Abstract:
Portland cement as the main constituent of conventional concrete is the most widely used cementitious material in the construction industry. But Portland cement production has major environmental disadvantages, including high energy consumption and carbon dioxide (CO۲) emissions. So that production of Portland cement is accounted for ۷ to ۱۰% of global CO۲ emissions. Considering the amount of Portland cement production and CO۲ emissions in Iran, it can be concluded that Iran is facing environmental problems caused by cement production. Hence, various CO۲ emissions mitigation strategies of Iranian cement industry have been evaluated in this study. This research work applied Analytical Hierarchy Process (AHP) method to evaluate and prioritize mitigation strategies. The obtained results showed that among the ۱۶ strategies studied, clinker substitution (blended cement) and production of low carbon cements such as geopolymer cement were recognized as the most important strategies to reduce CO۲ emissions in the Iranian cement industry.
