What's the bolt going in to/hopefully coming out of? If it's an expanding sleeve in a drilled hole in the concrete, then it can probably be done up and then later taken out with an impact driver or impact wrench, or even just a massive socket set with a scaff pole extension, but if it's somehow being set in to wet concrete that would probably be a more permanent thing, with lots more destruction required to remove it.
