This ancient technique could help make new buildings more sustainable. The key is tiny white lumps called lime clasts, which are not found in modern concrete. Previously, they were dismissed as sloppy mixing but scientists have found they fulfil a vital role. When cracks appear in the concrete due to weathering, the lime clasts react with water to make a calcium solution which flows into the cracks and crystallizes again. ‘Healing’ any damage before it spreads. #wef23 #science #technology #concrete #colosseum #pantheon #building #emissions #construction
