Abstract

Using dredged sediments as construction materials can alleviate the problem of sediment disposing, while properties have to be improved for corrosive environment. The effectiveness of using sodium bentonite and agent J(home-made agent) was investigated by means of laboratory tests to evaluate the compatibility of solidified sediment cubes in corrosive environment. Cube crushing strength (CCS) and water immersion tests were carried out. After curing the sediment, the undefined compressive strength of samples achieved 165% improvement after 7 days. The strength loss rate significantly dropped by 28.5% and 18.8% in acid or saline solution respectively. Therefore, this technique is worth popularizing for solidified performance improvement.
