Titanium white waste acid is a kind of liquid waste that will seriously pollute the environment if handled improperly.Using titanium white waste acid to replace sulfuric acid when prepare magnesium oxysulfate cement can not only protect the environment but also save costs.The magnesium oxysulfate cement can be produced by reacting titanium white waste acid with magnesium oxide to form magnesium sulfate,and then adding light calcined magnesia and modifier citric acid.The setting time,compressive capacity,microstructure and phase composition of the magnesium oxysulfide cement were tested. Compared with the magnesium oxysulfate cement prepared by the traditional sulphuric acid method,the magnesium oxysulfate cement prepared by using the titanium white waste acid has a shorter setting time,and the compressive strength,microstructure and phase composition of the two methods were both consistent.It is feasible to prepare magnesium oxysulfide ce ment from titanium white waste acid.
