抄録	The use of biocement represents a sustainable and innovative approach in geotechnical engineering. However, achieving optimal results often necessitates additional treatment cycles according to the current strength models based on sediment content. This study investigates the utilization of kitchen waste bones as a sustainable source of calcium and phosphorus to enhance biocement strength through controlled phase transformations. The objective is to induce the phase transformation of sediment from brushite to hydroxyapatite by increasing temperature and pH. This transformation was verified through X-ray diffraction (XRD) and energy-dispersive spectroscopy (EDS) analyses, confirming the successful conversion of calcium phosphate phases. Compared to samples with similar sediment content, the unconfined compressive strength (UCS) of the samples subjected to phase transformation increased by more than fivefold, indicating a substantial improvement in strength within the same treatment cycles. Overall, these findings emphasize the potential of kitchen waste bones in advancing sustainable biocement practices, providing a crystal transformation solution that significantly enhances the performance of biocement.
