| Abstract: |
| Boron mud is industrial waste residue produced in the production process of borax and boric acid. A large amount of discharge not only occupies a large amount of land, causes groundwater pollution, and scatters into dust after water loss, and also causes air pollution. Boron mud was doped into magnesium phosphate cement prepared from dead-burned magnesia and potassium dihydrogen phosphate, and the effect of boron mud as admixture on the properties of magnesium phosphate cement was studied. The research results show that boron mud can prolong the retardation time of magnesium phosphate cement and improve the compressive strength of cement. The experimental results show that when the content of boron mud is 10%, the setting time of cement is extended from 29 min to 35 min, and the compressive strength of cement increases from 56.21 MPa to 58.7 MPa. XRD analysis results show that the addition of boron mud does not change the mineral phase structure of magnesium phosphate cement. This study can provide a basis for the resource utilization of boron mud solid waste. |
