Examples
Example Embodiment
[0010] Example one:
[0011] The composition and ratio are 66.5% slag powder, 10% Portland cement, 6% aluminate cement, 10% fly ash, 5% gypsum, 2% sodium metasilicate and 0.5% 4mm length polypropylene The fibers are evenly mixed to prepare a slag base base excitation material. When the concentration of the tailings (the tailings are finer) is 60%, the material with different ash-sand ratios (1:6, 1:12) and the tailings are mixed uniformly. Test the physical properties of the material. The following table shows the comparison between the slurry prepared with this material and the slurry prepared with cement.

Example Embodiment
[0013] Embodiment two:
[0014] The composition and ratio of 64% slag powder, 10% Portland cement, 5% silica fume, 5% gypsum, 10% quicklime, and 6% expansion agent are mixed uniformly to prepare a slag base alkali excitation material. When the tailings concentration is 70%, mix the material with different ash-sand ratios (1:10, 1:15) with the tailings evenly. Test the physical properties of the material. The following table shows the comparison between the slurry prepared with this material and the slurry prepared with cement.
