Embodiment 1
[0017] The realization process of the alkali-activated carbonate-slag grouting material pretreatment package retarding method is:
[0018] (1) At normal temperature, mix the water-quenched blast furnace slag powder with the alkali component solution whose modulus is 2.0, and the sum of the concentration of sodium oxide and silicon oxide mass percentage is 12%, and stir until uniform, and the water-quenched blast furnace slag powder and alkali The mass ratio of the component solutions is 1:0.75. After the slurry is sealed and stored for 24 hours, the pretreated slag slurry is prepared.
[0019] (2) In terms of parts by mass, 10 parts of pretreated slag slurry and 26 parts of modulus are 2.0, and the sum of sodium oxide and silicon oxide mass percentage concentrations is 39% of the alkali component solution and 32 parts of marginal carbonic acid The salt ore powder is stirred until uniform, and the alkali-activated carbonate-slag grouting material is prepared.
