Applies to QEST Web App

The Making and Curing worksheet comes in several different versions. This article explains how the test method BS EN 12390-2:2019 has been implemented as a Making and Curing worksheet.

Contents

Overview

The actual details of Making and Curing worksheets change with the testing jurisdiction and test method that applies to the specimens. Additionally when present in the embedded form, the contents of worksheets can also vary depending on the worksheet in which they are embedded. However, the general purpose of the different versions remains the same and there are common features.

This article provides information on using the Making and Curing embedded worksheet for test method BS EN 12390-2:2019, when specimens have been moulded from fresh concrete.

  • This worksheet contains a wide grid for some values.

  • When using tablet devices, landscape orientation will allow more of the grid to be shown at once.

 

Embedded Versions

There are two different versions of the BS EN 12390-2:2019 embedded worksheet:

  • As part of a Set, for example as in the Sample Document page.

  • For Concrete Specimen Receipt page.

General Description

The following commonalities occur between the versions of the BS EN worksheet.

  • Each embedded worksheet has a link provided to access the full version of the Making and Curing worksheet.

  • The embedded worksheet usually has two parts:

    • A general information area;

    • A grid for specimen set or curing information.

The Calibrated moulds used checkbox controls how the Mould Id fields, in the specimen curing area, work. For details refer to Mould ID, below.

There are no visible results, however, to see what happens in the background, refer here for more information .

If the checkbox is unticked after being ticked, the field, Site Cured Specimen Storage Location, is removed from the general information area.

The only visible result is that an extra field, Site Cured Specimen Storage Location, is added to the general information area. To see what happens in the background, go here.

Mould ID

If the Calibrated Moulds Used checkbox:

  • Has been ticked, the field will be a dropdown list of all available concrete specimen molds;

  • Has not been ticked, the field will be a free entry text field.

When changing from “ticked” to “unticked” any values present in the Mould ID fields will be retained and made free entry.

When changing from “unticked” to “ticked”, if a Mould ID has been entered for any specimen, a confirmation dialog will be shown to the user warning that the field will be cleared, if the action is completed.

If Made by Others is ticked, the field will be a free entry text field.

If a colored (not grey) border appears around the field after a selection has been made, it usually means that the selected mold does not have a current calibration that covers the work date.

 

For Concrete Specimen Receipt Page

Some additional functionality is present that is not present in the Set version as, for example, found on the Concrete Sample worksheet.

Initial Curing Temperature Range

The standard requires that the initial curing temperature range be recorded and, optionally, reported.

Most of the time, this temperature is recorded by automated logging equipment and the records from these are kept separately to the records pertaining to the specimens themselves. As a result, the recording of this information, as part of making the specimens, is optional.

Specimen Information

Specimen ID

Individual specimen IDs are links that navigate to the specimen level version of the Making and Curing worksheet. However, these do not contain much useful data because they are only used to house the logic necessary to calculate the specimen's curing duration.

  • The specimen's:

    • Curing Start value is set to the value of the Laboratory Curing Started field.

    • Curing Type value is set to “Laboratory”

    • Curing End value is set to the date and time the laboratory testing is carried out.

  • If the checkbox is unticked after being ticked, in addition to the above, the field, Site Cured Specimen Storage Location, is removed from the general information area.

  • The specimen's:

    • Curing Start value is set to the value of the Date and Time Specimens Made field.

    • Curing Type value is set to “Site”

  • A date/time picker is provided to record the Curing End value.

  • An extra field, Site Cured Specimen Storage Location, is added to the general information area.

Mould ID

If the Calibrated Moulds Used checkbox:

  • Has been ticked, the field will be a dropdown list of all available concrete specimen molds;

  • Has not been ticked, the field will be a free entry text field.

When changing from “ticked” to “unticked” any values present in the Mould ID fields will be retained and made free entry.

When changing from “unticked” to “ticked”, if a Mould ID has been entered for any specimen, a confirmation dialog will be shown to the user warning that the field will be cleared, if the action is completed.

If Made by Others is ticked, the field will be a free entry text field.

If a colored (not grey) border appears around the field after a selection has been made, it usually means that the selected mold does not have a current calibration that covers the work date.

Curing Started

As discussed above, the value of this field is controlled by the status of the Site Cured checkbox.

Once this field has a value, the set name will no longer appear in the Set dropdown list with the result that the set cannot be accessed by the Concrete Specimen Receipt process again.
