a.测定疏浚淤泥的含水量、粘土成分和有机质含量, A. determination of water content, clay composition and organic matter content of dredged silt. b.配制固化剂:固化剂的主要成分包括起固化作用的水泥和生石灰,水泥与石灰的重量比例在1:1-4:1之间;废石膏用作减水剂,为水泥和石灰质量之和的1~8%;粉砂或粉煤灰作为骨料,用量为水泥和石灰质量之和的3~5%; B. preparation curing agent: the main components of the curing agent are cement and lime, the weight ratio of cement to lime is between 1:1-4:1; waste gypsum
淤泥固化技术在一些沿海地区等到了应用。其利用机械搅拌将淤泥和固化剂按照适当比例混合,拌制并经硬化,形成适用于工程的材料——淤泥固化土。 Sludge solidification technology has been applied in some coastal areas. The sludge and curing agent are mixed in an appropriate proportion by mechanical mixing, mixed and hardened to form a material suitable for the project - sludge solidified soil. 作为一种新型、实用、环保的地基材料,淤泥固化土可用于道路、堆场、桩基垫层以及其它土体工程的地基建设。不同
