INVESTIGATION THE COMBINED EFFECT OF BIOPOLYMER AND FIBER ADDITIVES ON STRENGTH AND POST FREEZING-THAWING STRENGTH OF CLAY

Abstract

Clay soils are known as problematic soils because they lose volumetric stability when they encounter water. Additionally, freeze-thaw phenomenon is an important parameter adversely affects the properties of soils. There are many improvement methods to improve the properties of clay soils to prevent such conditions. Soil improvement with additives is one of the commonly used methods. Among the additives, traditionally chemical materials (i.e. cement, lime) are used, while waste materials (i.e. fly ash) are also used. In recent years, considering environmental damage of these materials, researchers have been searched for materials that don’t cause carbon emissions. In this context, improvement with biopolymers, that called environmentally friendly, green polymers started to be studied. In addition to these, fibers are also used in soil improvement. In literature, the improvement of soils by biopolymers and fibers combined is a new topic. In this study, locust bean gum, a biopolymer, and polyester fiber, a synthetic fiber, were used in different percentages to investigate the strength and post-freeze-thaw strength of clay soil. As a result of the study, it was observed that combination of biopolymer and fiber improved the unconfined compressive strength and post freeze-thaw strength of clay soil more than fiber and biopolymer.

KİLİN MUKAVEMETİ VE DONMA-ÇÖZÜLME SONRASI MUKAVEMETİ ÜZERİNDE BİYOPOLİMER VE LİF KATKISININ ORTAK ETKİSİNİN ARAŞTIRILMASI

Öz

Kil zeminler, suyla karşılaştıklarında hacimsel stabilitelerini kaybettikleri için problemli zeminler olarak bilinmektedir. Ayrıca donma-çözülme olayı bu zeminlerin mühendislik özelliklerini olumsuz yönde etkileyen önemli bir parametredir. Kil zeminlerin bu gibi durumlara karşı özelliklerini iyileştirmek amacıyla birçok iyileştirme yöntemi bulunmaktadır. Katkı malzemeleri ile zemin iyileştirme yaygın olarak kullanılan yöntemlerden birisidir. Katkılar arasında geleneksel olarak kullanılan çimento, kireç gibi kimyasal malzemeler yer alırken uçucu kül gibi atık malzemeler de kullanılmaktadır. Son yıllarda bu malzemelerin çevreye verdikleri zarar göz önüne alınarak araştırmacılar tarafından karbon salınımına neden olmayan malzeme arayışına gidilmiştir. Bu bağlamda çevre dostu, yeşil polimerler olarak tabir edilen biyopolimerler ile zemin iyileştirmesi yaygın olarak çalışılmaya başlanmıştır. Bunlara ilaveten lifler de zemin iyileştirmesinde alternatif olarak kullanılan malzemeler arasında yer almaktadır. Literatürde biyopolimer ve liflerin bir arada kullanılması ile zeminlerin iyileştirilmesi ise yeni bir konudur. Bu çalışma kapsamında bir biyopolimer olan keçiboynuzu gam ile sentetik bir lif olan polyester iplik farklı yüzdelerde kullanılarak kil bir zeminin mukavemet ve donma çözülme sonrası mukavemet davranışı araştırılmıştır. Çalışma sonucunda, biyopolimer ve lifin bir arada kullanılmasının kil zeminin serbest basınç ve donma çözülme sonrası mukavemetini yalnız lif ve yalnız biyopolimer içeren kile göre daha fazla iyileştirdiği görülmüştür.
