Concrete Construction

Challenge

The contractor relied on 42-day core samples for payment, when paving California I-10.

Results

28-day cylinder was only 5K psi. REBEL® Sensors showed that concrete reached final strength at 30 days instead of 42 days.

About the Project

The contractor relied on 42-day core samples for payment

Paving California I-10

56-day Target Strength = 5.5K psi

3 REBEL® Sensors placed in concrete

Cylinders taken at 1, 4, 7, 14, 28 and 42 days

The REBEL System was deployed, and real-time strength data was provided to prove the results were acceptable and that the concrete in the paving project reached final strength at 30 days.

The Results

28-day Clylinder was only = 5K PSI

REBEL® Sensor Data Real-Time Strength 30-day = 5.5K psi

Final Strength = Payment
