N2 - To investigate the degradability and biomineralization ability of Portland cement (PC), samples of PC were immersed in simulated body fluid (SBF) for 3, 7 and 14 d respectively. X-ray diffraction (XRD), a Fourier transform infrared spectrophotometer (FTIR) and a scanning electron microscope (SEM) were used to investigate the biomineralization ability of PC; meanwhile, the weight loss of the samples and the pH value changes of their immersion media were monitored. The results show that with the soaking time prolonged, the weight of PC increases. The immersion media has a high alkalinity in the first three days, and then, the pH value declines. The XRD and FTIR patterns and the SEM images show that in SBF for 3 days, calcium carbonate is formed on the surface of PC and for 7 days carbonated hydroxyapatite is formed. Therefore, PC displays good biomineralization ability in SBF.
