Preparation method of sludge-based artificial building aggregate
The invention provides a preparation method of sludge-based artificial building aggregate, which comprises the steps of providing sludge, and pretreating the sludge to obtain dry sludge powder; mixingthe dried sludge powder with an inorganic binder, a mineral admixture and an excitant according to a part ratio of (50-90): (5-20): (1-30): (0.5-5) to obtain a first mixture; and mixing and granulating the first mixture and water to obtain the artificial building aggregate. According to the method, the sludge serves as a main component, the inorganic adhesive is used for crosslinking and curing harmful components, it is guaranteed that the artificial building aggregate has enough mechanical strength and excellent properties, the sludge can be recycled on a large scale through the method, andon the other hand, the artificial building aggregate can replace natural aggregate to be exploited and is widely applied to engineering such as buildings.
本申请提供了一种基于淤泥的人造建筑骨料的制备方法,包括如下步骤:提供淤泥,将淤泥进行预处理得到干燥淤泥粉末;将所述干燥淤泥粉末与无机粘合剂、矿物掺合料和激发剂进行混料处理,得到第一混合物,其中,所述干燥淤泥粉末、所述无机粘合剂、所述矿物掺合料和所述激发剂的份数比为(50~90):(5~20):(1~30):(0.5~5);将所述第一混合物和水进行混合造粒处理,得到所述人造建筑骨料。该方法以淤泥为主要组分,以无机粘合剂进行交联并固化有害成分,保证人造建筑骨料具有足够的力学强度,性质优异,该方法能够对淤泥进行大规模的回收利用,另一方面,人造建筑骨料可代替天然骨料的开采,广泛应用于建筑等工程。
