  The water absorption percentage of oolitics sand, which was made by the changing green sand binder and burning temperature, was measured. Bentonite was added to the oolitics sand to make the green sand, and then water absorption percentage was calculated from the relation between the green sand with bentonite and compactability. The oolitics formation was also observed by SEM to investigate the mechanism of water absorption. The results showed that oolitics is formed from thin layers and microporosity which change when the condition of green sand binder and burning temperature are changed. Water absorption was found to occur mainly between the thin layers. As the thin layers closed, the water absorption percentage dropped.
