Abstract
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 resistance capacity of magnesium oxysulfate cement.Citric acid has good modification effects on magnesium oxysulfate cement.
