电石渣改良过湿黏土的物理力学试验研究
Experimental study on physical and mechanical properties of over-wet clayey soils stabilized by calcium carbide residues
摘要
Abstract
The calcium carbide residue (CCR) is utilized to improve the over-wet clayey soils,which is used as subgrade materials in highway construction.A series of laboratory tests on moisture content,particle distribution,compaction,unconfined compression strength,modulus of resilience and wetting-drying cycle are carried out to study the mechanical properties of CCR-stabilized soils and lime-stabilized soils.The binder dosages are 4％,6％,8％,and 4％,6％ for CCR and lime respectively.The results indicate that the CCR has higher specific surface area,pH and fine particle content.Accordingly,the CCR-stabilized soils have greater physical performance than the lime-stabilized soils in terms of particle size distribution,plasticity index,the maximum dry density and the optimum moisture content.Additionally,the mechanical performance of CCR-stabilized soils is greater than that of the lime-stabilized soils,including the unconfined compressive strength,CBR,modulus of resilience and water durability.关键词
