How to add a concrete mix (maturity calibration) for strength predictions

For Maturix to be able to estimate the concrete strength, you need to add the strength-maturity relationship (maturity calibration) of the concrete mix design(s) used for the project.

Adding the maturity calibration can be done in two ways, which is depending on your user role:

1. By adding it to the Concrete Database and then adding it to a project (Administrators and Project Managers)
2. By adding it directly on the project (Controllers and Supervisors)

The first method enables you to add the calibration data to several projects, but it is required that you are part of an organization – and not just invited to a project.

How to add a concrete mix to the Concrete Database and then to a project

1. Click on Concrete Database in the menu
2. Click on Add concrete mix in the top right corner
3. Fill out the pop-up box
   1. Enter the Concrete Name
   2. Choose the Maturity Function
   3. Add the strength-maturity relationship (see ASTM C1074) under Data Points
   4. Change the custom maturity function settings
      • Arrhenius: Activation energy, increment energy and specified temperature
      • Nurse-Saul: Datum Temperature
      • Dutch Weighted Maturity: A-value and C-value
4. Click on Save concrete mix

Now you have added it to the Concrete Database. Then you just need to add it to a project:

1. Click on the Assign concretes to Project in the top right corner

2. In the pop-up box, select the Project and the Concretes that you want to add to it and Save the changes.

The concrete mix has now been added to the project and can be chosen when creating a cast for strength prediction.

How to add a concrete mix to a project

If you are not part of an organization, but have been invited to a project, you can add the maturity calibration by following these steps:

1. Click on Projects and open the project you want to add a concrete mix to
2. Click on Concrete Mixes in the menu
3. Click on Add concrete mix in the top right corner
4. Fill out the pop-up box
   1. Enter the Concrete Name
   2. Choose the Maturity Function
   3. Add the strength-maturity relationship (see ASTM C1074) under Data Points
   4. Change the custom maturity function settings
      • Arrhenius: Activation energy, increment energy and specified temperature
      • Nurse-Saul: Datum Temperature
      • Dutch Weighted Maturity: A-value and C-value
5. Click on Save concrete mix
