摘要

Clayey soils are stabilized with various dosages of cement kiln dust, volcanic ash and their combinations. The influence of stabilizers is evaluated through Atterberg limits, standard Proctor compaction, uncon-fined compressive strength, splitting tensile strength, modulus of elasticity and California bearing ratio (CBR) tests. The durability properties of 14 stabilized soil mixtures are also investigated by studying the influence of water immersion on strength, water sorptivity and drying shrinkage. Correlations between strength, modulus of elasticity and CBR are also established. Developed stabilized soil mixtures have shown satisfactory strength and durability characteristics and can be used for low-cost construction to build houses and road infrastructures. The use of stabilized soils with locally available soils, volcanic ash and cement kiln dust can provide sustainability to the local construction industry.
