Examples
Embodiment 1
[0026] A kind of ready-mixed mortar prepared by using a large amount of furnace bottom slag. The mass parts of the ready-mixed mortar include: 100 parts of cement, 10 parts of thickened powder, 60 parts of fly ash, 648 parts of sand, 111 parts of furnace bottom slag, 0.111 parts of water reducing agent.
[0027] Among them, polycarboxylic acid is selected as the water reducing agent.
[0028] Among them, the particle size of the furnace bottom slag is less than 0.63mm.
[0029] Wherein, the bottom slag is pretreated bottom slag, and the pretreated bottom slag is obtained by soaking a surfactant and a coupling agent.
[0030] Wherein, the surfactant is selected from the fatty alcohol sulfate anion.

The mass parts of the ready-mixed mortar include: 105 parts of cement, 15 parts of thickened powder, 70 parts of fly ash, 486 parts of sand, 222 parts of furnace bottom slag, 0.222 parts of water reducing agent.
[0033] Among them, polycarboxylic acid is selected as the water reducing agent.
[0034] Among them, the particle size of the furnace bottom slag is less than 0.63mm.
[0035] Wherein, the bottom slag is pretreated bottom slag, and the pretreated bottom slag is obtained by soaking a surfactant and a coupling agent.
[0036] Wherein, the surfactant is selected from the fatty alcohol sulfate anion.
Embodiment 3
[0038] A kind of ready-mixed mortar prepared by using a large amount of furnace bottom slag.
