Embodiment 1
[0040] A polyaluminum chloride waste slag dry-mixed mortar, calculated in parts by mass, comprising the following raw materials: 8 parts of thermally activated polyaluminum chloride waste slag (calcined at a high temperature of 800° C. for 2 hours), 23 parts of PO42.5 ordinary Portland cement, medium sand 55 parts, 4 parts fly ash, 15 parts water, 0.05 part defoamer, 0.22 part water reducing agent.
[0041] The preparation method of polyaluminum chloride waste residue dry-mixed mortar is as follows: heat-activated polyaluminum chloride waste residue, PO42.5 ordinary Portland cement, fly ash, medium sand and defoamer are sequentially added to a mortar mixer, and stirred evenly ( 1-3min) to obtain a premix; then add the water reducing agent and water to the mortar mixer in turn, and stir evenly (1-5min) to obtain polyaluminum chloride waste slag dry-mixed mortar S-1.
Embodiment 2
[0043] A polyaluminum chloride waste slag dry-mixed mortar, calculated in parts by mass, comprising the following raw materials: 8 parts of thermally activated polyaluminum chloride waste slag (calcined at a high temperature of 800° C. for 2 hours), 23 parts of PO42.5 ordinary Portland cement, medium sand 55 parts, 4 parts fly ash, 15 parts water, 5 parts styrene-acrylic emulsion, 0.05 part defoamer, 0.20 part water reducing agent.
[0044] The preparation method of polyaluminum chloride waste residue dry-mixed mortar is as follows: adding heat-activated polyaluminum chloride waste residue, PO42.5 ordinary Portland cement, medium sand, fly ash and defoamer into a mortar mixer in turn, and stirring them evenly ( 1-3min) to obtain a premix; then add the styrene-acrylic emulsion, water reducing agent and water to the mortar mixer in turn, and stir evenly (1-5min) to obtain polyaluminum chloride waste residue dry-mixed mortar S-2.
Embodiment 3
