磷石膏与生石灰混合材料化处理疏浚淤泥
isposal of dredging sludge by the mixture of phosphogypsum and quicklime
利用磷石膏与生石灰混合处理疏浚淤泥,与单用生石灰处理相比,处理效果明显更好,材料化土强度提高,处理周期减少。用磷石膏、生石灰混合处理疏浚淤泥时,其水化物不仅有水化硅酸钙将松散的土粒胶结成整体,而且还产生钙矾石,其晶体膨胀填充孔隙,使材料化土强度进一步提高。
he effect on developing a new geosynthetic material from dredging sludge by the mixture of phosphogypsum and quicklime may be better than that by mere quicklime because of improving of strength and shortening periods of disposing. When the method is adopted, in the hydrates of phosphogypsum and quicklime, not only calcium silicate hydrate cementing loose soil particles together, but ettringite is produced by the reaction of phosphogypsum with quicklime. It can expanse and fill up pores in the soil and then improve soil strength further.
