| Abstract | In this work early mechanical properties of α-TCP cement with different initial liquid phase pH values are investigated. Early compressive strength (at 24 h) is higher if initial pH of the liquid phase is acidic – 7 MPa (at pH 6) compared to basic initial pH – 4 MPa (at pH 8). This can be attributed to more rapid conversion of α-TCP to calcium deficient hydroxyapatite and more intense mechanical interlocking of precipitated crystals at high initial pH values. |
