摘要:The interaction of Si anions with AI sites during the hydration process was observed by NMR, IR and SEM to understand the reaction mechanism of the hydrates formation mixed with oil shale calcined at different temperatures. As the reaction progressed,the coordination of AI (IV, V, and VI) changed almost completely to IV, when mixed with oilshale calcined at 700^(。)C. However, when mixed with oil shale calcined at 400^(。)C, some6-coordination of AI still remained in the hydrates. Under the function of alkaline solutions,which were produced with the hydration of clinker, a certain amount of Si and AI atomsdissolved or hydrolyzed from aluminosilicate, formed geomonomers in solutions, and thenpolycondensed to form networks.
