Abstract:
A technology was developed to produce high strength building materials by treating slags with CO2 at elevated pressure (20 bar) and temperature (140°C) without addition of binders. The carbonated materials can compete with concrete products (C35/C45) and have excellent environmental and technical properties. The materials have the additional advantage of sequestering 180-200 g CO2/kg slag. The process makes use of a unique combination of existing technologies commonly used in the construction industry. Building of a pilot installation for treatment of 10.000 ton of slag per year is planned for the near future.
