CIA National Durability Seminar Series

November 2014 : The durability of concrete structures remains a complex and difficult issue to design and manage due to many variables. Concrete Institute of Australia’s Durability Committee was formed in late 2008 to review “Durable Concrete Structures” with Task Groups formed, involving some of Australia’s leading durability experts, to produce a series of Recommended Practices as a major revision to the 1990 document. The Concrete Institute of Australia will present a one-day course in November that will provide an update on this work and provide guidance on durability design processes and practice that satisfy requirements for all concrete structure types. Attendees who register to attend the seminar in November 2014 will be the first to receive hardcopies of the newly published Z7/01 “Durability – Planning” and Z7/04 “Durability – Good Practice Through Design, Concrete Supply and Construction” Recommended Practice handbooks as part of the ticket price. Final draft copies of all other recommended practice notes except Z7/06 will also be included.

Giorgini Eurocorr Paper on CP Potential Criteria Identifies Issues

September 2014 : Roberto Giorgini has previously published a paper on the effect of active and passive bar potentials on the measured 24 hr decay potential of cathodic protection systems. In this paper he develops his ideas further using the same simple but very effective approach of measuring a sandwich of blocks with active and passive reinforcement being protected by a surface anode.  Although a general simulation of the effect of mixed potentials the set up mirrors protecting active corrosion of reinforcement on one face by applying an anode to the opposite face where reinforcement is passive, e,g, applying ZLA to the inside of parapet where the external face reinforcement is corroding. The results show that the current from the active area is changed from flow from the active reinforcement towards the passive reinforcement to flow from the anode towards the active and passive bars. However the potential shift of the active bars is minimal due to the polarising effects of the passive bars. This shows detailed consideration is required when applying the code criteria for CP of areas with strong mixed potentials. Download copy of the R. Giorgini paper.

Chess Eurocorr Paper Reviews Development of durAnode4 for ICCP of Historic Structures

September 2014 : Paul Chess reports on the development of the durAnode 4 and its use in historic structures since 1985. Since the original durAnode the following improvements have been made:

  • The resistor was moved from a box which supplied each individual anode into the anode body itself. This meant the larger chains of anodes became economic with better aesthetics.
  • The couplant was changed from a graphite base to a cement base which hydraulically set. This meant that the anode current density had to be reduced so a new perforated tubular structure was substituted for the rod.
  • The anode top was redesigned so that it could pierce the coated titanium feeder wire improving reliability and speed of installation.
  • A range of resistances are offered to allow customization of the current spread profiles of different anodes.


The paper outlines the 2004 installation of 12.5mm diameter durAnode 4 into mortar joints on the 1893 Marshall Fields Department Store in Chicago to protect steel columns encased in granite. Details of monitoring to 2010 are provided. Download copy of the P.Chess paper.

SRCP Appointed CPI Distributor fordurAnode4

April 2014 : CPI have developed the durAnode, the most popular internal anode system in the world and has a successful installation record dating back to 1986 with the original commercials system still operating on a Danish government owned and independently tested bridge support structure. They are also probably the largest automatic power supply manufacturer for cathodic protection of reinforced concrete in the world. CPI are led by Paul Chess, a well-respected international CP engineer. CPI are owned by Force Technology a pre-eminent European company in technology implementation. FORCE Technology targets its efforts at transforming highly specialised technological knowledge into practical and cost-effective solutions. SRCP visited CPI in April and met with their team and visited the production facility which also contains what is probably Europe’s largest titanium fabricator for CP components.

SRCP attended the Brisbane Corrosion & Prevention Conference and Exhibition Nov 11-13 2013. Brisbane Corrosion & Prevention Exhibition

November 2013 :  SRCP was on display at the Brisbane Convention & Exhibition Centre from Nov 11 - Nov 13 and were pleased to be able to show off our specialist products at such a fantastic exhibition. A chance to meet and catch up with new and old industry contacts was combined with participation in the technical debates, which lead to a number of individuals learning about SRCP's unique products and we would like to thank the ACA Queensland for hosting the expo, as well as all who took the time to visit the SRCP stand, opposite the PCTE NDT display.

SRCP will attend the SMAR conference on construction seeking the latest developments in repair methods. SMAR conference in Istanbul

September 2013 :  Monitoring of performance of existing structures is of vital importance as it enables owners to apply corrosion protection before damage occurs and repairs can become expensive. Where ICCP is installed a major cost is the monitoring. Hence efficient monitoring systems are a key part of asset management. SRCP will attend SMAR in Istanbul seeking methods that improve monitoring of structures and repairs.

1/5 September 2013 : corrPRE, developer of galvanic anodes uniquely designd for true CP of concrete, will exhibit at Eurocorr 2013, Europe's leading corrosion conference. Roberto Giorgini of corrPRE will present on their anodes and Mr Papworth will attend the conference. SRCP are attending in order to improve their understanding of the latest developments in corrosion.

Protector Workshop. Advanced training on Camur, Zebra & Cassette, Norway

29/30 August 2013 : SRCP team went to visit Protector for further training on Camur, Zebra & Cassette. Further in depth training was provided over 2 days into the Protector systems. SRCP gained insights that has over 10 years experience been bought to Protector through development of systems and installation of their CP systems.

24 July 2013 : F.Papworth, chairman of SRCP and PCTE will give a talk on assessing reinforcement corrosion. Before deciding which method of repair should be used it is important that the extent and cause of the problem be established. His talk will focus on the equipment and methods for surveys and testing of cathodic protection installation on reinforced concrete structures.

23 July 2013 : SRCP introduces their impressed current and sacrificial anodes. The three types of galvanic anode revolutionise patch repair as they eliminate the need for breakout of sound but contaminated concrete. The impressed current CP systems provide increased flexibility where control and monitoring are required.

Repair of balconyBalcony repairs using ZLA at Cottesloe

1 May 2013 : ZLA is frequently used for balcony repairs because it can be installed on the soffit where, because of its high output, it can protects the reinforcement on the deck and soffit faces. ZLA can be combined with Roll Anodes to protect the support at the building line. In May ZLA was specified for balcony repairs of Cottesloe beach apartments.

15 May 2013 : SRCP has supplied Roll Anodes for Cockle Creak Bridge piers. Extreme fibre stresses were a concern and SRCP advised that this could be overcome by pushing in the anodes so that the surface 100mm of the anode hole could be grouted with a high strength grout. Rarely is stress due to the drilled holes an issue but where it is design the anodes to be closer to the neutral axis.

10 September 2012 : SRCP has supplied ZLA for a trial on a pier of Figg Tree Bridge, NSW. Roberto Giorgini of corrPRE advises that the ideal anode arrangement for bridges is water anodes for the lower tdal zone, Roll Anodes for the upper tidal and splash zones and ZLA for the spray zone.
