Slurries of quartz, slaked lime, and sodium dihydrogen phosphate containing hydrochloric acid as the solvent were hydrothermally treated to prepare tobermorite incorporating phosphate species. X-ray diffraction and X-ray fluorescence analyses showed that tobermorite with a trace of phosphate species formed after the treatment. The sizes of plate-like tobermorite depended on the sodium phosphate additive and solvent. There were almost no effects observed of the additive and solvent on the morphology of tobermorite. Sodium and/or phosphate species promoted the transformation from calcium silicate hydrate gel as the precursor to tobermorite. Phosphate species were introduced into the tobermorite structure, resulting in the distortion of its structure.
