Iron tailing sand doped wet-mixed mortar and preparation method thereof
The invention provides iron tailing sand doped wet-mixed mortar and a preparation method thereof. The wet-mixed mortar is prepared from 7.0%-15% of cement, 3.8%-5.2% of fly ash, 27%-32% of river sand, 40%-50% of iron tailing sand, 0.50%-0.60% of a mortar plastic stabilizer, 0.24%-0.38% of a mortar adjusting agent and 11%-13% of water and is prepared with the method as follows: the river sand, the iron tailing sand, the cement and the fly ash are mixed and stirred for 10-12s, and a dry mortar mixture is obtained; the mortar plastic stabilizer and the mortar adjusting agent are mixed with 60%-70% of water and then poured into the dry mortar mixture to be stirred for 15-20s, and a mixture is obtained; the remaining water is added to the mixture and stirred for 15-20s, and the uniform wet-mixed mortar is obtained. With the adoption of the preparation method, a wet-mixed mortar product with excellent quality and stable performance is provided for a construction project, and the problems that waste residues occupy land and pollute the environment and the like can be solved.
