Preliminary Research on Particle Size Analyses Method of the Quicklime-Stabilized Dredged Material

Abstract:

The paper presents a comparative study of particle size analyses of quicklime-stabilized dredged material (LSDM) by combined sieve-hydrometer method (SHM), laser diffraction method (LDM) and sieve method (SM). After analyzed the testing processes and compared the results comprehensively, some conclusions can be conduction. Adopting SHM and LDM to test the particle size of LSDM, not only break the structure unit of soil, but also change its property due to the pure water used as disperser. In addition, the severe flocculation, which attributed to the dissolvable salt in soil introduced by quicklime can’t be drainage effectively, result in the abnormal particle size distribution (PSD) curves produced by the SHM. Therefore, SHM and LDM are not suitable for the particle size analyses of LSDM. SM, without deteriorating the unit structure of aggregates and altering the properties of soil, should be adopted as the most suitable method for LSDM.
