摘要
本文用 XRD 及 EPMA 法观察,研究不同环境条件下的抗水氯氧镁水泥硬化体的反应产物和结构特征,结果表明:反应产物5Mg(OH)_2·MgCl_2.8H_2O 即5·1·8的稳定性与否直接关系到氯氧镁水泥抗水性能的好坏:它与未反应 MgO 的稳定存在是其以凝胶相胶结结晶相这一显微结构的必然结果.
The reaction products and structural features of hardened water-resisting magnesium oxychoride cements under different environmental conditions were observed and studied by XRD and EPMA methods.The results have shown that the stableness of the reaction product 5Mg(OH)_2·MgCl_2·8H_2O has a direct bearing on the water resistance of magnesium oxychloride cements.Its stable co—existance with unreacted MgO is a certain result from the microstructure in Which the crystalline phase is bonded with a gel phase.
