Carbon strips are put up on a basement wall for a crack with an epoxy glue, is there an odor for a long time?

From your handle sounds like you have had a bad time - hopefully you will be happy with the work done, though I would have to say keep a close eye on it, because these carbon fiber "tape" jobs are generally not going to do anything about the problem. In my opinion they just are not really a structural fix for any but the most minor of cracking, and commonly verge on (or into) scam territory, so be prepared to go to plan B if the cracking continues.

If the two components fo the epoxy were mixed in the right proportions, should dry rock-hard within hours - not be at all sticky or tacky feeling - and most of the strong smell (which should be ventilated, expecially if near a source of ignition like furnace or water heater) should dissipate in a day to three. But you will have residual smell, at least in that room, for probably weeks.

Putting a fan on it or cranking up the temperature in that room can accelerate the outgassing and curing - though smell will be stronger if you heat it more. You can also reduce the odor by keeping that room cooler - though the surface itself cannot drop below the required curing temperature of the epoxy, which is commonly in the 55-65 degree range unless a cold-condition epoxy is used (as usually should be on a winter-cold foundation wall).

And I would not have anyone spend a lot of time or sleep in an area where the smell is strong - that stuff does noasty things to brain and nerve cells.
