Calcium silicate hydrates are a group of materials belonging to the calcium silicate family. Calcium silicate hydrates are crucial materials in the building industry, especially for thermal insulation and fire-resistant applications. Tobermorite and xonotlite, calcium silicate hydrates, are the most popular materials in the literature due to their structural properties. These material are synthesized by hydrothermal processes. In some publications, several pre-treatments are applied to the starting materials before hydrothermal synthesis. In this thesis, the effects of these processes on different starting materials and how does changing the parameters affect the process are examined. Besides, the main objective of the thesis is to produce the xonotlite phase using recycling materials as economically as possible. Calcium silicate hydrates powders containing approximately 61 wt. % xonotlite was produced with using lime and recycled glass by hydrothermal synthesis method. The obtained product has a mainly fibrous morphology due to the main phase is xonotlite. According to phase analysis, tobermorite, scawtite, and the trace of calcite phases are also present in the general structure. The thermogravimetric analysis demonstrated that approximately 20% loss is observed up to 800˚C (at about that temperature transformation of the xonotlite to the wollastonite phase is occur.). The mass change remained constant between 800˚C and 1200˚C. Calcium silicate powder (obtained by thermal treatments from CSH) was also thermally analyzed and consequently remained stable up to 1200˚C, (the loss was approximately <1%).
