摘要
通过借鉴氯氧镁水泥领域的成果结论,用MgSO4代替MgCl2做成的硫氧镁水泥,以强度、耐水性为主要指标,研发性能优于氯氧镁的新型镁质胶凝材料,并探讨了改性后的镁质材料的性能,结果表明:硫氧镁水泥的耐水性能虽然优于氯氧镁水泥,但其强度不高;通过单一外加剂改性,并不能提高氯氧镁水泥及硫氧镁水泥净浆试块的耐水性能,但与玻璃纤维复合,可以制备耐水高强的镁质胶凝材料。
The magnesium oxysulfate cement was preparated by using MgSO4 instead of MgCI2. The new cementitious materials was researched and Its strength and water resistance were better than magnesium oxychloride cement, and discussed the performance of modified magnesia material. The results showed that：water resistance of magnesium oxysulfate cement was superior of, but its strength was not high; and water resistance of magnesium oxysulfate cement and magnesium oxychloride cement could not been improved through a single additive modification, but with glass fiber composite,water-resistant and high strength magnesia cementitious material could be prepared.
