This study examines the durability of self-consolidating lightweight aggregate concrete (SCLAC) made from dredged silt from reservoirs in South Taiwan by chloride penetration, electrical resistivity, and sodium sulfide solution. Analysis with a densified mixture algorithm demonstrates that a lower water-to-binder ratio results in a higher compressive strength, smaller number of cracks, lower chloride penetration. and better ultrasonic pulse velocity. The results indicate that self-consolidating lightweight aggregate concrete made of dredged reservoir silt has good hardening and durability characteristics.
