Tuesday, 20 March 2018
5:00 PM - 8:00 PM


TAFE Restaurant
Level 2 - Block C 66 Ernest Street, South Brisbane QLD 4101


Concrete is used in a wide variety of structures and applications in the marine environment. Due to the nature of the exposure condition, there is usually an emphasis on the long term performance of concrete structure. This seminar will provide insights on both design considerations and construction methodologies for concrete structure under such challenging environment.

How to improve the long term performance of reinforced concrete wharf structures in a marine environment
Daniel Anstice, GHD Pty Ltd and Gavin Chadbourn, Port of Brisbane

The Port of Brisbane has a number of wharfs at the mouth of the Brisbane River in Queensland, constructed at intervals since the mid 1970’s. Various approaches have been employed to ensure the long term durability of the wharves beyond the nominal design lives stipulated in design codes; including cement replacements; corrosion inhibiting admixtures; cathodic protection and  coating application. This presentation will discuss the Port’s experiences to date as well as lessons from projects overseas and emerging technologies to improve the durability of marine concrete.

Case studies on previous projects
Ray Crampton, Commercial Marine Group

Ray will present a case study outlining challenges and lessons learned with cold joins for SEQ bridge remedial works.  Then a case study of the Kingsford Smith Drive Grout Bags and how they met the appropriate MPA rating underwater and testing.  Ray’s presentation will also explain the process of testing and trialling grout prior to installation of PileMedic.  For purposes of confidentiality, some project names will not be disclosed.
Ray will be supported by Dean Ballard (Parchem), Tony White (QuakeWrap) and Nic Ayres (Lendlease) to answer technical questions.

The Challenges of Maintaining Structural Durability for Concrete in Marine Environments
Mike Rutherford, Conspectus (Qld) Pty Ltd
The presentation will cover the challenges imposed in maintaining good structural durability for concrete infrastructure located in marine environments where common deterioration mechanisms are present.
Concrete exposed to marine environment deteriorates as a result of the combined effects of the chemical actions of seawater on cement hydration products, alkali-aggregate expansion, the pressure of crystalising salts within the concrete, the corrosion of embedded steel in reinforced or prestressed members, physical erosion due to tidal and wave exposure and carbonation of the concrete, all of which promote concrete cracking, spalling and delamination.
Case histories will be presented relating to concrete remediation and protection projects within the marine environment.
