Abstract: This study investigated the improvement in a type of sand using a geopolymer made of recycled glass powder (RGP) as the base material and sodium hydroxide (NaOH) as the alkaline activator. Using maximum uniaxial compressive ...

Abstract: The growing population in the modern world has resulted in an increase in waste generation and stockpiles. There have been increasing concerns on how to sustainably reuse wastes in civil and geotechnical engineering ...

Abstract: Utilizing natural expansive clays that are available on-site as sewer trench backfill can cause destructive deformations due to volume changes, which are caused by seasonal climatic changes. Such deformations result in ...

Abstract: Sewer infrastructures that are backfilled with available onsite expansive soils may be exposed to damages due to seasonal ground movements. Therefore, for deep excavated trenches located in nontrafficable areas, the ...
