ECO-FRIENDLY SOIL STABILIZATION USING WASTE FIBERS

Abstract

This study presents a comprehensive review of the potential use of various waste fiber, to enhance the properties of various types of soil, improving their strength and resistance to deformation. This approach represents a sustainable environmental benefit by reducing harmful emissions associated with traditional stabilizers like cement. The findings indicated that adding 0.75% coconut fiber waste (CCF) to clay resulted in a 135% increase in the unconfined compressive strength (qu) value and adding 1% of CCF improved CBR value by 94%. Adding 1% jute fiber (JF) significantly increased the California bearing ratio (CBR) and qu values, while decreased the swelling potential. Sisal fiber (SF) showed superior performance at 0.6-1% concentrations in enhancing shear strength. The addition of 1.5% of SF showed an improvement of 233% in qu value. Additionally, nylon fiber (NF) at concentrations of 1-1.5% was more effective in reducing swelling potential and increasing qu and CBR values, improving soil structure and deformation resistance.

ATIK LİFLER KULLANILARAK ÇEVRE DOSTU TOPRAK STABİLİZASYONU

Abstract

Bu çalışma, çeşitli toprak tiplerinin özelliklerini geliştirmek, mukavemetlerini ve deformasyona karşı dirençlerini artırmak için çeşitli atık liflerin potansiyel kullanımına dair kapsamlı bir inceleme sunmaktadır. Bu yaklaşım, çimento gibi geleneksel stabilizatörlerle ilişkili zararlı emisyonları azaltarak sürdürülebilir bir çevresel fayda sağlamaktadır. Bulgular, kile %0,75 hindistan cevizi lifi atığı (CCF) eklenmesinin, serbest basınç dayanımı (qu) değerinde %135'lik bir artışa neden olduğunu ve %1 CCF eklenmesinin CBR değerini %94 oranında iyileştirdiğini göstermiştir. %1 jüt lifi (JF) eklenmesi, şişme potansiyelini azaltırken, Kaliforniya taşıma oranı (CBR) ve qu değerlerini önemli ölçüde artırmıştır. Sisal lifi (SF), kayma dayanımını artırmada %0,6-1 konsantrasyonlarında üstün performans göstermiştir. %1,5 SF eklenmesi, qu değerinde %233'lük bir iyileşme göstermiştir. Ek olarak, %1-1,5 konsantrasyonlarındaki naylon lifi (NF), şişme potansiyelini azaltmada ve qu ve CBR değerlerini artırmada daha etkili olmuş, toprak yapısını ve deformasyon direncini iyileştirmiştir.
