In this paper. the carbonation depths of glazed hollow bead insulation concrete (GHBC) and normal concrete (NC) at different carbonation ages are tested. The microstructure of GHBC and NC before and after carbonation were observed and compared by mercury intrusion porosimetry (MIP). energy dispersive spectrometer (EDS). https://www.markbroyard.com/best-flash-pp-aluminum-lotion-pump-supply-amazing-save/
