UHPC - DUCTAL®

UHPC DUCTALw

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.

¿WHY 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

ADVANTAGES DUCTAL®

  • 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®

Production planning

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.

Además estamos trabajando activamente en otros dos proyectos financiados con fondos propios junto con investigadores de la Universidad Politécnica de Madrid y de la Universidad Politécnica de Cataluña:

  • SIMULAMAT: Proyecto de Investigación que consiste en la creación de un software avanzado  de simulación de propiedades de resistencia de materiales a partir de los parámetros de fabricación del hormigón. Proyecto desarrollado en colaboración con el Departamento de Ingeniería Forestal de la Universidad Politécnica de Madrid. 
  • PNFU: Proyecto de Investigación donde se estudia la influencia de la incorporación de polvo de neumático fuera de uso como sustitución parcial de los áridos del hormigón para su uso en el sector de la construcción. Proyecto en colaboración con el Departamento de Ingeniería de la Construcción de la Universidad Politécnica de Cataluña. 

NUEVO COLEGIO ALEMAN, MADRID, Cubrir Aguas

Altas personalidades del gobierno y la embajada alemana presidieron el pasado día 25 de marzo la celebración de cubrir aguas en la obra del Nuevo Colegio Alemán en Monte Carmelo, a la que también asistió una representación de Prehorquisa.

http://www.spanien.diplo.de/Vertretung/spanien/es/00-startseite/bildergalerie-richtfest-DSM.html

Prehorquisa ha participado en la mayor obra civil del gobierno federal fuera de Alemania, al suministrar los 1.077 pilares arquitectónicos inclinados que dan forma y personalidad a las fachadas del nuevo colegio alemán en el barrio de Montecarmelo en Madrid.

Todo el proyecto de prefabricación ha sido desarrollado por el departamento tecnico de Prehorquisa bajo la normativa y estándares alemanes, en estrecha colaboración con el equipo de obra de FCC, para la consecucion de los objetivos previstos.

Os dejamos un enlace donde puede verse en directo la evolución de la obra y otros con algunas noticias al respecto de la obra:
