Pozzolanic Activity of Municipal Sewage Sludge Ash and Its Potential Use for Soft Soil Stabilization
Sewage sludge is a by-product of wastewater treatment and is typically dewatered and incinerated to reduce its volume prior to landfill disposal. As the residue of incinerating sewage sludge, sewage sludge ash (SSA) can potentially be used in a number of alternative applications depending on its pozzolanic activity. This study first examines the pozzolanic activity of a SSA from a local wastewater treatment facility, Delaware County Regional Water Quality Control Authority (DELCORA) located in southeast Pennsylvania. The SSA was then investigated for possible use for soft soil stabilization. Various dosages of SSA (5%, 10%, 15%, 20%, 25%, and 30%) were utilized to quantify the pozzolanic activity of mortar mixtures. The SSA was found to be capable cementitious material at a dosage up to 10%. The SSA was then mixed with kaolinite clay to investigate its potential for soil stabilization. Unconfined compression strength tests were conducted on control and SSA-stabilized kaolinite clay.
