Maturity Meters and Loggers

The Maturity Method has gained popularity in Canada over the last 10 years. While historically, it was used on mass pours, now we often see it being used on high-rise condo projects looking to quickly strip forms. 

It is based on ASTM C1074 and an alternative to breaking cylinders, while also providing fast results that are more representative of a structure. You can estimate the Compressive Strength of Concrete using the time-temperature history of in-place concrete. A calibration curve is generated for a particular mix-design and then converted using a maturity index (Nurse-Saul or Arrhenius). this provides an estimated in-place concrete strength in real-time.
