Mechanism and Engineering Characteristics of Expansive Soil Reinforced by Industrial Solid Waste: A Review

Expansive soils exhibit detrimental swelling and shrinking characteristics in response to variations water content, posing a threat engineering safety. Utilizing industrial solid waste for improving the properties of expansive soil presents promising solution due its low pollution high recoverability. This paper reviews progress research on various wastes stabilizing soil. The review comprehensively discusses microscopic mechanism waste-stabilized soils, as well their impact compressive strength, shear, compaction characteristics, consistency, shrinkage properties, durability soils. addition appropriate curing agents or combination with other materials can enhance strength soil, mitigate volume changes, improve stability mechanisms stabilization by involve cation exchange, flocculation-agglomeration, pozzolanic reaction, carbonation. Additionally, characterization analysis reveals that formation C-S-H C-A-H is primary contributor improvement geotechnical properties.
