英文摘要

Katoite-bearing rock was revealed in the Hatrurim Basin, Israel. The rock formed by hydration of pyrometamorphic calc-silicate assemblages at temperatures higher than 200 degrees C. The likely age of the hydration process is Miocene, about 6.2 Ma. The main phases of katoite-bearing rock are minerals of the katoite-grossular series, calcium hydrosilicates, fluorapatite and carbonate. Chemistry and mineralogy of katoite-bearing rock resembles belite sulfoaluminate concrete. Studied samples show two sets of porosities, which are low and high, between 22 and 28% and between 29 and 39%, respectively. Increased porosity characterizes non-weathered katoite-bearing samples, whereas decreased porosity is linked to carbonation during weathering. Katoite remained stable in spite of natural alkaline leaching. Although high porosity samples display decreasing strength parameters, most observed rock mechanic characteristics are comparable to modern-day concrete. We suggest that obtained data on natural katoite-bearing rock can simulate the longevity and durability of belite sulfoaluminate concrete.
