Description
Résistance Measurement
Maturity system with ease!
Method which allows, through the temperature monitoring of the concrete, to determine the concrete resistance from any point.
Accurate, efficient and instanteous method.
This method can determine, through the monitoring of the concrete temperature, the degree of progress of chemical reactions corresponding to its hardening.
It allows to know the concrete resistance in situ from the connection degree of progress, resistance determined by the calibration done in laboratory.
This method is based ont the Arrhenius law, which can express the K ratio in the required time to obtain n same degree of hardness at temperature q and 20°C.
This maturity system is in accordance with :
-
the references of the “Projet National CALIBRE” (National STANDARD Project)
-
LCPC technical guide on maturity method
-
standards ASTMC1074-98 (Estimating concrete strength by maturity method)
Trop peu utilisé sur les chantiers, it however brings important improvements at several levels :
-
Security : for delicate operations such as stripping, lifting, tensioning cables…
-
Increased productivity : direct reading of resultts
-
Quality : avoiding the risk of cracking, controlling durability, color,…
