In the proceedings of: GeoVirtual 2020: 73rd Canadian Geotechnical ConferenceABSTRACT: This study was conducted to develop a sustainable post-fire soil restoration strategy utilizing pulp mill fly ash (PFA) as soil stabilizer. Wildfire impacts on forest soil properties located in Okanagan region of British Columbia was initially assessed, and efficiency of PFA for post-fire soil stabilization was evaluated in terms of hydro-mechanical properties variations of burnt soil treated with PFA. Detailed microstructural examination of untreated and treated soil samples was also conducted to investigate the underlying stabilization mechanisms. The soil aggregate stability and water retention capacity of burnt soil were substantially improved with 10% PFA dosage after 28 days curing. Formation and deposition of new water stable cementitious compounds, predominantly consisting of calcium-silicate and magnesium bridges, were revealed in soil macropores attributed to soil restoration.
