Effects of curing time and freeze–thaw cycle on strength of soils with high plasticity stabilized by waste marble powder

This paper presents the experimental study on stabilization of fine-grained soils using waste calcitice marble powder (CMP) and dolomitic marble powder (DMP). Unconfined compressive strength (UCS) tests were conducted on both the pure and stabilized soil specimens with the percentages of 5, 10, 20,...

Description
Summary:This paper presents the experimental study on stabilization of fine-grained soils using waste calcitice marble powder (CMP) and dolomitic marble powder (DMP). Unconfined compressive strength (UCS) tests were conducted on both the pure and stabilized soil specimens with the percentages of 5, 10, 20, 30, and 50% waste marble powder (MP) by weight. The soil specimens mixed with two types of waste MP were cured for 7, 30, and 60 days and also subjected to freezing and thawing with 1, 3, 5, 7, and 11 cycles to investigate the effect of curing time and freezing–thawing on unconfined compressive strength ( q u ) and undrained elastic modulus ( E u ). Besides, mass losses (ML) of soil specimens were calculated after freezing–thawing cycles. According to the test results, the values of q u and E u of stabilized soil specimens increased sharply at waste MP content of 5% and then decreased with increasing of MP in highly plastic silt (MH) with plasticity index of 21. q u and E u increased with curing time dependent on the waste marble type and content in both soil type of specimens. As a result of this study, the waste MP contributed the fine-grained soils more resistant to freezing–thawing.
