Calibration prep checklist

Last Updated ·

To begin this process identify who will be responsible for the sample preparation and choose a concrete testing lab for the crushing.

Agree when this will take place with both the testing house and the concrete supplier.

A crushing schedule should be agreed in advance between the contractor and the lab.

The main points to agree in advance include:

  1. Date for samples to be prepared
  2. Who will prepare the samples
  3. Who will install and register the sensors (see article “Installing sensors”)
  4. Whether additional supervision is required
  5. What type of moulds will be used
  6. Who will provide moulds and equipment
  7. Sufficient number of moulds are available
  8. When samples should be transported to lab
  9. Crushing schedule (see article “Crushing guidance”)
  10. When data will be made provided to the contractor

Generally, once the concrete has exceeded its design strength, a curve can be produced (this often occurs between day 7 and 14).

The responsibility of who will fit a curve to the crush data may vary from one country to another. For more information, see related articles below, contact your local representative, or email
