With the increasing application of implants in the treatment of skeletal system defects, particularly bone cements, there is a growing demand for enhancing their mechanical properties, biocompatibility, and other critical characteristics. In this study, a calciumaluminum layered double hydroxide (LDH) was synthesized via the co-precipitation method and employed as an additive in calcium hydroxyapatite and polyvinyl alcoholbased bone cement. Bone cements were formulated with varying LDH concentrations ranging from 1% to 10%, and their properties were assessed using characterization techniques such as Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy-dispersive Xray spectroscopy (EDS), and elemental mapping. Nanoindentation studies and characterization analyses indicated that the optimal LDH concentration for improved performance was 7%.
