Concrete Maturity

 

 

IK Sensor

 

Description

An "IK" sensor measures the maturity of concrete as it hardens.

The Concrete Maturity (IK) sensor consists of a miniature datalogger with an embedded temperature sensor, battery and processor. The temperature history of the surrounding concrete is tracked and used to calculate the strength "maturity" of the concrete.

 

Manufacturer

IK sensors: intelliRock Maturity Logger, manufactured by Engius.

 

Location

IK sensors are located at various depths in the concrete surface layer.

 

Current Status

IK sensors are only downloaded early in the life of a test cell. Only recently installed IK are still functional.

 

MnROAD Database Tables

Data has been collected during the early life of several test cells. Data has not yet been loaded into the MnROAD database as of March 2011. Once processed it will be loaded into the database table named: MNR.IK_VALUES.
