Formation and properties of C-S-H–PEG nano-structures

Results of an investigation of the intercalation potential of polyethylene glycol (PEG) with synthetic and pre-treated C-S-H are reported. The partial intercalation of PEG molecules in the interlayer of C-S-H is discussed. The effective and strong interaction of PEG molecules with the C-S-H surface was shown using XRD, 13C CP and 29Si MAS NMR, and DTGA. The position and character of the 002 low angle XRD peak of C-S-H are affected by drying …
