Australian concrete repair association newsletter february 2013

Concrete Connections February 2013 A (belated) Happy New Year to all of our Members. With the new year brings a lot of exciting activities and changes within the association. A number of these are mentioned throughout this Newsletter. One of the main objectives the board has been trying to achieve over the last few years is to extend our reach to all corners of the country and have an active presence in all states and territories. The development and growth of our one day course has certainly helped, however, it is the willingness of corporate members to get involved and support ACRA activities that will make the most difference. It is therefore great to see that we have just had our first corporate member join us from South Australia, Portolesi Structural. Welcome aboard.

We also have another asset owner member join up, Sydney Ports Corporation which continues to show the growing interest and involvement of major asset owners in the association. There are other significant changes happening so please read on for further details and I hope to see as many of our Sydney members at the ACRA awards seminar in a couple of weeks’ time.

-Andrew Dickinson, President.

We are excited to announce that the Association will be having a Special Meeting for members only on the 19th of February 2013 at 2.30pm at the Harbourview Hotel North Sydney (prior to our Awards Seminar). At this Special Meeting we will be voting on a change in the Association name from Australian Concrete Repair Association to the Australasian Concrete Repair Association and if the move is voted in we will continue to keep the acronym ACRA and our members will not be impacted by this name change. The name change will open the Association to a much interested group of companies and individuals living in New Zealand to join in on ACRA developments and sharing knowledge of new techniques and technology. We are looking forward to welcoming our Kiwi neighbours.

As part of this name change, we will be launching our new website which will not only have a more modern and refreshing look but it will be easier for all members and visitors to navigate around. The Association will be adding more documents and information with regards to seminars we hold as well as our newsletters, 1 day technical training course, as weel as our new

Concrete Connections 2 day more advanced technical training course which will be introduced later in 2013 in conjunction with the ACA. Our branding will remain the same so our corporate members will not need to change a thing on their websites and email closures. The board of ACRA and Nicole the Executive Officer will continue our commitment to deliver the best possible membership experience and updates regarding concrete repair methods and technology.

ACRA Awards Seminar – A Review Of Some Of The Award Winning Projects Tuesday 19 February 2013 at 3.30pm – 6.30pm followed by a one hour networking session with drink and canapés Harbourview Hotel, 17 Blue Street, North Sydney The biennial ACRA Awards are seen as the premier awards within the concrete repair industry which highlight some of the more prestigious, complex and outstanding projects to be undertaken over the 2 year period.

The 2012 awards, held in Sydney last October, was an outstanding event with some of the best projects we have seen to yet.

The number of entries and high turn out on the night really reflected the growth of our Association’s membership base and maturity of our industry. The size and type of projects highlighted the process and developments which have been made within the concrete repair industry in Australia.

Overall, 8 excellence awards and 2 merit awards were handed out and we have selected a few of these to be presented, in more detail, in this seminar.

Our program of award winning projects to be discussed include: Project: West Gate Bridge – FRP Strengthening Upgrade BASF Australia Pty Ltd Mr Andrew Sarkady Award: Industrial / Water / Wastewater – Mega Projects Award: Repair Industry Excellence Award for 2012 Project: Taxiway A1 Trail Slab Replacement, Sydney Airport Volumetric Concrete Australia Pty Ltd Mr Robert Piva Award: Small Projects

Concrete Connections Railcorp NSW invited Volumetric Concrete Australia to utilise the new CTS Rapid Set Concrete technology to perform concrete repairs on an existing fractured bridge abutment on the main western line, Liberty Street Newtown. The works were to be performed during a possession of the line for other maintenance works and was to be completed to enable the track to be handed back to Railcorp by 8.30pm on the Sunday evening to enable rolling stock to be re-engaged. The CTS Rapid Set Concrete was to reach stringent performance criteria before the re-opening of the tracks to avoid any disruption to rolling stock and commuter trains which were to resume operation at 8.30pm.

A section of the inner west line was to be closed for maintenance and trackwork providing an opportunity for Railcorp Engineers to seize the opportunity and repair the fractured abutment on the 6 line rail bridge across Liberty Street Newtown.

Railcorp Engineers said the cracked abutment presented no immediate danger but that its replacement would prevent further deterioration and hence the need for more extensive repairs.

The rail line was raised and held in position by hydraulic jacks enabling the fractured section to be removed and replaced with CTS Rapid Set Concrete.

The location of the abutment area was directly below the main bridge beam which meant that concrete had to be pumped in position.

VCA utilized a specially designed CTS Rapid Set Concrete Pump Mix for the project which would meet the stringent requirements of the Railcorp Engineers - a compressive strength of 25MPa and a Flexural Strength of 3.0MPa for the line to be re-opened to rail traffic.

Work began on the removal of the damaged area on the Saturday and continued well into the Sunday of the possession period. CTS Rapid Set Concrete was eventually poured at 3.15pm on the Sunday afternoon during a heavy downpour of rain.

The CTS Rapid Set Concrete was produced via Volumetric Mobile Mixers and pumped approximately 10m via a line concrete pump to the area for repair to allow for placement into the abutment. The placement and finishing was completed by 4.00pm. Concrete testing was performed during the production of the Rapid Set Concrete achieving results of: Compressive strength 2 hrs – 26MPa at 5.15pm 4 hrs – 32.5MPa at 7.15pm

Flexural Strength 2 hrs – 4.2MPa at 5.15pm 4 hrs – 4.9 MPa at 7.15pm

All Concrete test results exceeded the Railcorp Engineers design requirements allowing the track to be reopened on schedule and able to take the loads of the ensuing rail traffic.
