Fluid soil based on dredged sludge and preparation method thereof
The invention discloses fluid soil based on dredged sludge and a preparation method thereof. The fluid soil comprises the following raw materials: cement, quick lime, fly ash, dredged sludge and super absorbent resin. Wherein the cement accounts for 6%-10% of the mass of the dredged sludge, the fly ash accounts for 12%-20% of the mass of the dredged sludge, the quick lime accounts for 5%-10% of the mass of the dredged sludge, and the super absorbent resin accounts for 0.1%-2.5% of the mass of the dredged sludge; the water content of the dredged sludge is 2-3 times of the liquid limit water content; the preparation method comprises the following steps: (1) uniformly mixing the cement, the quick lime and the fly ash; (2) uniformly mixing the dredged sludge and the super absorbent resin; (3) adding the mixture obtained in the step (1) into the mixture obtained in the step (2), and uniformly stirring; according to the fluid soil, cement, quicklime, fly ash and super absorbent resin are directly doped into dredged sludge, and the dredged sludge is converted into fluid soil which is good in fluidity and good in strength after being cured and is used for foundation pit and roadbed filling.
本发明公开了一种基于疏浚淤泥的流态土及其制备方法，其原料包括水泥、生石灰、粉煤灰、疏浚淤泥和高吸水树脂；其中水泥占疏浚淤泥质量的6％～10％，粉煤灰占疏浚淤泥质量的12％～20％，生石灰占疏浚淤泥质量的5％～10％，高吸水树脂占疏浚淤泥质量的1‰～2.5‰；所述疏浚淤泥的含水率为2～3倍液限含水率；其制备方法包括以下步骤：(1)将水泥、生石灰和粉煤灰混合均匀；(2)将疏浚淤泥和高吸水树脂混合均匀；(3)将步骤(1)混合料加入步骤(2)的混合料中搅拌均匀；该流态土在疏浚淤泥中直接掺入水泥、生石灰、粉煤灰以及高吸水树脂，将其转化成流动性好、固化后强度好的流态土用于基坑及路基填方用土。
