| Summary: | Dredged marine soils (DMS) are considered as wastes and are currently
not being recycled. Solidification of DMS needs to be undertaken before the
materials can be reused.This study focused on the development of strength of
three solidified fine-grained DMS which are high plasticity clay (CH), high
plasticity silt (MH) and low plasticity silt (ML) admixed with cement and bottom
ash. This paper discussed the effect of water-binder ratio and curing period on the
strength development of the solidified DMS. The results show that the strength
increased with prolonged curing. The strength increased when the water-binder
ratio was decreased. CH samples with water-binder (w/b) ratio =1 has the highest
strength that are up to 4.7 MPa. Optimal w/b ratio for solidified DMS is w/b=3. |
