Embodiment 1
[0040] An artificial water storage stone, prepared from the following raw materials in parts by weight: 50g of recycled concrete fine aggregate, 41.5g of cement binder, 6.2g of water, 7g of polyphenylene particles, 0.3g of polycarboxylate superplasticizer, and Base cellulose 1.2g.
[0041] In this embodiment, the water storage stone is prepared by the following method:
[0042] (1) Add the recycled concrete fine aggregate, cement binder, water, polycarboxylate superplasticizer and methyl cellulose into the mixer according to the weight part, stir evenly, pour it into the disc granulator, and then put it into the disc granulator according to the weight part Add polystyrene particles for mixing and primary granulation;
[0043] (2) Feed the preliminarily made granules in step (1) into the double-roll granulator to granulate again, and then use the sieving machine to sieve, and recycle the products that do not meet the pore size requirements and return them to the double-roll gr...

[0046] An artificial water storage stone, prepared from the following raw materials in parts by weight: 60g of recycled brick fine aggregate, 35g of active powder concrete, 7.3g of water, 3g of polyphenylene particles, 0.5g of polycarboxylate superplasticizer, lignin sulfonate 0.3g of sodium nitrate, 0.4g of methyl cellulose, and 0.8g of polyvinyl alcohol.
[0047] In this embodiment, the water storage stone is prepared by the following method:
[0048] (1) Add regenerated brick fine aggregate, active powder concrete, water, polycarboxylate superplasticizer, sodium lignosulfonate, methyl cellulose, and polyvinyl alcohol into the mixer by weight and stir evenly, then pour into the disc In the granulator, polystyrene particles are added in parts by weight for mixing and preliminary granulation;
[0049] (2) Feed the preliminarily made granules in step (1) into the double-roll granulator to granulate again, and then use the sieving machine to sieve, and recycle the products that...
Embodiment 3
[0052] An artificial water storage stone, prepared from the following raw materials in parts by weight: 70g of recycled concrete fine aggregate, 26g of active powder concrete, 7.8g of water, 1g of polyphenylene particles, 0.8g of polycarboxylate superplasticizer, lignin sulfonate 0.7g of sodium phosphate, 0.2g of methylcellulose, and 1.3g of polyvinyl alcohol.
[0053] In this embodiment, the water storage stone is prepared by the following method:
[0054] (1) Add recycled concrete fine aggregate, active powder concrete, water, polycarboxylate superplasticizer, sodium lignosulfonate, methyl cellulose, and polyvinyl alcohol into the mixer by weight and stir evenly, then pour into the disc In the granulator, polystyrene particles are added in parts by weight for mixing and preliminary granulation;
[0055] (2) Feed the preliminarily made granules in step (1) into the double-roll granulator to granulate again, and then use the sieving machine to sieve, and recycle the products ...
