The influence of SiO2 sources on the formation of 1.1-nm-tobermorite was studied by using quartz, quartz+silicic acid and silicic acid. The mixtures of lime and each SiO2 source with the Ca/Si molar ratio of 0.8 were autoclaved at 180 °C for the specified time under saturated steam pressure, and the variation of structure and composition of the products were examined by X-ray diffraction, analytical-TEM and Si NMR.
