Abstract
Aside from carbon capture and storage, CO2 mineralization as a utilization technique appears to be an important lever for lowering cement production emissions. CO2 mineralization is a reversal reaction to clinker production—in an exothermic process, CO2 is bound into stable carbonates. It can be used in a variety of environmentally and economically beneficial ways at various stages of the clinker, cement, and concrete life cycles. The seminar evaluates and discusses these options. The most recent advancements in mineralization technology at Heidelberg materials demonstrate that complete circularity of concrete, including process CO2 emissions from the clinker, can be achieved and the overall related CO2 intensity significantly reduced.
Short bio
Mohsen Ben Haha is the team leader scientific coordination of the Global R&D department of Heidelberg Materials. His research is focusing on multi-phase materials interaction, Building materials’ physical chemistry, transport phenomena in porous materials, chemical attacks investigation, and their consequences on qualitative and quantitative levels. During his career, he had the chance to work in different departments and institutes covering complementary aspects of materials science which enables him to understand different disciplines and thus gives him the opportunity to look at problems from a broad perspective. His interest in cement and concrete technology is tightly linked to its importance to the development of humankind, because the production of Portland cement clinker accounts for about 5-7% of the total manmade CO2 emissions, as the manufacturing of 1-tonne cement clinker generates about 800 kg of CO2.
