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
淤泥固化土可用于多类工程建设,能够替代抛石挤淤填筑的传统工艺,解决沿海石料不足及破坏山体的问题,减少了大量石料的运输,用资源循环利用的方式达到了节能减排的效果。 Sludge solidified soil can be used in many kinds of engineering construction, which can replace the traditional process of riprap and silt compaction filling, solve the problem of insufficient coastal stones and damaging mountains, reduce the transportation of a large number of stones, and achieve the effect of energy conservation
