Carbon reinforced concrete material cycle

Carbon reinforced concrete construction involves a closed material cycle. In the very extensive investigations along the entire material cycle, until now no respirable fibre fragments within the size range of the WHO definition have been found for the carbon used in carbon reinforced concrete.
