This page describes the process for entering data for the mass per unit volume tests available in QESTField tests

Overview
The plastic state concrete workflow in QESTField Tests provides a number of options for recording and reporting the Mass per Unit Volume (MPUV) measurement, selected on the Field Data phase of the workflow under the Measured Density Method field. 
The options are summarized here:
| Option | Result |
|---|---|
| None | The MPUV result is neither recorded or reported |
| Enter Final Result | The MPUV result only is recorded directly on the concrete sample in QESTField. This is done in the Measured Density (kg/m³) field directly below the Measured Density Method field in QESTField. It is not reported. Warning Changing from this method of recording the MPUV result to any of the others will clear any data entered in the Measured Density (kg/m³) field. |
| Report Final Result | The MPUV result only is recorded directly on the concrete sample in QESTField. This is done in the Measured Density (kg/m³) field directly below the Measured Density Method field in QESTField. It is also reported. Warning Changing from this method of recording the MPUV result to Enter and Report Full MPUV Test will clear any data entered in the Measured Density (kg/m³) field. |
| Enter and Report full MPUV Test | The Measured Density (kg/m³) field is locked and a new phase, MPUV, is added to the workflow. The data entry for the MPUV test occurs on this new phase. The final result is reported. |
More details on the options are provided in the sections below.
None
This is the default choice and requires no further action.
Enter Final Result
When using this option, the user is presented with a Measured Density (kg/m³) field to complete immediately below the Measured Density Method field.
Field Prompt | Expected Information |
|---|---|
| Measured Density (kg/m³) | The final measured MPUV value. |
The entered value is not reported when this option is used though this can be changed in QESTLab's concrete sample screen later.
Warning
Changing from this method of recording the MPUV result to any of the others will clear any data entered in the Measured Density (kg/m³) field.
Report Final Result
To the user in QESTField, this option appears identical to the Enter Final Result option, presenting the same extra data entry field defined above. Mechanically it is different, however, in that a child test is added to the concrete sample for storing the test result. This ensures that the correct test method is reported for the test result based on the test method selection (i.e. AS or RMS), as shown below:
The result is also stored at the concrete sample level and the reporting flag is set. For this reason, moving from this option to the Enter Final Result option is compatible and data will be retained. The need to use a reduced test for this option, however, means that changing from the Enter Final Result option to Report Final Result will not retain entered data.
Warning
Changing from this method of recording the MPUV result to Enter and Report Full MPUV Test will clear any data entered in the Measured Density (kg/m³) field.
Enter and Report full MPUV Test
When electing to complete a full MPUV test, a new phase is added to the QESTField workflow, named MPUV. This also adds a child test to the concrete sample in QESTLab to contain the measurements and calculations.
This phase of the workflow will present to the user the required fields to enter all of the measurements and observations required to complete an MPUV field measurement and calculate a result. The calculated result will be reported.
The appearance and behavior of the data entry screen will differ based on the selection of the Compaction Method. The Slump (mm) and Number of Strokes per Layer fields will only show if the Compaction Method is of type Rodding.
| Field Prompt | Expected Information |
|---|---|
| Balance | The balance being used to determine the necessary masses, from QESTLab's equipment register. |
| Measure | The unit weight bucket being used to make the mass per unit volume determination, from QESTLab's equipment register. |
| Nominal Aggregate Size (mm) | Imported from the Product Information phase. Used to check that the measure capacity is sufficient per clause 3.1.1 of the test method. A warning will be displayed to the user if:
|
| Capacity of Measure (m³) | The capacity of the unit weight bucket being used. If the selected unit weight bucket contains a calibrated volume then this will be imported and the field will be locked. Otherwise, the field is free entry. |
| Compaction Method | The compaction method used for the MPUV determination. The selection here determines whether some informational fields are shown further down. The entries available in this drop down are populated from QESTLab's Concrete Compaction Method list. |
| Slump (mm) | Only shown if the selected Compaction Method is of type Rodding. Compaction Type The compaction type for a particular method is set in the Concrete Compaction Method QESTLab list. Imported from the Field Data phase if the slump method is used to determine plastic state concrete consistency. Information for the user to make a determination on an appropriate compaction method per Table 1 of the test method. |
| Number of strokes per layer | Only shown if the selected Compaction Method is of type Rodding. Extracted from the Compaction Method if it contains a numeric portion. Information for the user to make a determination on an appropriate compaction method per Table 1 of the test method. A warning will be displayed if the number of strokes per layer is not sufficient per Table 1 of the test method.
|
| Mass of Measure and Glass Plate (kg) | The measurement of mass of the measure and glass plate. |
| Mass of Concrete, Measure and Glass Plate (kg) | The measurement of mass of the measure and the glass plate when filled with concrete. |
| Mass of Concrete (kg) | Calculated difference between the Mass of Concrete, Measure and Glass Plate and Mass of Measure and Glass Plate |
| Mass per Unit Volume of Concrete (kg/m³) | The final calculated result. |
