Abstract

Nuclear magnetic resonance examination confirms the existence of dimer silicate anions in C₃SH_1.5, suggesting the possible composition Ca₆(Si₂O₇)(OH)₄. Upon being heated, C₃SH_1.5 dehydrates at 520-550 °C with a sharp endothermy and decomposes to CaO plus a calciochondrodite-like phase, which on further heating dissociates, with a gradual weight loss, to α′_L-C₂S with CaO at 800 °C.
