Abstract

Continuous streaks parallel to a* on electron diffraction patterns
of 3.15 A C-S-H phase reveal stacking disorder. The majority
of crystals exhibit streaks only for k + 1 = 2 n (k = 2 n + 1
and 1 = 2 n + 1) corresponding to an A-centered po.lytype. Streaks
at both k + 1 = 2n and k + 1 = 2 n + 1 indicate an .intergrowth
of A oo 22 and P oo 21 in various proportions. Co-exiisting xonotlite
predominantly has P oo 21 stacking type.
