Geotechnical and Microstructural Mechanisms Associated with Valorization of Waste Phosphogypsum in Lime-Treated Expansive Soil Stabilization

Abstract

Abstract In the present study, phosphogypsum (PG), a by-product from the fertilizer industry, has been utilized to stabilize expansive soil. In order to enhance the pozzolanic activity of PG stabilized soil, 3% and 6% of hydrated lime have been used as a ...
