This study is aimed at discussing on the typical geotechnical engineering characteristics of sludge dredged from lakes in Hanoi city, which have strong demand to be dredged for environmental urban. Based on which, the possibility of recyclability as filling material will be discussed. Sludge samples were collected from “West Lake” and “Hoan Kiem Lake”. A series of laboratory tests for analyzing the typically physical and chemical characteristics has been conducted. The X-ray diffraction tests (ASTM C114) and plasma spectrum analyzer tests (TCNB-ICP 01/04) were also carried out to investigate the chemical components of the muds. The test results show that the chemical components meet the National technical regulation on hazardous waste threshold and they can be disposed as normal fill. Overview on the experiences of cement treated soil in Japan reveals that the muds dredging from lakes in Hanoi City have high possibility for recycling as filling material.
