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.

Chloride Extraction Technology Recognized by ICRI

At the International Concrete Repair Institute 2016 award program, the Historic Malpaso Creek Bridge rehabilitation project was recognized with an Award of Merit in the Historic Structures category.  VP of Business Development Eliseo Conciatori, accepted the award on behalf of the project team Caltrans (Owner), Truesdale (GC), Vector Construction (Corrosion Subcontractor), and Vector Corrosion Technologies (Technology Provider).

The Historic Malpaso Creek Bridge, is an open spandrel reinforced concrete parabolic single span arch bridge.  Situated adjacent to California’s Pacific Ocean, the Malpaso Creek Bridge has been subjected to airborne chloride exposure for 80 years.  The Malpaso Creek Bridge’s reinforced concrete spandrel columns, arch-spans, and struts were treated with Norcure Electrochemical Chloride Extraction (ECE).   No permanent system is left in place and the bridge maintains its original appearance, a key benefit for historic bridge preservation.

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.

2014 ICRI Award of Excellence Winner

Vector Corrosion Technologies was the recent recipient of the 2014 Award of Excellence for the Concrete Repair and Corrosion Mitigation of Disraeli Bridges Concrete Piers by the International Concrete Repair Institute. The City of Winnipeg utilized an innovative Design-Build-Finance-Maintain contract to address corrosion damaged concrete bridges on the Disraeli Freeway. The project utilized Norcure electrochemical chloride extraction to passivate active corrosion on land-based concrete piers and Galvanode ASZ+ humectant activated metallized zinc anode to control corrosion galvanically on two water-based concrete piers.

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.
