Carbonation Potential of Cementitious Structures in Service and Post-Demolition: A Review

The construction sector is responsible for a great environmental impact. cement industry, which included in this sector, emits about 650 to 800 kg of CO2 per each tonne produced, being one the most polluting industries terms greenhouse gas emissions. manufacturing process releases 7% total worldwide However, concrete and cement-based materials present uptake potential during their service life post-demolition through carbonation processes. reactions rate depends on several factors, namely type content cement, porosity concrete, temperature, relative humidity exposure conditions area. Therefore, estimate capture its cycle not straightforward calculation. Some studies have been developed using different methodologies order evaluate cementitious elements post-demolition. This paper reviews documented approaches that quantify over time, summarizing assumptions adopted previous work. Overall, it was concluded part emissions released production are reabsorbed by products cycle, partially offsets impact reduces footprint industry.
