Solidified dredged sludge block based on alkali-activated cementing material and preparation method of solidified dredged sludge block
The invention discloses a solidified dredged sludge block based on an alkali-activated cementing material. The solidified dredged sludge block comprises the following raw materials in parts by mass: 16-20 parts of an alkali-activated cementing material, 65-70 parts of dredged sludge, 15 parts of water and 1-2 parts of polypropylene fibers. The invention also discloses a preparation method of the solidified dredged sludge block based on the alkali-activated cementing material, which comprises the following steps: S01, adding the alkali-activated cementing material and the polypropylene fiber into a stirrer, carrying out dry mixing, adding water, and uniformly conducting stirring and mixing; S02, adding dredged sludge, and conducting stirring in a stirrer to obtain a uniformly mixed material; S03, adopting a microcomputer to control an electro-hydraulic servo universal testing machine to perform one-time loading forming; and S04, putting the formed material in a room, and naturally and regularly sprinkling water for maintenance. The invention provides the solidified dredged sludge block based on the alkali-activated cementing material and the preparation method of the block, and the block can prevent industrial solid waste and dredged sludge from polluting the environment, improve the utilization rate of dredged sludge generated in channel improvement engineering, and improve the utilization rate of solid waste fly ash and the like.
本发明公开了一种基于碱激发胶凝材料的固化疏浚淤泥块体，原料的组成成分及质量份数分别为：碱激发胶凝材料16～20份，疏浚淤泥65～70份，水15份，聚丙烯纤维1～2份。本发明还公开一种基于碱激发胶凝材料固化疏浚淤泥块体的制备方法，包括以下步骤：S01、向搅拌机加入碱激发胶凝材料和聚丙烯纤维，干拌，再将水加入搅拌均匀混合；S02、加入疏浚淤泥，在搅拌机中搅拌得到混合均匀物料；S03、采用微机控制电液伺服万能试验机一次加载成型；S04、放于室内自然定期洒水养护。本发明提供一种基于碱激发胶凝材料固化疏浚淤泥的块体及其制备方法，能够避免工业固体废弃物和疏浚淤泥对环境造成污染，提高航道整治工程中产生疏浚淤泥的利用率，提高固体废弃物粉煤灰等的利用率。
