Embodiment 1
[0014] The two-liquid quick-setting slurry is composed of the following components: Liquid A: Portland cement 50%, water 49.475%, inorganic sodium salt 0.5%, organic alcohol early strength agent 0.025%; liquid B: fly ash 43.6%, Sodium silicate 20.05%, water 36.35%. The volume ratio of liquid A and liquid B is 1:1.
[0015] The calculus rate of the slurry in this embodiment is 100%, and the gel time is 36s, which has obvious characteristics of fast setting and high calculus rate.
[0016] In order to characterize the early strength performance of the grout, the hourly compressive strength and later strength of the grout stone body were measured. The experimental results are shown in Table 1.

[0018]
[0019] It can be seen from Table 1 that the slurry has strength within 1 hour, the compressive strength of the stone body can reach 1.5MPa at 6 hours, and the compressive strength can reach 9MPa at 28 days.
Embodiment 2
[0021] The two-liquid quick-setting slurry is composed of the following components: A liquid A: Portland cement 50%, water 49.45%, inorganic sodium salt 0.5%, organic alcohol early strength agent 0.05%; B liquid B: fly ash 46.2% %, sodium silicate 16.94%, water: 36.86%. The volume ratio of liquid A and liquid B is 1:1.
[0022] The calculus rate of the slurry in this embodiment is 100%, and the gel time is 82s, which has obvious characteristics of fast setting and high calculus rate.
[0023] In order to further characterize the early strength performance of the slurry, the hourly compressive strength and later strength of the slurry stone body were measured. The experimental results are shown in Table 2.

Embodiment 3
[0027] The two-liquid quick-setting slurry is composed of the following components: A liquid A: Portland cement 50%, water 49.2%, inorganic sodium salt 0.75%, organic alcohol early strength agent 0.05%; B liquid B: fly ash 48.8% %, sodium silicate 13.9%, water 37.3%. The volume ratio of liquid A and liquid B is 1:1.
[0028] The calculus rate of the slurry in this embodiment is 100%, and the gel time is 124s, which has obvious characteristics of fast setting and high calculus rate.
[0029] In order to further characterize the early strength performance of the slurry, the hourly compressive strength of the slurry stone body was measured. The experimental results are shown in Table 3.
