D-异抗坏血酸钠对硫氧镁水泥性能的影响
Effect of D-Sodium Erythorbate on Properties of Magnesium Oxysulfate Cement
摘要
Abstract
The effect of D-sodium erythorbate on the setting time,conductivity,compressive strength,and water resistance of magnesium oxysulfate cement was investigated.The phase composition and microstructure of hydration products of magnesium oxysulfate cement were analyzed using X-ray diffraction,synchronous thermal analysis,and scanning electron microscopy.The results show that the addition of chemical additive D-sodium erythorbate significantly prolongs the setting time of magnesium oxy sulfate cement.Additionally,the formation of a substantial amount of 5Mg(OH)2·MgSO4·7H2O(5·1·7)crystalline phase greatly improves the compressive strength and water resistance of magnesium oxysulfate cement.关键词
