Concrete MaturityConcrete Maturity

Concrete Maturity allows you to track the

increasing strength of concrete as it maturesby monitoring the internal temperature of the

concrete.

Radio Frequency IdentificationRadio Frequency Identification(RFID)(RFID)

RFID allows the user to read and write information

to or from what we refer to as an RFID Tag. Using

radio frequency you eliminate the need to have a

clear line of sight (It will read right through theconcrete).

MATURITY TESTING

Today Tomorrow

The construction

industry relies heavily

on lab/field curedcylinder testing to

determine strength of

curing concrete.

With the advances in

concrete maturity using

established ASTMStandards - in-place

concrete strength can be

determined accurately inreal time.

The use of RFID is a highly innovative

method to take the science of concrete to anew level.

This is precisely why we received the very

prestigious 2004 NOVA award, presented by

The Construction Innovation Forum (CIF).
