Ecoventia's Technology

• Experience and know-how of the Group

  ECOVENTIA has developed cutting- edge- technology to offer its precast, pre-stressed concrete wind tower, backed by PACADAR Group. The latter is a leading company with over 60 years of experience in field of design, transportation and installation of precast concrete.

  Those are the reasons which makes ECOVENTIA able to offer the innovative solutions to meet targets for various market scenarios. Some of our capabilities include:

  • Flexible design to suit the client's requirements, that fits perfectly to working conditions and requests.Flexible production capacity – there is no minimum or maximum threshold.
  • The assembly process is designed to raise wind towers the most efficient way, up to 2.5 towers per week and team (however, the greater the team, the greater the capability).

• The added value of Ecoventia

  To meet these objectives, ECOVENTIA has designed a concrete tower composed of "sectors" or parts, which are designed for its optimal transportation, according to local laws, and which do not require expensive and / or complex transport structures.

  Once on site, only two cranes are needed for the assembly process, which takes place quickly and efficiently, with alternatives of the process offered to the client.

  To fulfill the demanding requirements of all kind that a concrete tower should meet when holding and bearing with the forces of the turbine, ECOVENTIA team has concluded that the best solution is the use of Steel Fiber Reinforced Prestressed Concrete.

• Advantages of the system

  The addition of fiber stitches to concrete, gives rise to the following characteristic properties, among others:

  • Steel fiber stitches sews together cracks in concrete forming a kind of "bridge" between the coarse aggregate, allowing a controlled formation of cracks, leading to a ductile behavior after initial cracking and preventing brittle fracture of it.
  • Increased abrasion resistance due to a reduction of cracking.
  • Provides excellent corrosion resistance, since controlling the crack opening and therefore entry of water.
  • Improved tensile strength, bending and shear, resulting in increased bearing capacity.
  • Provides additional capacity of resistance due to plastic moment redistribution in case of localized solicitations.
  • Achieves high resilience (ability to absorb energy of impacts) and impact resistance to dynamic stress.
  • Provides consistent reinforcement in three directions, making it an homogeneous isotropic material, with equal performance in all directions.
  • Due to the isotropic and uniform distribution of fibers in the whole structure It is Ideal solution for loads without defined point of application.
  • Allows material savings since the thickness can be reduced while retaining the same properties.

  On the other hand, in the prestressed concrete, the existing tensile stresses are being eliminated by introduction of compressive stresses before the application of external loads; and overlapping with these, the total permanent stresses, for all scenarios considered, are included between the limits that the material can endure indefinitely.
