QEST Platform 5.7 Documentation
Applies to QESTLab

These articles describe the Concrete Sample Screen (AU) and how to use it to carry out data entry of laboratory results for concrete strength and density tests.

Overview

The Concrete Sample (AU) screen is a complex screen containing several tabs, each of which contain multiple fields for entering information about a concrete sample. Additionally there is an area, the concrete specimen grid, for recording test results for individual specimens.
The concrete specimen grid, and its variations, is at the heart of most of the data entry methods for laboratory concrete test results.
While some fields are always visible, the Test Data, Results and Equipment fields are only shown when the relevant checkboxes are ticked.
Test data can be entered, and edited, here, although it is generally entered elsewhere using an electronic version of the daily worksheet to enter data for all specimens tested that day.
Other test data entry alternatives are QEST Weigh and Measure Station, for physical dimensions and measured density results, and QEST Crush Station for concrete strength results.
Data already in the grid, including that entered as part of a concrete test group - such as specimen Type and Age, can also be changed here.

Notes

Ensure the Show Test Data box is ticked to display the above test data columns.
The test data columns appear between the Prep/Cap and Marks columns.
Note that the fields Dens, Strgth and Age Hours included in this group, are calculated results, not data entry fields.
As shown above, while there are columns that are always present, there are other columns whose appearance depends on the type of specimen selected.
There are also columns whose usage are controlled by 1436123743.

Administration Fields

These fields are applicable to all specimen types.

Field Prompt	Expected Information
Print	Select Yes or No to determine whether the test results for this specimen will appear on the test report. Default = Yes. Result missing on Report? If the Concrete Test Report option Show Checked Results is set to "Yes" and the specimen is not marked as checked, the strength will not appear on the test report.
Charge	Select Yes or No to determine whether the charge for this specimen will be included in the automatic generation of charges for this sample. Default = Yes.
Charge To Plant	Select Yes or No to determine whether this specimen will be charged to the plant instead of the client for this sample group. This requires that the plant has an entry in the QESTLab client list. Default = No. Usage This field is only used by Concrete Producers for internal billing processes and is not applicable to Concrete Testers.
Extern Samp	Select Yes if the specimen was sampled externally. Default = No.
Extern Comp	Select Yes if the specimen was strength tested (compressed) externally. The strength and density results will be able to be directly entered when tested externally. Default = No.
Measured By	A dropdown list to select the name of the person who measured this specimen. The names visible will depend on the rights of the user.
Crushed By	A dropdown list to select the name of the person testing the specimen. The names visible will depend on the rights of the user. Typically this is the person operating the testing machine, when the specimen was tested.
Checked By	A dropdown list to select the name of the person who checked the results for this specimen. The names visible will depend on the rights of the user. Consequences of checking a specimen Checking complete specimens locks them from further changes. Only a supervisor can alter data of a specimen after the results have been checked. If the compression report is signed then the results cannot be altered.

Calculated Fields

These fields are not visible on the screen but are calculated from data entered into the grid and stored in the database. They are typically used when it becomes time to generate reports and can also affect the appearance of values in the specimen grid.

When sufficient raw test data is entered, QESTLab calculates the density and strength result for each specimen and displays these values in the grid.

Additionally, the following are calculated:

Sample average strength/density - The average strength and density results for specimens of a certain type and age are calculated and stored in the database (eg. the average 28 day strength for COMP100 specimens). This is done for each sample.
Pair difference - The difference in strength and density results between two specimens of the same type and age is calculated and stored for each sample.

The sample average and pair difference calculations are done for predetermined ages present in a sample. (Typically, 7, 28, 56 and 90 day). If these differences exceed tolerances (as per AS 1379 for Australia) then the results are highlighted in red.

Additional Fields

Additional Fields are defined as fields that are not visible in the Specimen Grid under the default settings but can be added by the user/customer.

Option

Description

Disable Specimen Test Data After Tested

Restricts who can change test data once the person responsible has been selected.

True

Dimension and weight measurement fields will be locked after the Measured By person is selected unless the logged in user has the general Lab Supervisor permission.

If a Measured By person is selected before all, or any, of the dimensions and weight are entered,
non-supervisors will not be able to add any more values for that specimen.
If a Measured By person is selected for a specimen and the next specimen down the grid has all its measurements and weight entered,
the previous Measured By person will be automatically selected, without warning.
Once selected, the Measure By person can only be changed by a user with the general Lab Supervisor permission.

Load field will be locked after Tested/Crushed By person is selected.

If a Tested/Crushed By person is selected for a specimen and the next specimen down the grid has its load entered,
the previous Tested/Crushed By person will be automatically selected, without warning.
Once selected, the Tested/Crushed By person cannot be changed or removed by a non-supervisor.

False

Fields are not locked.

Using the Concrete Sample (AU) Screen

Entering Specimen Test Data

For concrete strength and measured density testing, the test measurements and results are recorded in the Concrete Specimen Grid.

Pre-existing data

By the time it comes to enter laboratory test data, many of the specimen fields should already have data entered for the specimens. This would normally have been done as part of the sample registration process.

The basic process for entering the specimen test data is as follows:

Step 1.

If required, tick the Show Equipment box to display the Equipment fields in the grid.
Enter equipment items as needed.

Step 2.

It is possible that the test data columns will already be visible in the grid.
If not, tick the Show Test Data box to display the test data columns in the worksheet.

Step 3.

Select the specimen requiring data entry by clicking on its row in the grid.
Click on the data field to enable entry or editing of that value.
Enter the measurements, weight and load results for each specimen.
Moving between cells
- Press Enter or Tab on the keyboard to move from one cell to the next.
- There is no need to click in each cell using the mouse.
The strength and density results for each specimen will be calculated and displayed in the grid.
If a strength result is less than the F'c set on the sample at the Acceptance Age, the result is highlighted in red. (In this example, F'c = 30.0 MPa)

Step 4.

Enter the Test Time for each specimen.
The age in hours will be calculated and automatically displayed.

Step 5.

By default the Failure Mode will typically be set to 'N' (Normal).
If the failure was not normal then use an alternative letter designation as per the 'Failure Mode list'.
For example 'S' for Shear, 'A' for Abnormal, etc.

Step 6.

Select the QESTLab user or users, who measured and crushed the specimen, using the Measured By and Crushed By fields.
