Stabilization of Clayey Soils Using Non-Traditional Aggregates: A Review

The bibliographic review carried out contemplated the studies performed for the chemical stabilization of clayey soils, which can be problematic due to their deficiency in physical and mechanical properties in construction. The studies included in the following article were born from the initiative to seek new alternatives to the use of cement and lime, particularly in the reduction or elimination of their use as traditional stabilizers, as well as to better manage the disposal of industrial waste. The incorporated studies evaluated stabilization by geopolymerization, reinforcement, use of common additives with other aggregates and residues. Stabilization effectiveness is measured primarily by results in physical properties such as optimum moisture content (OMC) and maximum dry density (MDD), both obtained through compaction tests and mechanical properties through tests such as unconfined compressive strength (UCS) and bearing capacity (CBR). To a lesser extent, the study of improvements related to durability, flexibility, permeability, among others, is also contemplated; studies, despite improving the main properties of the soils, deepened their research to obtain more information on the stabilization of clayey soils.
