[0032] Example 1
[0033] A preparation process of modified fly ash includes the following preparation steps:
[0034] Step 1: Mix desulfurized gypsum and fly ash to obtain a mixture after being ground by a ball mill, wherein the weight ratio of desulfurized gypsum to fly ash is 1:5;
[0035] Step 2: subject the mixture to low-temperature plasma treatment;
[0036] Step 3: Add the modifier to the mixture after plasma treatment in step 2 and mix it evenly, add water to make a slurry, stir manually for 2 minutes, then add it to the cement slurry mixer for automatic stirring, and make 10cm×10cm after stirring ×40cm blanks are dried in an oven at 50℃ to obtain finished products.
[0037] The modifier includes 2 parts of montmorillonite, 1 part of graphite powder, 1 part of urotropine, 1 part of fly ash ceramsite and 0.5 part of polyaluminum iron sulfate.
