Embodiment 1
[0036] Embodiment 1: A preparation process of composite pile ready-mixed fluid solidified soil slurry, comprising the following steps:
[0037] Preparation of S1 modifier: Weigh 5.5Kg of carboxymethyl cellulose, add 5Kg of ethylene glycol monoallyl ether, 8Kg of polycarboxylate water reducer and 3.5Kg of polyether defoamer, and mix evenly to obtain modified sex agent.
[0038] S2 activator preparation: Weigh 7.5Kg triethanolamine, add 5Kg sodium sulfate, 7Kg calcium sulfoaluminate and 18Kg neutral nano-silica sol (sodium oxide content 0.15%, silicon dioxide content 40%, the rest is water, neutral nano-silica sol The median particle diameter (D50) of the silica sol is 44.3nm), and then 6Kg of 13X zeolite powder was added and mixed evenly to prepare the activator.
[0039]Preparation of S3 liquid solidified soil slurry: sieve the clay with a sieve with a hole diameter of 20 mm, and select clay with a particle size not greater than 20 mm. Screen the fine sand with a sieve with ...
Embodiment 2
[0041] The difference between Example 2 and Example 1 is that the neutral nano-silica sol is not added in Example 2, and the others are consistent with Example 1.
Embodiment 3
[0043] The difference between Example 3 and Example 1 is that Example 3 does not add 13X zeolite powder, and the others are consistent with Example 1.
