Demonstration and Prototyping

All the technologies developed during the EnDurCrete project will be tested at demonstration level: 

  • Novel EnDurCrete cements and mix designs;
  • Corrosion inhibitors;
  • Sensorized textile reinforcement;
  • Multi-functional protective coatings.

    Maritime port in Spain

    mapPuerto de Musel, in Gijón - North of Spain, located in a small wharf in the North of the port where ACCIONA is currently carrying out research works, EnDurCrete specimens will be hold by metallic structures.

    The exposure classes to be considered are XS1, XS2, and XS3. Multiple  testing zones are going to be adopted: 

    • Aerial: specimens not in contact with water;

    • Tidal: specimens subjected to tidal cycles; 

    • Submerged: specimens totally under water.


    • Electrical impedance on the 4 panels dedicated to self-sensing; 2 panels will be placed in the aerial zone, the other two in the tidal one.

    • Environmental data (temperature, RH, etc.) will be monitored capturing data from the closest weather station.


    • Non‐Destructive Testing: Computer Vision (CV) and thermography (system mounted on a drone) on a pre-cracked panel placed in the aerial zone. 

      • Surface Resistivity Testing:  electrical resistivity of concrete panels with a 4‐point probe system (Resipod proceq, compliant to AASHTO T  358) at  specimen installation and after 12 months of exposure.  

      •  Destructive Testing:  

    - Compressive strength 

    - Porosity 

    - Sulphates attack and related micro‐level analyses with SEM/EDAX 

    - Carbonation testing

    - Freeze‐thaw

    - Chloride diffusion test 

    - Water penetration test to derive water permeability


    Tunnel in Spain

    Demonstrator located at Fundación Santa Bárbara, La Ribera del Folgoso, Leon - North of Spain, 7 panels (2 of them 4 meters long) will be installed.


    • Self‐diagnosis property will be assessed by optical fibers

    • Environmental sensors: commercial environmental sensors (T and RH)

    • Electrical impedance on the 4 panels dedicated to self-sensing


    • Non‐Destructive Testing: CV and thermography on a pre‐cracked concrete panel

    • Destructive Testing:

    - Compressive

    - Porosity

    - Freeze‐thaw

    - Water penetration test to derive water permeability


    Offshore structure in Norway (Stord, Norway)

    The exposure classes of offshore demo site are XS3 and XF4. Three different testing zones for specimens are being set‐up: 

    • Above splash zone: specimens not in contact with water; 

    • Splash: specimens subjected to splashes of water; 

    • Submerged: specimens totally under water.


    • Durability of self‐diagnosis property will be assessed by means of checking the optical fibers behavior over time

    • Corrosion sensors

    • Environmental sensors

    As for periodic testing on small specimens, the following tests are going to be performed

    • Destructive tests:

    - Compressive strength 

    - Porosity 

    - Freeze‐thaw

    - Chloride penetration test to derive chloride content


    Bridge in Croatia

    bridfeKrk Bridge, Croatia, North Adriatic Sea in Croatia, the bridge has been built between 1976 and 1980, and since then it has gone under numerous maintenance and remediation measures, due to the corrosion problems. Due to the very aggressive marine environment, it is suffering from durability corrosion problems mostly caused by corrosion of reinforcement.

    The exposure classes of the bridge demo site are XS1, XS2, and XS3. There are multiple testing zones for specimens:

    • Splash: specimens subjected to splashes of water;

    • Tidal: specimens subjected to tidal cycles;

    • In‐water: specimens totally submerged.
