Embodiment 1
[0021] Embodiment one: take by mass parts:
[0022]
[0023] Its concrete preparation steps are as follows:
[0024] ①Put the redispersible latex powder into the mixer, gradually add lithium slag, stir evenly, add active powder and stir evenly;
[0025] ② Add water reducer and defoamer to water and stir to obtain a mixed solution, add 80% of the mixed solution to the dry powder stirred in the first step and stir for 10-25 minutes, add the remaining mixed solution, and stir for 3-5 minutes;
[0026] ③Slowly add fiber and stir evenly;
[0027] ④ Mix the stirred slurry with cement and sand in pouring or jetting molds, and demould after 24 hours to obtain ultra-high toughness self-curing cement-based products.
Embodiment 2
[0028] Embodiment two: take by mass parts:
[0029]
[0030]
[0031] Its concrete preparation steps are as follows:
[0032] ①Put the redispersible latex powder into the mixer, gradually add lithium slag, stir evenly, add active powder and stir evenly;
[0033] ② Add water reducer and defoamer to water and stir to obtain a mixed solution, add 80% of the mixed solution to the dry powder stirred in the first step and stir for 10-25 minutes, add the remaining mixed solution, and stir for 3-5 minutes;
[0034] ③Slowly add fiber and stir evenly;
[0035] ④ Mix the stirred slurry with cement and sand in pouring or jetting molds, and demould after 24 hours to obtain ultra-high toughness self-curing cement-based products.
[0036] The invention uses dispersible latex powder to pretreat lithium slag, utilizes the hydrophobicity of organic groups to reduce the water absorption of lithium slag during concrete mixing, and then the dispersible latex powder is redispersed when it m...
