Lead-polluted soil curing agent combining red mud, carbide slag and ardealite and preparation method of lead-polluted soil curing agent
The invention discloses a lead-polluted soil curing agent combining red mud, carbide slag and ardealite and a preparation method of the of lead-polluted soil curing agent, belongs to the technical field of environmental geotechnical engineering, and can solve the problems that an existing cement curing agent cannot meet the requirement for repairing polluted soil easily and can affect the environment. Every 100 parts of lead polluted soil contains 5-10 parts of ordinary Portland cement, 2.5-5 parts of red mud, 1.25-5 parts of carbide slag and 1.25-5 parts of ardealite. Based on the curing mechanism of three industrial waste residues of red mud, carbide slag and ardealite, according to the chemical components and pH values of the three components, the three components are fully complemented and strengthened in performance from different effects of the three components, and the proportion of the three components is set accordingly, a novel curing agent which simultaneously meets the requirements of unconfined compressive strength, corrosivity, radioactivity, leaching toxicity, permeability and the like is developed, and the problems that an existing conventional cement curing agent is poor in repairing effect and the like are solved.
一种联合赤泥+电石渣+磷石膏的铅污染土固化剂及其制备方法,属于环境岩土工程技术领域,可解决现有水泥固化剂对污染土的修复难以满足要求,并且会对环境造成影响的问题。每100份铅污染土中含普通硅酸盐水泥5~10份、赤泥2.5~5份、电石渣1.25~5份、磷石膏1.25~5份。本发明基于“赤泥+电石渣+磷石膏”三种工业废渣的固化机理,根据三种组分化学成分及酸碱度,从各自发挥的不同作用,使三种组分在性能上充分实现互补和强化,据此设定三者相互之间的比例,研制出同时满足无侧限抗压强度、腐蚀性、放射性、浸出毒性、渗透性等要求的新型固化剂,解决了现有的常规水泥固化剂修复效果不佳等问题。
