摘要
为了改善和提高硫氧镁水泥的基本性能,在硫氧镁水泥中掺入柠檬酸,文章研究了柠檬酸对硫氧镁水泥力学性能和耐久性能的影响规律。结果表明,柠檬酸可延缓硫氧镁水泥的凝结时间,提高硫氧镁水泥的强度,有效抑制硫氧镁水泥的收缩,提高镁水泥耐酸碱腐蚀能力,对硫氧镁水泥具有很好的改性作用。
In order to improve the basic performance of magnesium oxysulfate cement, the effects of citric acid on mechanical properties and durability of the magnesium oxysulfate cement are studied by mixing magnesium oxysulfate cement with citric acid. The results show that citric acid can delay the setting time of magnesium oxysulfate cement, improve the strength of magnesium oxysulfate cement, effectively inhibit the contraction of magnesium oxysulfate cement, and enhance acid and alkali resist- ance capacity of magnesium oxysulfate cement. Citric acid has good modification effects on magnesium oxysulfate cement.
