Soil stabilizer
The invention discloses a soil stabilizer, which is prepared from the following components in parts by weight: 8-10 parts of cement, 8-12 parts of red mud, 2-3 parts of sodium sulfate and 1-2 parts ofcalcium acetate, wherein the red mud is subjected to a drying treatment at 70-80 DEG C, and the cement is PO42.5 cement. The invention also discloses a preparation method of the soil stabilizer. Thepreparation method comprises the following steps: firstly, drying red mud at 70-80 DEG C; weighing the components according to a weight ratio, then mixing and stirring the components to obtain a mixture; and carrying out a ball-milling treatment on the mixture to obtain the product, wherein the stirring time ranges from 20 to 30 minutes, and the ball milling time ranges from 90 to 120 minutes. Byoptimizing the dosage of each component, the soil stabilizer with high early strength and high heavy metal removal rate can be obtained.
本发明公开了一种土壤固化剂，由以下组分及重量份组成：水泥8‑10份，赤泥8‑12份，硫酸钠2‑3份，醋酸钙1‑2份。所述的赤泥是经过70‑80℃烘干处理。所述水泥为PO42.5水泥。本发明还公开了该土壤固化剂的制备方法，包括以下步骤：首先将赤泥经70‑80℃烘干处理；按照重量配比称取各组分，然后将各组分混合并搅拌，得到混合料；再将混合料球磨处理后即得。其中，搅拌时间为20‑30min，球磨时间为90‑120min。本发明通过优化各组分用量，能够获得早期强度高、重金属去除率高的土壤固化剂。
