Figure 4.4.2.2.1a ( c ) — Temperatures within slabs during ASTM E119 fire tests — semi-lightweight aggregate concrete .
Refer to ACI 216.1 for other graphs showing concrete temperatures for beam reinforcing and other conditions .
For applications with a constant cover dimension over the length of the rebar , the temperature in the concrete will be the same over the entire length of the embedded portion of the post-installed rebar . Figure 1 below shows an example of a roof slab extension with fire exposure on one side and the associated temperature distribution over the bond length of the of the post-installed rebar .
