Embodiment 1
[0030] In this embodiment one, the method for preparing the calcium-magnesium-based composite material for dehydration and solidification of dredged silt is as follows:
[0031] Weigh each component according to the proportion: resin SAP 0.5wt.%, cement 6wt.%, dead burnt MgO 8wt.%, magnesium phosphate 13wt.%, metakaolin 8wt.%, active MgO 8wt.%, magnesium chloride 10wt.%. , 3wt.% of quicklime, 3wt.% of sodium silicate, 5.5wt.% of sodium hydroxide, 20wt.% of slag powder, 15wt.% of fly ash; composite material.
[0032] Performance Testing:
[0033]Add 250kg of dehydration-solidified calcium-magnesium-based composite material to each cubic meter of sludge, and set the initial moisture content of the sludge to 120%. After uniform mixing of the sludge and dehydrated-solidified calcium-magnesium-based composite material, prepare a sample with a diameter of 50mm and a height of 100mm , demolded after 3 days of standard curing, and continued curing to 7 days and 28 days, and three pa...
Embodiment 2
[0035] In this embodiment two, the method for preparing the calcium-magnesium-based composite material for dehydration and solidification of dredged silt is as follows:
[0036] Weigh each component according to the proportion: resin SAP 0.5wt.%, cement 6wt.%, dead-burned MgO 8wt.%, magnesium phosphate 13wt.%, metakaolin 8wt.%, active MgO 6wt.%, magnesium chloride 10wt.%. , quicklime 3wt.%, sodium silicate 6wt.%, sodium hydroxide 4.5wt.%, slag powder 20wt.%, fly ash 15wt.%; composite material.
[0037] Performance Testing:
[0038] Add 250kg of dehydration-solidified calcium-magnesium-based composite material to each cubic meter of sludge, and set the initial moisture content of the sludge to 120%. After the sludge and dehydrated-solidified calcium-magnesium-based composite material are evenly stirred, a sample with a diameter of 50 mm and a height of 100 mm is prepared. The mold was removed after 3 days of standard curing, and the curing was continued to 7 days and 28 days....
Embodiment 3
[0040] In this embodiment three, the method for preparing the calcium-magnesium-based composite material for dehydration and solidification of dredged silt is as follows:
[0041] Weigh each component according to the proportion: resin SAP 0.5wt.%, cement 6wt.%, dead-burned MgO 10.5wt.%, magnesium phosphate 15wt.%, metakaolin 8wt.%, active MgO 8wt.%, magnesium chloride 12wt. %, quicklime 2wt.%, sodium silicate 3wt.%, sodium hydroxide 3wt.%, slag powder 20wt.%, fly ash 12wt.%; then mix and mix evenly to get dredged silt dehydration solidified calcium magnesium base composite material.
[0042] Performance Testing:
[0043] Add 250kg of dehydration-solidified calcium-magnesium-based composite material to each cubic meter of sludge, and set the initial moisture content of the sludge to 120%. After the sludge and dehydrated-solidified calcium-magnesium-based composite material are evenly stirred, a sample with a diameter of 50 mm and a height of 100 mm is prepared. The mold was ...
