摘要：新型无机骨粘结剂磷酸镁水泥 ( MPC)的主要反应物——重烧 Mg O的活性与 MPC的性能密切相关。本文用比表面积法、碘吸附法、物相分析法、动力学分析法对不同 Mg O的活性进行了表征 ,并考察了重烧 Mg O的活性对 MPC材料凝结时间、30 min抗压强度以及水化温升的影响。结果表明 ,比表面积法、碘吸附法、物相分析法不能用于重烧 Mg O粉活性的测定 ,而动力学分析法用于表征重烧 Mg
The activity of dead burned magnesia is closely related to the properties of the new bio material magnesium phosphate cement (MPC). In this paper, the activity with respect to different species of magnesia has been quantified by the different methods of specific surface area, iodine number, content of activation MgO and the rate of reaction with citric acid. The relationship among the activity of dead burned magnesia, the setting time, compressive strength and the maximum temperature of MPC has also been studied. The results show that the methods of specific surface area, iodine number and the content of activation MgO can not be used to quantify the activity of dead burned magnesia, but the rate of reaction with citric acid is available for measuring the dead burned MgO activity.
