In this study, the phase development in the cement system α-TCP-OCP with phosphoric acid as a setting liquid was studied. The most promising formulation of α-TCP (60 wt%) and OCP (40 wt%) is proposed. This cement has the following characteristics: setting time 10 min, pH = 6.7, the compressive strength about 30 MPa, and high dissolution rate in an isotonic solution; the final wt% composition of α-TCP/DCPD/HA/OCP equals 27/38/20/15. Energy dispersive X-ray diffraction techniques were used for in situ monitoring of the processes taking place in the cement in real time.
在这项研究中，研究了以磷酸为凝固液的 α-TCP-OCP 水泥体系中的相发展。提出了最有前途的 α-TCP（60wt%）和 OCP（40wt%）配方。这种水泥具有以下特点：凝固时间 10 分钟，pH 值=6.7，抗压强度约 30MPa，在等渗溶液中具有较高的溶解速率；最终 wt%的 α-TCP/DCPD/HA/OCP 组成比例为 27/38/20/15。使用能量色散 X 射线衍射技术实时原位监测水泥中发生的过程。
