QEST Platform 5.2 Documentation
Applies to QESTField Tests

This article describes how a field user can add specimens to a concrete field test using QESTField tests.

Overview

Concrete Field test workflows can be added to Work Orders as described in Adding Field Test Workflows. As part of the Concrete Field Test workflow, users are able to add concrete specimens that will be later transported back to the laboratory for testing.

Specimens Section

The Specimens section for Concrete Field Testing workflows include a Test Group dropdown menu, Add Specimen button as well as a Add Shrinkage Set button.

More details on the options are provided in the sections below.

Test Group

Selecting a test group from the drop down will pre-create specimens at specific ages, types and if they are charged.

Note

The test group drop down is populated from the Concrete Test Groups list in QESTLab. If new test groups are required, these need to be added to the list in QESTLab.

Changing Test Groups

Selecting a different test group to one already selected or selecting a test group when specimens have been manually added will clear all existing specimens and add those defined in the test group. The user will first be warned that this may happen and be given the opportunity to cancel the operation.

Once a test group is selected the Specimens section will automatically populate with the specimen information set in the test group.

Add Specimen

A specimen can be added to the concrete field test by tapping the Add Specimen button.

Note

If adding a specimen where some already exist, it will be added to the end of the test group and the age will be copied from the last existing specimen. If the age of any specimen is changed, the specimen will be re-arranged in order of age.

Each specimen allows data entry to provide details about the specimen and curing times.

Field Prompt	Expected Information
Mould ID	Used to track the Mould number used for casting the specimen.
Type	The test to be performed on the specimen, e.g. COMP100, FLEX150.
Hold	The Hold checkbox is used for specimens that are not going to be tested unless there is a problem discovered with one of the other specimens. When the box is checked the Age - Days, Age - Hours and Test Date fields will be locked and the Age - Days will be set to 999.
Age - Days	The age of the specimen, in days, at which the test must be conducted. Changing the age will change the Test Date.
Age - Hours	The age of the specimen, in hours, at which the test must be conducted. Changing the age will change the Test Date. Important When the Age - Hours field is populated the Age - Days field will be overwritten and locked to show the rounded age in days.
Test Date	The test date for the specimen. Note This is automatically calculated by taking into account the: Date Batched, Time Batched and Date Cast on the Product Information page. The Time Sampled and Time Moulded on the Concrete Field Data page. And the Age - Days and Age - Hours on the Specimens section.
Charge	The Charge checkbox is used to determine whether the charge for this specimen will be included on the automatic generation of charges for this sample. Checking this box add the "Charged" text next to description of the specimen in the Specimens section.

Add Shrinkage Set

A shrinkage set can be added to the concrete field test by tapping the Add Shrinkage Set button.

Each shrinkage set allows data entry to provide details about the specimen and curing times.

Field Prompt	Expected Information
Compaction Method	The compaction method used for the test, populated from the Concrete Compaction Method list in QESTLab.
Mould A	The mould the first specimen was placed in, selected from QESTLab's active Shrinkage Mould equipment register or by free entry.
Mould B	The mould the second specimen was placed in, selected from QESTLab's active Shrinkage Mould equipment register or by free entry.
Mould C	The mould the third specimen was placed in, selected from QESTLab's active Shrinkage Mould equipment register or by free entry.
Initial Curing Conditions	Set the initial curing conditions as standard or non-standard. A technician will set this after considering factors such as humidity, temperature ranges, specimen orientation, etc.
Specimens Require at Least 48 Hours Before Demoulding	Some grades of concrete with compressive strength less than 10MPa at 28 days require the limit to demoulding to be greater than 48 hours.
Non-Compliance Reason	The reason why curing was non-compliant. This field is shown when compliance criteria is not met.
Charge	The Charge checkbox is used to determine whether the charge for the set will be included on the automatic generation of charges for this sample. Checking this box add the "Charged" text next to description of the specimen in the Specimens section.

Removing a Specimen or Shrinkage Set

Specimen(s) and shrinkage sets can be removed by tapping the button when the specimen or shrinkage set is selected.
