The conditions made it extremely difficult, if not unrealistic, for field-cured cylinders to capture the accurate in-place strength results required. With a tight schedule to maintain, the time-consuming process of cylinder break tests was not meeting our needs, nor the building owners'.

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.

Data History
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.
“There's no doubt that SmartRock saves an unbelievable amount of time and money for the contractor — and takes the maturity method to the next level.”

“For me personally, the project I go to, whether it's a bridge, a low-rise construction, or a high-rise building, if I'm pouring concrete, I'm going to seriously think about using this technology [SmartRock] rather than field cures — just because I have seen the advantages first hand.”
Shawn Kitt, Superintendent, PCL Construction |
“Depending on how many phases and the number of pours, you can save days on some jobs and weeks on others [using SmartRock].”

“Once the SmartRock sensors were installed, we didn't look back...”
