摘要: More than 50% of the CO2 emitted during cement production originates from the calcination of limestone. This CO2 is reabsorbed during the life cycle of cement based product such as concrete and mortars in a process called carbonation. The impact that concrete carbonation has in the assessment of CO2 emissions from cement production has not been fully documented. Specifically, there is a lack of knowledge about the carbonation of demolished and crushed concrete. The existing models for calculating carbonation do not take into …
