Abstract

Hydraulic hardened paste of magnesium-bearing phosphoaluminate-hydroxyapatite composite cement (MPAHC) reinforced by 0.5 wt.% addition of raw silk possesses splitting strength of 14.9 ± 0.2 MPa and Vickers micro-hardness of 2.22 GPa, which are increased by 22.2% and 42.3%, respectively, in comparison with that of the control ones after curing for 24 h at 37 °C. X-ray linear scanning analysis and FT-IR spectra suggest that the chemical bonds might have been developed at the interface between the treated raw silk and the hydrates in MPAHC hardened pastes.
