I think they mention the problem might be that doing this effects the strength of the concrete? Maybe they could do it to Roman concrete? I think somebody found the secret to Roman concrete recently didn't they? Heat during the process, and chunks of soft lime in the mix that fill any capillaries created by water getting in the concrete over time?
