Ultra-High-Performance Concrete Panels
UHPC - DUCTAL® Ultra-High-Performance concrete (UHPC)
¿WHAT IS UHPC?
Ultra-High-Performance Concrete (UHPC) is generally defined as a concrete with a characteristic resistance to compression >100 MPa, UHPC is reinforced with metallic (normally) or organic fibres. It is made of very fine sands, cement, flying ashes, silica smoke and a very low ratio of water cement (w/c < 0.20)
¿WHAT IS DUCTAL®?
Ductal is the name of the UHPC designed and developed by LAFARGE-HOLCIM with which we work, being the only company in Spain audited and authorized to work with Ductal.
We work with Ductal as it is a highly proven product. It has been used worldwide for over 20 years in all types of projects and by the most prestigious architects and engineers: DUCTAL® Projects
Mechanical properties. Exceptional durability and impact resistance. 110 to 200 Mpa compression.
Durable. Minimo mantenimiento. Minimum maintenance. Abrasion resistance and ice/thaw cycles.
Finish. Very fine internal structure (particles).
Impermeability. Very low porosity and not connected.
DUCTAL ® is impermeable
- Very Compact-Waterproof-Durable: Ideal for harsh environments
- Small panel thicknesses and low weight
- Complex geometrics without armor: lattice, slats, double skin curtain wall panels, ventilated facade...
Process in precast UHPC-DUCTAL®
Generally, the phases of the production process are as follows:
Development of the precast project by our technicians based on the instructions obtained from the work, making elevation plans, meetings details and anchors, three-dimensional models, calculation report...
Execution (based on agreed timeframe) of the number of molds required for the consequence of the objective.
Self-compacting UHPC pouring, not needing vibration nor embedding placement. (the process is variable depending on the type of panel to manufacture).
Withdrawal of the precast panel to the collection, sites, where they will be given the final treatment, as well as the corresponding cosmetics.
On-site transport on supports that protect the precast panels.
Setting up with the help of auxiliary cranes for the handling of the panels.
