving and wise usage of workforce

Sustainable Construction Materials

 
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

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.

AVANTAGES
  • 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
