Effect of dehydration time on pore distribution of metakaolin-based geopolymer was studied in this research. Geopolymer samples were cured at 60°C for 1 to 4 days. After that, the sample was taken out and placed at room temperature until the 14th day, and the samples were cut about 3 mm from the bottom, and the pore distribution was measured by SEM.
