Analyses of 225 particles of C‐S‐H in ground and redispersed pastes of β‐Ca 2 SiO 4 hydrated for 7 days to 22 years gave a mean Ca/Si ratio of 1.38 with a range of 1.1 to 1.6. The mean Ca/Si ratio is substantially constant over the period studied and is lower than that of 1.52 found by the same method for Ca 3 SiO 5 pastes.
