| titleOfInvention | Application of heavy metal sludge high temperature treatment slag and modified magnesium oxysulfate cement containing the slag |
| abstract | The invention discloses the application of high-temperature treatment slag of heavy metal sludge in modified magnesium oxysulfate cement. The ground powder obtained by high-temperature treatment of the slag obtained by mixing heavy metal sludge and construction slag is used as an active mineral admixture. The admixture is added to the modified magnesium oxysulfate 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, ground fine powder, water and modifier. The fine powder is used as the active mineral admixture in the preparation of the modified magnesium oxysulfate cement to replace 5-40 wt % of the light-burned magnesium oxide powder in an equivalent amount. The invention provides a new solution for the high-value resource utilization of heavy metal sludge, and the grinding of fine powder can obviously improve the fluidity of the pure slurry of the modified magnesium oxysulfate cement-based material and the convenience of on-site construction, and 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. |
