- Abstract
Calcium silicate is one of the cement components that can be synthesized by using calcium oxide (CaO) and silica (SiO2) derived from limestone and sand, respectively. The precursors used to synthesize calcium silicate are extracted by mining which may damage the environment. The purpose of this study was to synthesize calcium silicate compounds by replacing limestone and clay with organic materials to reduce environmental problems.
Potential precursors to the synthesis of calcium silicate compounds are broiler chicken eggshells and green sugarcane wastes. Calcined broiler chicken eggshells contain mainly solid calcium oxide (80% of CaO), and the calcined bagasse contains 66.70% of silica (SiO2). In this study, broiler chicken eggshells were calcined at 800 ℃ for 10 h to decompose calcium carbonate (CaCO3) to calcium oxide (CaO), while bagasse was calcined at 800 ℃ for 4 h to produce silica (SiO2).
Calcium silicate was synthesized using the solid-state reaction method of stoichimetric mixtures of calcium oxide (CaO) dan silica (SiO2) at a varied temperature of 950 ℃, 1000 ℃, and 1050 ℃. The calcined products were characterized using XRD, FTIR, TGA-DSC, and SEM-EDX methods. In general, the samples contain two main phases of calcium silicate, namely Ca2SiO4 (larnite) and Ca3SiO5 (alite). The mole percentage of calcium silicate increases with the increasing synthesis temperature and the calcined broiler chicken eggshell used as a precursor.
