Overview

This seminar will provide insights into the repair and rehabilitation of concrete including a contractor’s perspective of the ACRA Research, design and Innovation Award winning project for the M1 motorway between Yatala and Reedy Creek, a case study on the diagnosis and repair of High Rise Buildings and a materials supplier perspective on Innovations in Concrete remediation.

The Concrete Institute of Australia and the Australasian Concrete Repair Association are working together to host this seminar.

Topics

Concrete Mix Design & Concrete Slab Replacements,
M1 Motorway (Pacific Highway) between Reedy Creek and Yatala, Qld

Ian Hampton - Volumetric Concrete Australia
Queensland Transport and Main Roads (Roadtek) identified defective concrete sections on the M1 Motorway that required immediate maintenance (replacement) to ensure that safety is maintained for the M1 users whilst extending the service life of the pavement.
Volumetric Concrete Australia was invited to investigate the use and adoption of CTS Rapid Set Concrete Technology in performing over 200 slab replacements on the M1 Motorway, minimising lane and Motorway closures whilst providing a safe work and customer environment and extending the life of the pavement.

Assessment and Repair of Aging Gold Coast Hi Rise
Shane Roberts - Structural Diagnostics
Design and construction requirements for long-term durability of reinforced concrete structures are well established, with AS 3600 nominating durability design requirements to satisfy a design life of 50 years +/- 20%. Design life is generally defined as the period for which a structure (or structural members) remain fit for purpose with appropriate maintenance.
AS 3600 nominates durability requirements for coastal construction, with further recommendation that where strong prevailing winds or vigorous surf occur higher levels of protection should be considered.
Investigations of high-rise structures along the Gold Coast coastline have shown that significant variation in the levels of deterioration of reinforced concrete structures exists, and that the application of the additional recommendations specified in AS 3600 for coastal environments may require more stringent consideration.
This presentation provides a snapshot of several Gold Coast high-rise structures which have suffered from corrosion of reinforcing steel due to a combination of factors including construction defects, inadequate consideration of durability requirements, or conditions which expedited the corrosion of reinforcing steel.
Following assessment of the cause for deterioration of the structural elements, appropriate repair strategies were considered and implemented through discussion with asset owners.

Accelerated Deterioration of Concrete Structures and Innovations in Concrete Remediation
Hamid Khan, Product Segment Manager-Repairs and Grouts - Fosroc 
Accelerated and premature deterioration of most of the structures during the initial few years of its life cycle is of major concern to the asset owners. The premature deterioration has resulted in reduced service life of the reinforced concrete structures. Many studies report the main causes of this state of dilapidation as weathering, ageing effect, inappropriate design or lack of maintenance and care. In certain environments corrosion of reinforcing steel is one of the most prevalent deterioration processes. Among other factors, water leak is also considered as one of the main causes for the early inception of corrosion and concrete deterioration. There are different causes of reinforced concrete degradation that have different effects on the life of the structure. The resulting varied problems, if remain unattended, can eventually cause larger disasters such as structural failures.
 
The construction industry has recently been witnessing ever-increasing expectations for its design life. The presentation highlights the durability risks to structures and the use of innovative high performance durable repair systems during and after the construction phase. The presentation will look at challenges of premature failure of repaired concrete structures despite the improvement in the repair materials and methods. This session will also encompass the importance of defining the requirements of high service life repair and protection materials.
