The first thing you need to do is determine how deep it goes into the column. If more than a superficial depth, you have an issue that will require more extensive repair. If only superficial, then a high quality repair mortar can be used to repair the blemish.

Looks like you also have a little bit of scaling near the top of the concrete pour. Chip away any loose concrete flakes and replace with the repair mortar.

Honeycombing repair procedures can be found on the net. This involves drilling and injecting epoxy, followed by
things like Xypex patch and plug systems.
Xypex would be a good place to start.
