## Synopsis Fourier transform infrared (FTIR) spectroscopy has been used as a modern analytical tool to elucidate the structure of urea-formaldehyde (UF) resins. Several low molecular weight condensation products of urea and formaldehyde were synthesized and characterized. Structural differences w
This paper describes the structural changes of C-S-H caused by curing at different relative humidities (R. II.) and temperatures using XRD, 2gSi NMR and thermal analysis. The results show that within the relative humidity range studied (9%-100%), the polymerization of C-S-H does not change, but that
