Visit with us at the ACI Sprint 2010 convention in Chicago March 21st - 25th! Jim Mikulanec and Tom Luby will be attending and you can catch them during the week in the Exhibit area. They would be happy to discuss concrete maturity or temperature profiling technology and share their experience from the field.
In addition, Tom Luby, P.E. will be presenting ways to use concrete maturity to reduce material costs (Monday at 3pm). Bidding and starting the job with multiple approved and calibrated mix designs can really make a difference on your bottom line! He'll show you how it's being done in the northestern US. For continuing education credits, use the session attendance tracking form located at the back of the program book provided at the convention. This form can be submitted to state boards that allow self-reporting of Continuing Education activities as evidence of participation. In most cases, 1 contact hour is equal to 1 Professional Development Hour (PDH). Check with your state board for acceptance criteria.

If you would like to schedule a time to chat with Jim or Tom, you can get their contact information here.
We'll see you there!
Clayco, Inc. and concrete sub Concrete Strategies, Inc. recently completed a 2 story parking garage for online brokerage firm Scottrade in St. Louis, Missouri. Information from intelliRock concrete maturity sensors was used to time critical workflow activities such as post tensioning.

Right: Post tension cables which were stressed in two stages, 1600 PSI and 3000 PSI
Concrete Strategies VP, Barclay Gebel explains “For crack controlling reasons we stressed the PT cables in two stages. The first stage was when the concrete achieved 1600 psi and the second stage was 3000 psi. We use intelliRock to determine when to do the stressing.”
Project engineer Curt Costello continues, ”We were able to determine when different crews would come in to start stripping forms and preparing the PT cables for stressing. Once the strengths were met, we were able to stress the cables without losing much time. This was because we were able to anticipate concrete strengths based on information from intelliRock.”
The graph above is an example of the information available to Concrete Strategies in real-time at the jobsite. intelliRock sensors evaluated the concrete’s maturity every 60 seconds. The maturity reading could be correlated to a concrete strength using a calibration curve for the mix design. This gave Concrete Strategies up-to-the-minute concrete strength values.

I would like to thank everyone that stopped by to meet us at WOC 2010! Although the overall attendance was down significantly, we were very pleased to find a lot of our customers at the show. It was a real pleasure meeting everyone and visiting with old friends.
I also want to pass along a special THANK YOU to the folks on the Audubon Bridge project for allowing us to show live readings using intelliRock LIVE during the exhibition. Getting live readings over the web and to your smart phone is an exciting technology, but having demos using live readings from the Audubon Bridge was the icing on the cake. Thank you gentlemen!
