The paper presents a new sampling method for the FTIR analysis, which might be used for the determination of the concrete carbonation progress. The obtained results were compared with the existing drilling method. In the research two self-compacting concretes were used. The tested samples were cubicones and concrete crushed rubble. Samples were kept for 56, 112 and 168 days in the carbonation chamber. To verify the obtained results, thermal analysis – TG/DTA was carried out for samples stored for 168 days in CO2 environment. The achieved results of thermal analysis, confirmed advantages of the proposed sampling method.
