Overview of CP-Compass-Concrete - Design Calculation for Cathodic Protection of Reinforced Concrete Structures
CP-Compass-Concrete is the only device and OS independent software tool on the market for design calculation for cathodic protection of reinforced concrete structures. Designers, architects, engineers, consultants, operation personnel, maintenance and inspection engineers can quickly determine the cathodic protection current requirement based on the current condition of the RC structure (Figure 1 below), anytime, anywhere, on any device running any OS without the need to install or download anything. CP-Compass-Concrete also predicts the effectiveness of cathodic protection and the minimum cathodic protection polarization required to reduce the corrosion rate to a level that can meet the design life of the RC structure.
Impressed current cathodic protection (ICCP) can be applied to reinforced concrete structures exposed to atmosphere, buried in soil, or submerged in water (Figure 1). Galvanic anode cathodic protection can be applied to the buried or submerged reinforced concrete structures (Figure 2).
Using CP-Compass-Concrete is as easy as 1-2-3.
(1) Enter the design data.
(2) Select the service environment.
(3) Review the design calculation results.

CP-Compass-Concrete complies with applicable international standards and relevant industry best practices such as BS EN ISO 12696, NACE SP 0290, NACE SP 0187, and AS 2832-5. Users of CP-Compass-Concrete simply select the applicable standard from the dropdown list (Figure 3) and the software modeling engine will determine the optimized design current density based on the assessment of the current condition of the RC structure including the age, design parameters, exposure environment, service environment, and the remaining life. The software is also flexible, giving users the option to override the standards and specify the design current density (Figure 4).

The predictive engine in CP-Compass-Concrete also assesses the existing condition of the concrete structure and determines the minimum CP polarization required to meet the design or remaining life of the RC structure. As shown in Figures 1 & 4 above, for the 15-year old RC structure, the minimum CP polarization required to meet the design life of 50 years (or the remaining life of 35 years) is 60.51 mV. The protection criteria by design is 100 mV. The corrosion reduction factor at the 100 mV CP polarization is 60 and the corrosion rate of the reinforcement under cathodic protection is 0.0003 mm/y (0.3 um/y). Cautionary remarks pertaining to hydrogen embrittlement of prestressing steels are also provided.
The powerful applications of CP-Compass-Concrete are truly unlimited in engineering design, concrete corrosion prediction and modeling, cathodic protection design and optimization, and remaining life prediction of RC structures under the various service environments.
