This study aimed to investigate chemical compositions and physical properties of local-made laboratory-synthesized fast setting tricalcium silicate cement for dental application. The laboratory-synthesized tricalcium silicate (TCS) powder was prepared by sintering silica (SiO₂) and calcium carbonate (CaCO₃) at 1450°C for 2 hours. The chemical composition of the TCS powder was analyzed by X-ray diffraction analysis (XRD). To develop fast setting TCS cement, zircon (ZrSiO₄) at the amount of 10%, 20%, and 30% was added to TCS as a radiopacifier. Calcium chloride (CaCl₂) at the concentration of 20% was used as an accelerator. Physical properties of the prepared materials were investigated accordingly to ISO 6876:2012 and 9917-1:2007 including initial and final setting time, compressive strength, radiopacity, and pH. XRD showed that tricalcium silicate was the main component of the TCS powder and Biodentine. TCS cement with a higher concentration of zircon exhibited a higher setting time. At the concentration of 20% zircon, the setting time of TCS cement was not significantly different from Biodentine. Adding zircon at a concentration of more than 10% resulted in higher compressive strength similar to Biodentine. Varying the amount of zircon to TCS did not affect pH values. At the duration of 3 hours to 3 weeks, TCS cement showed higher pH values in comparison to Biodentine (in the range of 12.1 to 12.8). TCS with 20% and 30% zircon showed higher radiopacity than Biodentine (5.64 and 6.47 mm of aluminum). In comparison to Biodentine, the local-made laboratory-synthesized TCS cement with 20% zircon showed suitable physical properties for dental application.
