Embodiment 1
[0032] A shell coating method for unburned ceramsite in dredged bottom mud, comprising the following steps:
[0033] 1. Pretreatment of raw materials: crush cement, quicklime, glass fiber powder and fly ash to 100 mesh and moisture content of 10% with a pulverizer;
[0034] 2. Ingredients: The dry mixed shell material is composed of cement, quicklime, glass fiber powder and fly ash; unfired ceramsite is weighed; the ratio of the dry mixed shell material to the dredged bottom mud unfired ceramsite is: The mass percentage of raw materials is 16% of cement, 3% of quicklime, 5% of glass fiber powder, 4% of fly ash, and 70% of unfired ceramsite in dredged bottom mud; the mixed solution is composed of white latex and water, of which 2% white latex , the mass ratio of white latex to water is 1:4;
[0035] Wherein, each above-mentioned mass percentage is the mass percentage that each raw material accounts for the total mass of dry mixed shell material, dredged bottom mud unburned cer...

[0041] A shell coating method for unburned ceramsite in dredged bottom mud, comprising the following steps:
[0042] 1. Pretreatment of raw materials: pulverize cement, quicklime, glass fiber powder and fly ash to 150 mesh and moisture content of 8% with a pulverizer;
[0043] 2. Ingredients: The dry mixed shell material is composed of cement, quicklime, glass fiber powder and fly ash; unfired ceramsite is weighed; the ratio of the dry mixed shell material to the dredged bottom mud unfired ceramsite is: The mass percentage of raw materials is 16% of cement, 4% of quicklime, 4% of glass fiber powder, 3% of fly ash, and 70% of unburned ceramsite for dredging bottom mud; the mixed solution is composed of white latex and water, of which white latex is 3% , the mass ratio of white latex to water is 1:8;
[0044] Wherein, each above-mentioned mass percentage is the mass percentage that each raw material accounts for the total mass of dry mixed shell material, dredged bottom mud unb...
Embodiment 3
[0050] A shell coating method for unburned ceramsite in dredged bottom mud, comprising the following steps:
[0051] 1. Pretreatment of raw materials: pulverize cement, quicklime, glass fiber powder and fly ash to 200 mesh and moisture content of 7% with a pulverizer;
[0052] 2. Ingredients: The dry mixed shell material is composed of cement, quicklime, glass fiber powder and fly ash; unfired ceramsite is weighed; the ratio of the dry mixed shell material to the dredged bottom mud unfired ceramsite is: The mass percentage of raw materials is 12% of cement, 4% of quicklime, 6% of glass fiber powder, 3% of fly ash, and 70% of unburned ceramsite for dredging bottom mud; the mixed solution is composed of white latex and water, of which 5% is white latex , the mass ratio of white latex to water is 1:1;
[0053] Wherein, each above-mentioned mass percentage is the mass percentage that each raw material accounts for the total mass of dry mixed shell material, dredged bottom mud unb...
