The Applicability of the Wenner Method for Resistivity Measurement of Concrete in Atmospheric Conditions
Case Studies in Construction Materials Volume 15
2021
This paper presents an innovative and practical method utilising existing Wenner Probe equipment, capable of eliminating and/or minimising the influence of these factors in atmospheric conditions. The new method minimises the impact of concrete surface variability by establishing an alternative, reliable electrolytic contact between the Wenner equipment probes and concrete.
Grout Acidification of Ribbon Anode in Impressed Current Cathodic Protection Systems in Concrete Structures
EUROCORR, Spain
2019
This paper verifies a methodology for the prevention of grout acidification in ICCP systems. The results presented in this paper confirm that insufficient anode embedment, often combined with poor quality control and workmanship during ICCP system construction, allow water to ingress to the ribbon anode and these are the primary causes of localised grout acidification.
New Innovation For ICCP Current Delivery to Concrete Structures
ACA, Corrosion & Prevention, Australia
2019
The development of new and innovative methods of reliable current delivery for ICCP systems in conjunction with simplifications in the design, installation and monitoring of these systems can substantially reduce the complexity and the cost of ongoing maintenance and ensure that less effective galvanic based systems are not selected for the long term maintenance of infrastructure assets.
