Abstract:
In the current study, the effects of two types of additive for the soil (i.e. lime/cement) on the geotechnical and engineering properties of a soil are studied. The results of the study indicate that optimum moisture content, maximum dry unit weight and plasticity index are affected by the addition of cement or lime. Also cement treatment result in increase of unconfined compressive strength (UCS) of the soils significantly. Whereas the test results indicate that there is an optimum of lime content so that the addition of a few percentage of lime results in increase of unconfined compressive strength. Generally, improvement in mechanical behaviours of the soil due to cement treatment was noticeably higher than lime treatment. Also the results of tests show that the change of UCS of the specimens with the initial water content and curing time is significant, so that decreasing of initial water content or increasing of curing time results in increase of USC of the specimens. Also, the current study sought to characterize the relationship between secant modulus (E50) and UCS, curing time and cement or lime content.
