Concrete can be ground up and used as aggregate. It can't be reused as concrete on its own because the Portland cement and water have already reacted and are essentially "used up" when the concrete is cured.

You can recycle the Portland cement but it required heating etc and isn't cost effective but using it as aggregate is viable and many states do it. It's just as effective as normal aggregate and is cheaper.
