Hydrothermal transformation of tobermorite gel to 10 A tobermorite
Tobermorite gel, formed by hydrothermal reaction of silica and lime, is transformed either into 'Z' phase if the quantity of lime is less than 37 % or into 10 A.U. tobermorite if the quantity of lime is between 37 % and 42 %. The sheets of tobermorite gel are progressively ordered in a direction perpendicular to their plane in a turbostratic way to form 'Z' phase. The order is correct in the plane but there is rotations with different angles between planes (large variations of a and b parameters occur). On the contrary, the sheets of tobermorite gel are ordered in a perfect way during the formation of the 10 A. U. tobermorite and without noticeable modification of parameters a and b. The 10 A. U. toberrnorite is stable in the presence of gyrolite, whereas 'Z' phase is metastable.
