Modified magnesium oxychloride cement dredged sludge curing agent and preparation method thereof
The invention discloses a modified magnesium oxychloride cement dredged sludge curing agent and a preparation method thereof, and belongs to the technical field of sludge curing treatment, and the method can be used for treating sludge produced in civil engineering and hydraulic engineering. The curing agent comprises the following components in parts by mass: 8-10 parts of magnesium oxychloride cement, 6-8 parts of sodium silicate, 4-5 parts of silica fume and 4-5 parts of fluidized bed combustion ash. The curing agent is mixed and stirred with sludge, the curing time is 28 d, and a large amount of hydration gelatinization products are formed through a series of hydration reactions and pozzolanic reactions, so that on one hand, industrial solid wastes such as silica fume and fluidized bed combustion ash are consumed, the curing treatment cost is reduced, and on the other hand, the strength and water resistance of a sludge cured body are improved; the water erosion resistance and the organic matter erosion resistance are better.
本发明公开一种改性氯氧镁水泥疏浚淤泥固化剂及其制备方法,属于淤泥固化处理技术领域,该方法可以处理土木工程、水利工程中产的淤泥。固化剂按照质量份数计,包括如下组分:氯氧镁水泥8~10份、硅酸钠6~8份、硅灰4~5份、固硫灰4~5份。本发明通过与淤泥进行混合搅拌,固化时间为28d,经过一系列水化反应和火山灰反应形成大量的水化胶凝产物,一方面消耗了硅灰和固硫灰这类工业固体废料降低了固化处理的成本,另一方面改善了淤泥固化体的强度和耐水性,使其抵抗水的侵蚀和耐有机质侵蚀的能力更好。
