dc.description.abstract | This research aimed to study the optimum conditions for making raw lime from shells, which consisted of 9 conditions: calcined at three levels of 700, 800, and 900 degrees Celsius for 1, 2, and 3 hours. Calcium element content in raw lime using X-ray fluorescence (XRF) measurement, and structural analysis of calcium compounds by X-Ray Diffraction (XRD). The research results were found.
1. Optimal conditions for making lime mortar are temperature 800 degrees Celsius, duration 2 hours. The physical characteristics of raw lime are white and porous.
2. The calcium content from the shells' calcination at 800 degrees Celsius for 1, 2, and 3 hours was 98.22%, 96.70%, 97.89%.
3. Changes in the calcium compounds of raw lime obtained by calcining the shell at 800 degrees Celsius for 1 hour were mainly found in the form of calcium carbonate (CaCO3). At 2, 3 hours, calcium carbonate (CaCO3) is mostly converted to form calcium hydroxide (Ca(OH)2)compound, calcium oxide (CaO) compound is formed. | en_US |
