Repair Gunite Crack Behind Tiles

concretehole

I had a couple of tiles pop off and I found a crack in the gunite behind them. The crack is about 18 inches long and at one spot had a loose pieces of gunite I could pop out about an inch and a half wide.

I would like to repair the crack before re-installing the new tiles. Wiki says to remove lose pieces, grind away a little at the sides and fill with Portland cement. I wanted to know if anyone had any experience with repairing gunite and if Portland cement is my best option for filling the crack?
