Structural intergity of concrete after a fire
(OP)
Will heat generated from a house fire change the structural properties of the concrete significantly enough to cause concern?

Sometimes there has been little or no effect. One of the most common problems is that when the fire is extinguished with water, the sudden cooling cause the concrete to crack.
Concrete is fairly resistant to fire/thermal events. It takes a sustained elevated temperature (800C for 4+ hours)to serious degrade the integrity of the cement particle bond. Otherwise the effects are mostly physical cracking and carbonation of the surface.

Note that concrete repair over significant areas is difficult, and is not as reliable compared to the original undisturbed conditions. It could lead to weakened service performance, but may or may not be a vital concern on structural performance.
Each fire has its distinct characteristics, be prudent, exam and evaluate accordingly.

There are more papers out there, google it.
