The Condition of Post-Tensioned Concrete Bridges

In major upgrades and extensions of highway networks over the past sixty years, the use of post-tensioned concrete has been found to be an economically competitive form of construction.  However, unexpected deterioration of post-tensioned concrete structures became a major concern in many countries, despite well-established design and construction practices. As a consequence, significant expenditure had to be diverted from capital works to the management of those structures.

In the United Kingdom a programme of Post-Tensioned concrete bridge Special Inspections (PTSIs) was proposed in 1993 and substantially undertaken in the 1990s/2000s. A review of the results of investigations (Woodward, R 2001) reported that the condition of post-tensioning systems was generally satisfactory although ducts in many bridges contained voids and light corrosion of tendons. Approximately 10 percent of bridges were less satisfactory and needed remedial works. Other bridges were likely to need attention in the future. It was considered that construction detail and practices were the major factors affecting deterioration of post-tensioned concrete bridges, with the integrity of the grouting being of prime importance.

Since the PTSI programme, there has been a reliance on Principal and General Inspections to identify signs of deterioration, but experience has shown that these inspections generally cannot identify the internal condition of the post-tensioning systems, with the result that the level of uncertainty about the condition of ducts, grout and tendons increases with time. The higher risk bridges need monitoring and re-investigation.

In February 2015, ”BD 54/15 Management of post-tensioned concrete bridges” was issued, the Standard providing a process of risk review, risk assessment and risk management for bridges and included advice on activities, such as Special Inspections, monitoring, repairs and strengthening, that would assist bridge managers in making decisions as to when to undertake further investigations and when to use other risk management measures. This Standard has proven to be of significant benefit to bridge managers.

NEW Galvashield XP Anodes Now Available!

April 11, 2019 - On the 20-year anniversary of Galvashield XP, the original embedded galvanic anode for concrete repair, Vector Corrosion Technologies is pleased to announce a redesign of the Galvashield® XP Product Line.

Galvashield XP 2019 Product Trio (April 12, 2019) 150dpi (2).png

Since 1999, the innovative Galvashield® XP Product Line has been protecting structures around the world. The Type 1A embedded galvanic anodes are used to extend the service life of reinforced concrete structures. When connected to the reinforcing steel in concrete repairs, the alkali-activated zinc anodes mitigate the formation of ring anode corrosion in the surrounding chloride-contaminated concrete. The Galvashield® XP Product Line is also used to prevent the initiation of corrosion in new reinforced concrete structures.

Unique features that are found in the Galvashield® XP Product Line include:

  • Low profile, elongated shape fits neatly alongside the reinforcing steel
  • Contractor-friendly Single wire One-and-Done rebar connection
  • CSP-3 concrete surface profile
  • Barfit™ grooved design

The original Galvashield® XP, commonly referred to as the hockey puck due to its short cylindrical shape was available with twin steel connection wires. The redesigned Galvashield® XP Product Line incorporates the contractor-friendly One-and-Done™ single-wire connection for up to 2x times faster installation. Plus, the new low profile, elongated shape allows the embedded anode to fit neatly alongside the reinforcing steel thus reducing the occasional need for additional concrete breakout to accommodate anode placement.

These features mean significantly less labor costs and more efficiency for the contractor’s schedule. The new shape also allows more anodes per box thus reducing shipping costs.

The Galvashield® XP4 and XP2 models have additional benefits, such as the Barfit™ grooved design for secure anode placement and CSP-3 surface profile to promote enhanced mechanical bond with the surrounding repair materials.

Summary of Galvashield® Anode Evaluation

US Bureau of Reclamation Test M82. Standard Protocol to Evaluate the Performance of Corrosion Mitigation Technologies in Concrete Repairs

The need for a protocol to evaluate repair technologies was outlined in a 2006 report by the Strategic Development Council of ACI: “Vision 2020: A Vision for the Concrete Repair, Protection and Strengthening Industry.”

The result of this collaborative effort led to the development of the US Bureau of Reclamation Test M82. The test was designed to measure how various repair methods affect the corrosion rate and durability of concrete structures. Test slabs are constructed such that corrosion can be measured on each reinforcing bar. This allows the total amount of corrosion to be calculated for each slab.

Information on Supplemental Reinforcing in Galvanic Jackets

2018-05-20---News---VCT---Supplemental-Jackets-(Banner).jpg

May 19, 2018 - Structural galvanic jackets incorporate supplemental reinforcement inside the jacket to strengthen a distressed pile that has suffered significant section loss of the primary reinforcement.

For supplemental reinforcement to benefit from a galvanic cathodic protection (GCP) system, the steel must be electrically continuous, and it must be electrically connected to the anode network. In the majority of installations with supplemental reinforcement, conventional uncoated steel is used.

Occasionally, engineers will request that epoxy coated reinforcing be installed inside galvanic jackets for additional strengthening. This is not necessary because the galvanic anode system will easily protect uncoated supplemental reinforcement and it will require unnecessary work to make the epoxy coated reinforcing steel electrically continuous such as removing portions of the coating and welding the bars together.

Uncoated supplemental reinforcement is encased in a highly alkaline cementitious grout inside the jacket. This alkaline environment promotes passivation of the conventional reinforcing, so the additional galvanic current necessary to prevent corrosion initiation of the supplemental reinforcement is minimized.

So the cost-benefit analysis associated with using epoxy-coated steel as supplemental reinforcement in galvanic jackets indicates the use of epoxy-coated supplemental reinforcement is not justified.

