Concrete cancer in cellar caused by water leaking

[attachment=0]image.jpeg[/attachment][attachment=1]image.jpeg[/attachment]Some of the concrete in the cellar ceiling is flaking off, exposing rusting steel (see photo). The areas where this is happening are just below an outside wall. I'm guessing this is due to water leaking from outside. Looking at the mortar at the base of the outside wall, it doesn't seem too bad but there are a few cracks and gaps (photo). So, what should i do? Replace the mortar to stop any more water getting in? And what about the concrete - can i leave it as it is or does this require further treatment?
