Sludge curing agent as well as preparation method and application thereof
The invention provides a sludge curing agent and a preparation method and application thereof, and belongs to the technical field of curing agents and solid waste resource utilization, the curing agent comprises the following raw materials by mass: 45%-65% of cement, 18%-30% of mineral powder, 9%-20% of fly ash and 8%-10% of curing agent master batch. Solid waste materials such as mineral powder and coal ash are used for achieving solidification and stabilization of the mud flat sludge, no special additive needs to be added, and the method has the advantages of being low in price and simple in material. Besides, the solid wastes such as the fly ash and the green mud recovered from the pulping alkali of the paper pulp mill are subjected to resource utilization, so that the economic benefit is increased, and meanwhile, the pollution problem of the ecological environment is relieved; meanwhile, sludge can be cured in situ, the curing speed is high, the construction period can be greatly shortened, the construction cost is reduced, and the method is suitable for large-scale sludge and soft foundation treatment; and the prepared sludge solidified soil meets the construction requirements of highway engineering, and has excellent compression resistance.
本发明提出了一种淤泥固化剂及其制备方法和应用，属于固化剂和固体废弃物资源化利用技术领域，该固化剂按照质量百分数计，原料包括：水泥45％～65％、矿粉18％～30％、粉煤灰9％～20％和固化剂母料8％～10％。即本发明利用矿粉、粉煤灰等固废材料实现滩涂淤泥固化及稳定化，且无需加入特殊添加剂，具有价格低廉，材料简单优点。此外，本发明对粉煤灰、纸浆厂制浆碱回收绿泥等固体废弃物进行资源化利用，增加经济收益的同时，减轻了生态环境的污染问题；同时本发明可原地固化淤泥，固化速度快，可以大大缩短施工工期，降低施工成本，适用于大规模的淤泥、软基础处理；且本发明制备得到的淤泥固化土满足公路工程施工要求，具有优异的抗压性能。
