Activate the sensor and tag each one in your SmartRock app by project and section.
Secure the sensor to the rebar in the formwork and pour concrete as usual.
Open the SmartRock app to view concrete strength and temperature data in real-time or remotely using SmartHub.
Under ACI and CSA Standards, a break is considered to be of low compressive strength when an individual strength test (average of two cylinders) is more than 500 psi (3.5 MPa) below the required expected strength. Or, if the averages of all three consecutive sets of tests does not equal or exceed expected strength of the mix design. These nationally accepted specifications do account for normal and expected variability of concrete strength tests. However, if your samples exceed these specified values, more investigation into the cause is required.
