A calcium monosilicoaluminate hydrate analogous to calcium monosulphoaluminate hydrate has been synthesized at 5 C from a mixture of C3A, calcium hydroxide and amorphous silica. The thin hexagonal plates have a basal d-spacing of 10,0 Å in contrast to the d-spacing of 10,3 Å for the monosulphoaluminate at 5 C. It does not show a clear shift to lower d-spacings like the calcium monosulphoaluminate (10,3 A (5C) to 9,6 X (25C)) when the temperature is raised from 5 C to 25 C; substances with higher d-spacings, i.e. higher than 10,0 Å, are produced on raising the temperature and in some instances C2AH8 (Stratling's compound) and C-S-H hydrates are produced.
