Method for synergistically solidifying tailing sand through EICP-casein
The invention discloses a method for synergistically solidifying tailing sand through EICP-casein. The method comprises the following steps: 1) extracting urease, and measuring and adjusting the activity of the urease; 2) preparing a cementing liquid; (3) preparing a tailing sand-casein mixture; 4) mixing urease, a cementing solution and tailing sand-casein, and loading the mixture into a mold to prepare a sample; 5) maintaining the sample; 6) drying the sample; and 7) carrying out an unconfined compressive strength test on the sample. Compared with a pure EICP reinforcing method, the method has the advantages that the operation process is simple and convenient, and the strength of the sample is obviously improved. The method is scientific in principle and easy to implement, the reinforcing effect is good by combining the EICP with the casein to reinforce the tailing sand, and the peak compressive strength is high. The method does not cause significant increase in cost, and is suitable for popularization and implementation of industrial production.
本发明公开了一种EICP‑酪蛋白协同固化尾矿砂的方法,包括以下步骤:1)脲酶提取、测定并调节脲酶活性;2)胶结液制备;3)制备尾矿砂‑酪蛋白混合物;4)将脲酶、胶结液与尾矿砂‑酪蛋白混合,混合物装入模具制备试样;5)试样养护;6)试样干燥;7)对试样进行无侧限抗压强度试验。相较于单纯的EICP加固方法,本方法操作过程简便,且试样强度有明显的提高。本发明原理科学,易于实施,EICP联合酪蛋白加固尾矿砂具有良好的加固效果,峰值抗压强度高。该发明不会造成成本的显著提高,适合推广实施工业化生产。
