Concrete Construction
Challenge
Cylinder breaks showed a bridge was ready to open, and REBEL® Sensors proved the concrete had not achieved target strength.
Results
Cylinders cured at higher temperatures and achieved target strength for reopening a Bridge in Franklin County, Ohio, on day 1. REBEL® Sensors showed that in-place concrete did not reach this strength until day 3.
Key Product
REBEL® Sensors
About the Project
Strength target for form removal and traffic opening = 3.4K psi
(Per ODOT standards, 85%of f'c. In this case, f'c=4K psi)
A bridge in Franklin County, Ohio
195 yards of reinforced concrete
2 REBEL Sensors were placed in the concrete on the east and west sides of the bridge
The REBEL System was deployed, and the sensors showed that in-place concrete did not reach 3.4K psi until day 3.
The Results
Sensors showed that in-place concrete did not reach this strength until 3 days.
Cylinders cured at higher temperatures achieved target strength for reopening at 1 day.