Galvanic pile jackets are an excellent choice to protect structures in a corrosive marine environment as well as brackish and freshwater. It is important to select the right pile jacket for the environment.

Vector Expands the Use of Galvashield® One-and-Done™ Single Wire Rebar Connection for Concrete Anodes

January 19, 2018 – Vector Corrosion Technologies is pleased to announce that it is expanding the use of its contractor-friendly One-and-Done™ single wire connection for the attachment of Galvashield® embedded galvanic anodes to reinforcing steel in concrete repairs and new construction.

Galvashield XP is the original galvanic anode for concrete and has been protecting structures around the world for over 20 years.  One of the novel features of the Galvashield XP anode was its twin steel tie wires to make quick and secure connection to reinforcing steel without the need for welding.

Vector first introduced the single wire One-and-Done connection technique in 2015 with the launch of Galvashield XP Compact for the building and parking market.

The three primary features of the Galvashield One-and-Done connection are:

  1. Fast installation – Galvashield anodes are installed up to 2 times faster than the original two-wire method.  This means significantly less labor costs and more efficiency for the contractor’s schedule.
  2. Simple – No special tools are required. 
  3. Lower cost - The new anode design allows more anodes per package reducing shipping cost and reduced packaging waste for disposal.

 

In 2018, Vector will begin to supply Galvashield XPT with the One-and-Done connection and more products will be available in the future.

ACI 562-16: The ACI Concrete Repair Code

The May/June issue of ICRI's Concrete Repair Bulletin included an excellent overview and update on the status of the concrete repair code (Requirements for Assessment, Repair and Rehabilitation, of Existing Concrete Structures) developed by ACI International (ACI).  The Code was developed by ACI Committee 562 to provide a standard for existing concrete assessment and durable repair design.

In 2016, ACI introduced an updated version. ACI 562-16 requires design professionals to satisfy strength requirements and to consider durability in repair design.  ACI 562-16 also includes provisions that are unique to repair such as the evaluation of the interfacial bond of repair materials, repair detailing to minimize the potential for cracking, consideration of the repair sequence, and the interaction of the repaired areas with the non-repaired portions of the structure.

ACI 562-16 also requires consideration of durability in the design of repairs. Ideally, the durability aspects of the repair design will include consideration of the desired service life of the repaired structure.  A primary goal of the durability provisions is to reduce the potential for future deterioration adjacent to the repair areas (anodic ring effect) which can be satisified by the use of Galvashield XP Embedded Galvanic Anodes. 

To assist design professionals in how to use ACI 562-16, ACI/ICRI 562MAN-1611, Guide to the Code for Assessment, Repair, and Rehabilitation of Existing Concrete Structures (Fig. 4) was jointly developed by ACI and ICRI. The guide provides plain language explanation and context to the provisions in the code, including how to work with the IEBC.

VCT Claims Two Awards for Concrete Repair Excellence, October 21, 2015

Vector Corrosion Technologies (VCT) was pleased to be recognized for two recent concrete repair projects at last week's International Concrete Repair Institute (ICRI) 2015 Awards gala at the Fort Worth Hilton. The objective of the ICRI award program is to recognize outstanding concrete repair projects from around the world.  

Strengthening of Grinding Building Slab at Batu Hijau Copper-Gold Mine

2015 ICRI Award of Excellence - Industrial Category

While working at the Batu Hijau Copper-Gold mine in Indonesia, Vector was asked to provide a recommendation for a heavy duty elevated slab that was experiencing major concrete cracking.  Vector's investigation, which included a GPR survey, revealed the concrete reinforcing steel was installed incorrectly.  

Vector devised a concrete slab strengthening plan that utilized carbon fibre reinforced polymer tape (CFRP) placed in slots near the slab surface, verified the strengthening solution in large scale laboratory testing, and implemented the repair with its local partner.

Structural Repair & Protection of Post-tensioned Parking Garage at University of Missouri Hosptials and Clinics

2015 ICRI Award of Merit - Parking Category

A unexpected tendon eruption in a 1986 vintage parking deck lead to a comprehensive evaluation which determined a large percentage of the push through (stuffed) post-tensioned tendons were broken.  A large majority of the post-tensioned tendons also had missing or degraded post-tensioning grease, a problem that was exacerbated by a gutter system that trapped moisture and debris below failed expansion joints. 

As part of a major rehabilitation program, post-tensioning tendons that were treated with Vector’s Post-tech PT Cable Drying system were then injected with corrosion inhibiting grease to provide a long lasting innovative solution.

Corrosion Control Implemented on UK Multi-storey Car Parks, David Simpson 2012

With over 4000 multi-storey car parks in operation, many built without recognising their harsh environmental conditions, the United Kingdom has become a leading user of technologies to address chloride-induced corrosion of reinforced concrete.

Over the past 10 years, corrosion testing has become a standard process in the evaluation of concrete structures (e.g. BRE Digest 444 part 2) and full half-cell corrosion potential mapping is being used more frequently to assess the risk of corrosion, which in practice can vary greatly over the cark park structure.

After identifying the areas of high corrosion risk by corrosion potential testing (such as low cover concrete and high chloride concentrations), a corrosion control strategy can be implemented to target these areas using embedded galvanic anodes, an increasingly utilised technique over the past 12 years.  Galvanic anodes, combined with waterproof coatings which reduce moisture content and create a barrier for future chloride contamination, deliver cost effective corrosion control that will substantially impact the service life of cark parks.
