摘要
本文探讨了硫氧镁水泥(MOS)的微观结构和力学性能。结果发现硫氧镁水泥具有较高的力学性能,这得益于硫氧镁水泥的孔径主要分布在纳米量级上,几乎没有有害大孔,以及棒状的水化产物堆积交叉。MOS水泥主要由未完全反应氧化镁和水化产物5 Mg(OH)_(2)·MgSO_(4)·7H_(2)O(5·1·7相)组成,5·1·7相微观形貌为微米级的棒状结构。
The microstructure and mechanical properties of magnesium oxysulfate cement(MOS)was studied in this work.The excellent mechanical properties of MOS cement are mainly related to the nanometer-scale pore sizes,and the stacked and intersected rod-shaped hydration products.The MOS cement is mainly composed of incompletely reacted magnesium oxide and hydration product 5 Mg(OH)_(2)•MgSO_(4)•7H_(2)O(5•1·7 phase)with micron rod structure.
