# Concrete Material Properties

How to create, apply, and auto-update concrete beam material definitions using the Edit Design Properties menu.

Concrete beam material properties are created and managed using the "Edit Design Properties" button on the ribbon bar:

![](https://4249100372-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgHVzpA9PT0VcuNGp6j39%2Fuploads%2Fgit-blob-5802a71817cde3fe93f98f1f02445557d083f9cc%2Fclip0712.png?alt=media)

When triggered from the ribbon button, the menu will load in the lower right corner of the Revit UI:

![](https://4249100372-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgHVzpA9PT0VcuNGp6j39%2Fuploads%2Fgit-blob-c8ad53434071e4730622dec6b1a040ceb6ed4bf5%2Fclip0762.png?alt=media)

This menu also contains tabs for managing other design properties, including beam design rules and rebar material properties. For more detail on the use of these tabs, refer to [Beam Design Rules](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules.md) and [Rebar Material Properties](/efr-user-manual/calculation-types/working-with-beam-calculations/concrete-beam-calculations25/rebar-material-properties.md).

Concrete material definitions are found on the second tab of the menu:

![](https://4249100372-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgHVzpA9PT0VcuNGp6j39%2Fuploads%2Fgit-blob-3ea08981f9654e903a786472c77f4f86dc1ac126%2Fclip0763.png?alt=media)

In a new project where no previous definition editing has been performed by the users, the menu will be populated automatically with a set of 5 sample concrete materials (3 normal weight and 2 lightweight) which are stored in the `.rvt` file by default. Use of these default materials is optional. They may be removed or edited/renamed as desired by the user. Even though they exist in the Revit model, the default materials will not influence the behavior of concrete beam calculations unless manually applied to specific beam elements by the user.

Users should note that the basic mechanics are the same for all design definition tabs found in this menu. The processes to "Apply", "Modify", "Add", "Delete", or "Erase from Elements" do not vary from tab to tab. Regardless of which definition tab is being used, users may reference the following sections for guidance about managing design definitions:

[Applying Rules to Elements](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/applying-rules.md)

[Modifying Rules](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/modifying-rules.md)

[Adding Rule Definitions to a Project](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/adding-new-rules.md)

[Deleting Rule Definitions from a Project](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/removing-rules.md)

[Erasing Rule Definitions From Elements](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/erasing-rules-from-elements.md)

[Navigating Rule Definitions](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/navigating-rule-definitions.md)

In addition to the ability to edit each cell of each definition manually, the buttons in the lower right corner of the menu also allow the user to auto-update certain aspects of the material definition per industry-standard methods. This prevents any need for time consuming manual re-calculation of material properties in the event that critical properties such as compressive strength or unit weight are altered. Using any one of these buttons while a definition row is selected in the table will cause the corresponding value in the selected row to update automatically. The "Saved?" check box will then be cleared to indicate that the row has unsaved changes:

![](https://4249100372-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgHVzpA9PT0VcuNGp6j39%2Fuploads%2Fgit-blob-2bc66c25e4c2a77425f4f74425c6d17d40ea523e%2Fclip0765.png?alt=media)

![](https://4249100372-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgHVzpA9PT0VcuNGp6j39%2Fuploads%2Fgit-blob-0475caeb4e2c4f07f20cc840db8a05ebd06fd80a%2Fclip0766.png?alt=media)

There are no default concrete and rebar material properties applied to elements automatically. They must be assigned to elements manually via the process outlined above. Any attempt to launch a concrete beam calculation when no concrete material has been applied will be halted with a warning:

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enercalc.com/efr-user-manual/calculation-types/working-with-beam-calculations/concrete-beam-calculations25/concrete-material-properties.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
