Distilled spirits lees ash as cement additive

The voluminous generation of distilled spirits lees (DSL) in China presents a challenge for proper disposal and potential environmental pollution. In an effort to address this issue, study aimed find resourceful solution DSL utilization. application incinerated rice husk ash as mortar supplementary material cement provides innovative the DSL. Five samples (DSLA) were produced using both muffle furnace (MF) fluidized bed (FB) combustion at different temperatures. properties DSLA characterized through measurements specific surface area observations scanning electron microscopy (SEM). Mortar specimens prepared by replacing 10% with DSLA, strength tests conducted. SEM results revealed crisscross mesh structures samples. Additionally, findings indicated strong connection between areas micromorphology. work, all samples, except one FB 800 °C, could improve compressive flexural strengths suitable employment additives.
