    Effects of curing time and freeze-thaw cycle on strength of soils with high plasticity stabilized by waste marble powder
    (Springer, 2020) Aydin, Kemal; Sivrikaya, Osman; Uysal, Firdevs
    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.

    The Efficiency of Waste Marble Powder in the Stabilization of Fine-Grained Soils in Terms of Volume Changes
    (Springer Heidelberg, 2020) Sivrikaya, Osman; Uysal, Firdevs; Yorulmaz, Aysegul; Aydin, Kemal
    The recycling of waste marble powder (MP) for soil stabilization is still under research for geotechnical engineers, with the aim of improving poor soil properties. This paper investigated the effect of calcitic marble powder (CMP) and dolomitic marble powder (DMP) on the geotechnical properties of fine-grained soils. Consistency limits, linear shrinkage, expansion index, and one-dimensional consolidation tests were performed on non-stabilized and stabilized samples with 5, 10, 20, 30, and 50% of waste CMP and DMP to determine the efficiency of using waste marble powders in soil stabilization. The marble powder ratio which gave the best results was determined as 50% for both MH samples and CH samples. The laboratory test results showed that the waste marble powders were effective in soil stabilization by reducing the plasticity index from 49 to 26 for the CH samples and from 21 to 9 for the MH sample, expansion index from 45 to 20 for the CH sample and from 32 to 7 for the MH sample, swelling index from 0.0030 to 0.0012 for the MH sample, compression index from 0.013 to 0.010 for the MH sample, and linear shrinkage from 16.2 to 10.5 for the CH sample. The waste MP content and fine-grained soil type need to be taken into consideration in soil stabilization based on volume change.
