Synergistic effects of ground granulated blast furnace slag and nano-silica on the consolidation, compressibility and microstructural behavior of high plasticity clay

Key Points

• Enhanced compressibility and consolidation of high plasticity clay were observed, leading to improved soil stability.
• The addition of ground granulated blast furnace slag and nano-silica significantly altered the microstructural behavior, indicated through specific tests.
• Assessment involved varying concentrations of additives to determine optimal performance parameters for soil improvement.
• These findings may enable more effective construction materials, highlighting the innovative use of industrial byproducts.
