A study on the development of CO2 solidification method for recycling autocleaved lightweight concrete (ALC) waste was performed. Milling dust of ALC was used as the starting material for the study. A decrease in the peak intensity of the main tobermorite phase was shown by the X-ray diffraction patterns. No difference in the microstructure and the degree of CO2 solidification at the surface and inside the solidified samples were shown by scanning electron microscopy and optical microscopy.
