Strength Properties of Low Plasticity Clayey Soils Improved with Marble Dust and Scrap Tire

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 +21^oC. 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.

Mermer Tozu ve Atık Lastik ile İyileştirilen Düşük Plastisiteli Killi Zeminlerin Dayanım Özellikleri

Abstract

İklimsel değişiklikler, mühendislik yapılarının (özellikle temel ve alt temel malzemesi olarak) geoteknik ve teknolojik özelliklerini olumsuz olarak etkilemektedir. Bu olumsuz durumun kohezyonlu zeminlerde çeşitli katkılar karıştırılarak azaltılması yönünde çeşitli çalışmalar yapılmaktadır. Bu çalışmada, mermer tozu ve atık lastik parçalarıyla iyileştirilmiş düşük plastisiteli kırmızı killi birimin dayanımındaki değişimler incelenmiştir. Kırmızı kil birimine  % 0.5, % 1, % 2 atık lastik ve  %5, %10, %15, %20 mermer tozu ilave edilerek 0 (3 saat), 1, 7, 28 gün ve +21^oC’deki dayanımları belirlenmiştir. Bu verilerden 28 günlük kür sonrası %0.5 (2.00 mm) atık lastik ve %5 mermer tozu katkısıyla iyileştirilen killi birimin en yüksek dayanım değeri verdiği belirlenmiştir. Bu karışıma donma-çözülme deneyi uygulanmıştır. Sonuçta, %0.5 atık lastik (2.00 mm) ve %5 mermer tozu ile iyileştirilen killi birimin dayanımında %5.1, ana malzeme olan kilde ise %28.7 oranında azalma meydana gelmiştir. Mermer tozu ve atık lastik parçaları ile iyileştirilen killi zeminin dayanımında, ana malzeme ile mukayese edildiğinde belirgin bir iyileşme sağlanmıştır.
