Solidification Study of an Organic Fine Sediment Using Geopolymer Binders Properties
Publication: International Journal of Geomechanics
Volume 23, Issue 10
Abstract
The present study addresses the characterization of long-term and durability properties for employment in road subgrade construction of geopolymer-treated sediments. Four mixtures are presently selected based on a previous study: untreated sediment, sediment treated with 2% hydraulic lime (L) and 7% ordinary Portland cement OPC, and two geopolymer-treated mixtures using 5% and 10% of ground granulated blast furnace slag/sodium silicate-based geopolymers. Long-term properties are investigated through unconfined compressive strength and tensile strength tests. The resistance of designed materials to weathering conditions is tested through freeze–thaw cycles, humidification–drying cycles, and immersion in water. Sediments treated using 10% geopolymer binder are resistant to weathering conditions and showed long-term properties superior to those of sediments treated using an L/OPC mixture.
