Carbonation of ALC panels progresses simultaneously throughout the whole section. Even with ceramic tiles laid on one side of the panel, ALC is carbonated to the back of the tiles by CO2 penetration from the other side. In this research, tiled ALC panels were subjected to accelerated carbonation followed by bond strength testing between ALC and tiling. As a result, it was found that carbonation of ALC does not directly cause tile spalling up to a carbonation degree of 89%.
