Proprietary Technologies

CAS Composite Anode Systems (CAS) focuses on the rehabilitation and maintenance of concrete structures endangered by the corrosion of the steel reinforcement. CAS disposes over a large knowledge base in the material science of building materials and on the corrosion of steel in concrete.


CAS attaches great importance to the sustainability of the by CAS proposed and employed technologies:


- minimize traffic disturbances and impediments
- create minimum traffic in applying the technologies
- use of sustainable materials and products
- create minimum, preferentially 0-waste by applying the technologies
- prolong service time of concrete structures at low costs with high reliability.

 

CAS developed a series of technologies that are within the scope of the above specifications.

 

CAST3+ Composite Anode System for the cathodic corrosion protection (CP) of steel in concrete. Part of this technology is the proprietary alumo-silicate based CAST3+ Composite Anode and a modular monitoring and control system with an integrated database for the on-line web based monitoring of structures and for the remote control of CP installations.

Solar CP with the CAST3+ Composite Anode System, operated with solar cells using the concrete structure as storage battery, and the LEDAC Low Energy Data Acquisition and Control System.

GCP – Solid Electrolyte system for the galvanic corrosion protection (GCP) of steel in concrete, consisting of a galvanic zinc anode embedded into a solid alumo-silicate based TAS-EZA electrolyte.

Modular Data Acquisition and Control System (MODAC) with an integrated SQL data-base for the online monitoring of steel reinforced concrete structures and for the remote control of CP installations.

Low Energy Data Acquisition and Control System (LEDAC) for the online monitoring of steel reinforced concrete structures and GCP installations and for the remote control of solar powered CP installations.

Automatic Control of CP Systems by a closed loop controller with macro cell currents measured by macro-cell sensors as input variable.
