Laboratory Investigation on the Effect of Lime on Compressibility of Soil
MetadataShow full item record
Settlement and heave of soils is known as critical problems in civil engineering projects. In order to control this problem, were indicated several technique. Soil stabilization with a binder such as lime is one of the most regular methods. This paper presents a series of laboratory test for investigation and evaluation of lime effect on the compressibility and swelling properties of soil. In this study, the compression index, swelling index, coefficient of consolidation and initial void ratio of one un-stabilized sample and six stabilized samples with variation of lime additives were investigated. Generally, the results of this study indicate that lime stabilization could improve consolidation and swelling behaviour ofsoil, which could reduce the coefficient of consolidation, initial void ratio of soil by adding additives. It was also observed the divers result that was shown the different rate of stabilization effectivity onconsolidation and swelling properties of soil.
