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:
- Date for samples to be prepared
- Who will prepare the samples
- Who will install and register the sensors (see article “Installing sensors”)
- Whether additional supervision is required
- What type of moulds will be used
- Who will provide moulds and equipment
- Sufficient number of moulds are available
- When samples should be transported to lab
- Crushing schedule (see article “Crushing guidance”)
- 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 email@example.com
