摘　　要：本研究探讨了葡萄糖酸亚铁对氯氧镁水泥(MOC)性能的改善,包括抗压强度、耐水性和降解性等性能。实验中,葡萄糖酸亚铁按照0.2%~0.8%(质量分数)的不同比例加到MOC中。研究显示:0.2%的葡萄糖酸亚铁可将MOC的7 d抗压强度提高至(78.14±1.32)MPa,比空白组高出19.3%;改性MOC在耐水性测试中显示出较高的7 d软化系数(0.59),优于未改性样本(0.29);在0.8%的葡萄糖酸亚铁掺量下,MOC浆体的屈服应力和塑性黏度分别降低了9.118 Pa和0.112 Pa·s,改性MOC的流动性较好,方便实际应用操作调控。这些结果证明了葡萄糖酸亚铁在改善MOC抗压强度、耐水性和调节降解性方面有着出色的潜力。This study explored the enhancement of magnesium oxychloride cement(MOC)properties by ferrous gluconate,including compressive strength,water resistance and degradability.In experiments,ferrous gluconate was added to MOC at varying proportion from 0.2%to 0.8%(mass fraction).The results show that 0.2%ferrous gluconate increases the 14 d compressive strength of MOC to(78.14±1.32)MPa,which is 19.3%higher than that of the control group.Additionally,the modified MOC demonstrates a higher 7 d softening coefficient(0.59)in water resistance tests,superior to that of the unmodified sample(0.29).At the dosage of 0.8%ferrous gluconate,the yield stress and plastic viscosity of MOC paste are reduced by 9.118 Pa and 0.112 Pa·s,respectively.The modified MOC has better fluidity and is convenient for practical application operation and control.These results confirm the significant potential of ferrous gluconate in enhancing the compressive strength,water resistance,and regulating the degradability of MOC.
