Topic
Advances in Carbon Mineralization for Low/Negative Carbon High Performance Construction Materials and Products
About the Seminar
The carbon mineralization in cement-based materials has been widely recognized as one of the most promising technologies for CO2 utilization and storage. The invention of pre-conditioning technology made the commercial carbonation of concrete products possible. The technology has also been used for the performance enhancement of recycled concrete aggregates, conversion of recycled concrete powder into active pozzolanic materials and surface treatment of concrete products.
Thermodynamic models and calculation point out that the polymorph control of calcium carbonate can produce carbonated concrete products consisting of aragonite and give flexural strength more than 50% higher than conventional carbonated concrete products. The commercial production of carbonated concrete products demonstrated very obvious lower production costs and environment benefits with a significant amount of CO2 consumption.
