how to make material2 tabs to use full page size

I want to create tab group having two tabs. Tab group should use the full page size and the individual tab should get equal width. Following is code that I am using

<md-tab-group fxFlexFill>
    <md-tab>
        <ng-template md-tab-label>
            <md-icon>description</md-icon> Content Privileges
        </ng-template>
        Content Privileges
    </md-tab>
    <md-tab>
        <ng-template md-tab-label>
            <md-icon>flash_on</md-icon> Application Privileges
        </ng-template>
        Application Privileges
    </md-tab>
</md-tab-group>

And here is the output of above

Tabs are not using the full width. And label icon and text is not aligned.

How can I do that?
