Title: Mineral carbonation – a CO2 utilization technology for cement and concrete

Mineral carbonation as a means to produce construction materials is an innovative and rapidly developing field that is expanding into various construction material application domains. The conversion of CO2 into solid, stable mineral carbonates is considered to be a promising and potentially viable way to reduce, store and use carbon emissions. Mineral carbonation usually is a slow process, yet can be accelerated in various ways and applied to a wide range of precursors. This has led to a multitude of processes (wet, moist, dry, supercritical,…) and applications under investigation and development.

In this webinar, the basic concepts and principles of mineral carbonation are introduced and recent advances in mineral carbonation processes and products are introduced using examples from recent R&D projects. Mineral carbonation precursors are discussed, with focus on recycled resources such as steel slags, energy and incineration ashes, and concrete demolition waste. On a more general note, it will be stressed that the expanding field of mineral carbonation requires sharing experiences, understanding and best practices to build a common knowledge base and disseminate the current state-of-the-art. In conjunction, we highlight the activities of RILEM TC MCP as regards establishing terminology and material characterisation methods while addressing knowledge gaps on reliable process impact data and assessments.
