✦ Synopsis

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 waterto-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.

This study investigates the properties of self-compacting glass concrete (SCGC), where liquid crystal glass sand (0%, 10%, 20%, and 30%) is used in place of aggregates. The results indicate that the slump flow of self-compacting glass concrete (SCGC) increases with higher glass sand content. Additio
