AB - The curing agent used to enhance and harden dredged sludge from urban rivers  was formulated from industrial waste materials, including carbide slag,  blast furnace slag, fly ash, and cement. Laboratory tests were conducted to  examine the compressive strengths of the sludge samples after 7, 14, and 28  days of curing. Additionally, X-ray diffraction and thermogravimetric  analysis were employed to examine the formation and microstructure  distribution characteristics of the solidified sludge products. These  methods also provided insights into the synergistic curing mechanism of the  cement-carbide slag-slag-fly ash composite system. The findings demonstrated  that the following ratio of curing agent to cement: carbide slag: slag: fly  ash = 10 : 5 : 7 : 3 is the ideal one.
