Zinc Electrodes for applications in sea water

Zinc with an elevated purity reacts once in sea water as a pseudo-reference electrode, and presents an excellent stability in the time.CESCOR has realized a series of assemblings for various applications in sea water:
  • Platforms
  • Piers and other underwater metallic structures
  • Equipment.

Concrete

Corrosion in concrete – Monitoring and protection

The corrosion of steel reinforcements is the principal cause of degradation of reinforced concrete structures. Besides its inspection services, CESCOR offers specific products for the permanent monitoring.

The Ti-MMO electrode allows, very easily, the measurement of the potential of the steel reinforcements and the assessment of the corrosion state of the steel reinforcement in aerial civil structures. The same electrode can be employed in cathodic protection systems for reinforced concrete and for the monitoring of electric interferences in civil works such as subways and railway lines.

The MūRE probe also offers a wide range of applications for the permanent monitoring of corrosion in concrete.

In addition to monitoring, CESCOR also offers a wide range of cathodic protection solutions of the steel reinforcements, both with impressed currents systems and through galvanic anodes

  • Ti-MMO Electrode
  • MūRE
  • Corrosion monitoring systems
  • Cathodic protection systems
  • Galvanic anodes for concrete

CESCOR supplies cathodic protection system components and monitoring systems, as well as corrosion and stray currents monitoring probes.

SCMS Control Unit 

The SCMS (Stray Current Monitoring System) Control Unit is specifically designed to monitor the presence or occurrence over time of interference conditions, for example due to direct current traction systems (railways, tramways, undergrounds, etc.), with consequent corrosion damage on reinforced concrete structures. The system performs a continuous registration of the potential of the structure to be monitored by means of permanent reference electrodes in activated titanium (Ti-MMO). The system records and processes the potential difference data between the steel reinforcements embedded in concrete and the Ti-MMO electrodes, generating alarms if certain thresholds defined by current normative are exceeded.

Datalogger DL852C

The Datalogger DL852C is a portable, pocket-sized, two-channel device, specifically designed to meet the needs of monitoring the cathodic protection of underground metallic structures or in contact with environments not immune to corrosion phenomena. The device provides measurements of the electrochemical potential of the steel structure to be monitored and of its possible variation over time due to electrical interference conditions. The DL852C is used for data collection to be carried out automatically on site. After having programmed it in the office or directly in the place of use, the DL852C is then connected both to the reference electrode (portable or permanent) and to the structure to be monitored and, therefore, activated by means of a specific switch. At the end of the monitoring campaign, the measurements collected by the DL852C must then be transferred to an external PC for data analysis.

Ti-MMO Electrode

It is a permanent reference electrode for the control of corrosion in reinforced concrete structures. It consists of a probe of titanium activated with mixed metal oxides, enriched by iridium, - and immersed in a specifically designed mortar that maintains the pH around the probe constant and guarantees over time the long term stability of the electrochemical potential. The applications include: corrosion monitoring, stray currents monitoring, and the control of cathodic protection.

MūRE

MūRE is a probe for the monitoring of corrosion in reinforced concrete structures. It consists in a series of linear reference electrodes in nickel. It supplies the mapping of potential of the steel reinforcements. It tracks the pitting trigger and it allows to preventively diagnose hydrogen embrittlement conditions in high resistivity steels. It is the only reference electrode for the monitoring of pre-stressed and post-tensioned concrete structures.
