| titleOfInvention | Application of heavy metal sludge high temperature treatment slag and modified magnesium oxysulfide cement containing the slag |
| abstract | The invention discloses the application of heavy metal sludge high-temperature treatment slag in modified magnesium oxysulfide cement. The ground powder obtained by mixing heavy metal sludge with construction dregs and grinding the slag obtained by high-temperature treatment is used as an active mineral mixed with The mixture is added to the modified magnesium oxysulfide cement. At the same time, a modified magnesium oxysulfide cement containing heavy metal sludge high-temperature treatment slag is disclosed. The modified magnesium oxysulfide cement is composed of light-burned magnesium oxide powder, magnesium sulfate heptahydrate, finely ground powder, water and a modifier. The fine powder is used as an active mineral admixture in the preparation of the modified magnesium oxysulfide cement to replace 5-40 wt% of the light-burned magnesium oxide powder in equal amounts. The invention provides a new solution for the high-value resource utilization of heavy metal sludge. The finely ground powder can significantly improve the fluidity of the modified magnesium oxysulfide cement-based material and the convenience of on-site construction. Guarantee the mechanical properties of modified magnesium oxysulfate cement. The modified magnesium oxysulfate cement of the invention has a consolidation effect on heavy metals such as Ni, Cr, Zn and Cu. |
