Strength Properties of Low Plasticity Clayey Soils Improved with Marble Dust and Scrap Tire
Journal Title: Doğal Afetler ve Çevre Dergisi - Year 2018, Vol 4, Issue 2
Abstract
Climatic changes negatively affect geotechnical and technological properties of engineering structures (especially as basic and substructure material). Various studies have been made towards decreasing this negative situation by mixing different additives in cohesive soil. In this study, the changes in strength of low plasticity red clayey soil improved with marble dust and scrap tire pieces were examined. Strength values of red clayey soil samples with the addition of 0.5%, 1%, 2% scrap tire pieces and 5%, 10%, 15%, 20% marble dust were determined on 0 (3h), 1, 7, 28 days and at +21oC. Out of these data, it was detected that the highest strength values were the red clay sample modified by adding 0.5% (2.00 mm) scrap tires and 5% marble dust after 28 days’ cure. This mixture was subjected to the freeze-thaw test. As a result, it was found that the strength of the improved clay unit and the main material reinforced with the addition of 0.5% (2.00 mm) waste tire and 5% marble dust were decreased by 5.1% and 28.7%, respectively. The resistance of the clayey soil reinforced with marble dust and waste tire pieces was significantly improved when compared to the main material.
