硅藻土(DE)通过方沸石形成而水热固化。与方沸石形成,强度发展是远远大于硅酸钙水合物(CSH)的形成。NaOH的加入对方沸石的形成有一定的制约作用,这是因为NaOH溶液不仅促进了石英和蒙脱石的溶解,而且还为方沸石的形成提供了Na+。固化温度和时间影响方沸石的形成,在本研究中,在6小时(200 °C)和175 °C(12小时)以上,方沸石似乎很容易形成。水热处理后,方沸石形成后的固体中仍然可以看到硅藻的骨架,而CSH形成后的固体中几乎看不到硅藻的骨架。
Diatomaceous earth (DE) solidifies hydrothermally with analcime formation. With analcime formation, strength development was much greater than that with calcium silicate hydrate (CSH) formation. NaOH addition conditioned analcime formation because NaOH solution not only promoted dissolution of quartz and montmorillonite but also provided Na+to form the analcime. Curing temperature and time affected analcime formation, and, in this study, over 6 h (at 200 °C) and 175 °C (for 12 h), analcime seemed to form readily. After hydrothermal treatment, the skeletons of diatoms can still be seen in the solid after analcime formation but can hardly be found after CSH formation.
