Cracking in concrete continues to be an ongoing topic of consideration from many industry practitioners. Even with readily available information and resources on cracking and placement, it is still a major issue for all stakeholders in concrete structures.

This event is designed for all members of the concrete construction industry - asset owners, Engineers, Architects, builders, concrete placers, form workers, steel fixers, PT companies and pre-mixed concrete manufacturers. 
Please join us, and be involved in what will prove to be a valuable evening covering:
  • Back to basics - How to get it right the first time to avoid costly mistakes in the future.
  • What cracking commonly occurs in concrete, and what causes these cracks to appear.
  • What steps you can take immediately to avoid unplanned cracks in your next job.
  • An open forum and discussion on why we keep having cracking issues? How can we, as an industry, work towards reducing or removing these issues in our market?
Walk away with some practical steps to reduce your cracking risks immediately, and a greater understanding of the types of cracking in concrete, why they occur and construction quality.

Gordon Chirgwin
Previously Roads & Maritime Services


Industry expert, Mr Gordon Chirgwin will be presenting "Industry Case Studies" - Providing insight based on his extensive career at Roads and Maritime Services. Gordon will be touching on several projects that are important to this region, and the wider concrete construction community.

Gordon Chirgwin is a Civil and Structural Engineer with over 40 years experience.  He worked for the NSW state road authority in a wide range of roles, including construction and technical advice.  He studied Concrete Materials and Behaviour under Professor Harold Roper and the Late Professor Denison Campbell-Allen as a major part of his Degree of Master of Engineering. 

He has authored several papers on concrete, was the primary driver behind the re-writing of RTA B80, Concrete Works for Bridges, and the associated training program (now the RMS Grey Card for Bridge Concrete). For 16 years, Gordon also advised on durability and construction issues for bridges and related structures for RTA, and authorised technical guidelines and policies on RTA bridgeworks.

"Concrete Cracking & Placement Procedures"
Mr Michael van Koeverden

Director, CQT Services

Why are some structures more prone to cracks than others? What effect does pumping of concrete have on unplanned cracks? Why is placement slump, bleed rate/moisture loss and curing of concrete so important to avoid cracks? What happens wen it all goes wrong and we end up in court? Risk needs to be understood by all parties, and is covered, to minimise your input into a costly cracking issue. 

Concrete can be designed for appropriate crack control and there is considerable information available to assist with this. Major crack types can be identified and strategies put in place to prevent future cracks.

Designers, builders, concreters, and suppliers all have a role to play in controlling concrete cracking and this is an event that should not be missed to avoid future cracks where you don’t want them, and to understand the practicalities of what actually happens on site and what needs to happen.

There will be an open forum and panel discussion including both Gordon Chirgwin and Michael van Koeverden following the presentations.
