Reconstruction of the distribution of (semi-)amorphous phases. (Top) Zoom on the low-2 [theta]

zone to highlight the effect of the C-S-H phase on the diffraction profile. (Botton left) Integrated intensities of this band are used to obtain the spatial distribution of C-S-H. (Bottom right) A similar approach, fitting the higher 2 [theta]

band due to the capillary glass scattering, is used to reconstruct the shape of the capillary as a reliability test.
