为解决固化疏浚泥无法储存的问题,提出了疏浚泥半固化处理方法,对不同水泥掺量和养护龄期的疏浚泥进行了击实试验,并利用击实土样进行了无侧限抗压强度试验。试验结果表明,当水泥掺量较大时,固化效果明显,但不易于击实;当水泥掺量适当时,击实效果明显,且击实强度随龄期的增加而增大,进而获得了最佳击实条件为水泥掺量为44g/kg时自然养护7d,其无侧限抗压强度可达188kPa。
In order to solve the problem that solidified dredged silt can not be stored, a dredging mud semi-solidification treatment method is proposed. Compaction tests of dredged mud with different cement content and curing age are carried out. Unconfined compressive strength Strength test. The test results show that when the cement content is large, the curing effect is obvious, but not easy to compaction; when the cement content is appropriate, the compaction effect is obvious, and the compaction strength increases with the increase of age, and then get The best compaction conditions for the cement content of 44g / kg natural conservation 7d, its unconfined compressive strength up to 188kPa.
