Start Curing

QEST Platform 5.2 Documentation
Applies to QESTField Tests


This page describes the process of the Start Curing workflow available in QESTField tests.

Contents

Overview

The start curing workflow in QESTField allows for curing information to be added for the specimens created in the field and will be seen when the specimens are received at the laboratory. This workflow can be selected on the Work Order page under the Workflows section when concrete specimens have been added to the work order.

Specimens

The workflow displays curing information about the specimens. Specimens are labelled with their respective Specimen ID, Test Type and Test Date based on the Age of the specimen. The Standard Cure field shows the duration of standard laboratory curing that the specimen(s) will undergo after they have been received in the laboratory prior to testing. The Standard Cure durations are automatically calculated using the Date Received compared to Date Cast.

Field PromptExpected Information
Standard Cure

The duration of standard laboratory curing that the specimen will undergo after being received in the laboratory, prior to testing

The Standard Cure duration are immediately updated after changing the Date Received.

Submitted By

Automatically populated with the user who opened the Start Curing workflow for a concrete sample. This field will be locked once set. 

Condition

Curing condition of the specimen(s). Used for reporting conditions of hardened concrete density tests, if reported. Can be modified later in QESTLab if necessary.

Date Received

Date received in the laboratory for curing.

When the Start Curing workflow is opened, the Date Received is automatically populated.

Time Start Cure

Time the specimen(s) began curing in the laboratory. 

When the Start Curing workflow is opened, the Time Start Cure is automatically populated.

Hours on Site

Time (in hours) the specimen(s) was on site. Calculated from the difference between the Time Moulded on the Concrete Field Data screen and the Time Start Cure from the Start Curing workflow screen. 

Hours on Site is immediately updated when either Date Received or Time Start Cure is modified.

Modify Standard Cure

By pressing any specimen's standard cure button, the duration can be modified. If a duration is manually modified it will no longer be calculated automatically. To restore automatic calculation press the  button that appears after pressing the  button. This change is on a specimen-by-specimen basis.

Non Standard

If the hours on site is not within the standard time, a section is displayed to allow the user to record the reason and minimum and maximum temperatures for each day. 

Field PromptExpected Information
Reason

Reason for non-standard hours on site, populated from the Reason Non Standard list in QESTLab. 

Min./Max. Temperature

Minimum and maximum temperatures for each day the specimen(s) were curing before they were received at the laboratory. These fields will only be shown when the Hours on Site reaches more than 36 hours. 

The number of days shown will depend on the Hours on Site field. 

Shrinkage Specimens (AS 1012.8.4)

The workflow displays curing details for concrete drying shrinkage tests and their specimen sets. Sets are labelled based on the number of specimens present. Information about the curing carried out for the drying shrinkage is recorded here.

Field PromptExpected Information
Externally Prepared

Indicates the specimens were prepared externally.

Use Same Date for All Curing Tasks

For field sampled specimens, checking this checkbox copies the Specimen Receipt Date to the Demould Date and Start Standard Cure Date.

For lab sampled specimens, it copies the Demould Date to the Start Standard Cure Date.

Specimen Receipt Date

This will be initially set to the sample's Date Received.

Specimen Receipt TimeTime the sample was received.
Time On SiteThe duration on site.
Demould DateLocked and copied from the Specimen Receipt Date for field sampled specimens, when Use Same Date for All Tasks is checked.
Demould TimeTime the sample was demoulded
Time in MouldsThe duration from moulding to demoulding.
Start Standard Cure DateLocked and copied from the Demould Date when Use Same Date for All Curing Tasks is checked.
Start Standard Cure TimeTime the standard cure started.
Initial CuringThe duration from moulding to standard moist curing.
Non-Compliance ReasonThe reason why curing was non-compliant. This field is shown when compliance criteria is not met.
Reason
Minimum TemperatureNon-compliance minimum ambient temperature. This field is shown when compliance criteria is not met.
Maximum TemperatureNon-compliance maximum ambient temperature. This field is shown when compliance criteria is not met.

Curing Compliance

Refer to AS 1012.8.4 - Curing Compliance

A warning will also be shown if Initial Curing Conditions are Non-Standard (on the Concrete Field Testing workflow) and Initial Curing is not  24 hours.
