Nuclear magnetic resonance examination confirms the existence of dimer silicate anions in C3SH1.5, suggesting the possible composition Ca6(Si2O7)(OH)4. Upon being heated, C3SH1.5 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.
