In this study, uniaxial compressive strength values of a sand type soil reinforced with polypropylene fiber and silicate-based resin additives with different amounts were investigated. Micro grid fiber (MGF) was tested as a new polypropylene fiber additive in the experiments to compare it with a widely used polypropylene fiber type geosynthetic product used in soil fill improvement applications. According to the findings obtained from the uniaxial compressive strength (unconfined compressive strength) tests, it was determined that the new MGF type fiber usually increased the strength values at higher rates in comparison with the conventional fiber product. As another outcome, it was found that target strength values can be supplied by using less resin amounts for the specimens with fiber additives. It was determined that proper strength improvements can be obtained more economically by the fiber additive use together with the resin, rather than the resin added mixtures without the fiber.

Farklı lif türleri ile güçlendirilmiş silikat bazlı reçine katkılı kum numunelerinin tek eksenli sıkışma dayanımı değerleri üzerine deneysel bir çalışma

Öz

Bu çalışmada, farklı oranlarda polipropilen lif ve silikat bazlı reçine katkı ile güçlendirilmiş kum türü bir zeminin tek eksenli sıkışma dayanımı değerleri incelenmiştir. Toprak dolgu uygulamalarında kullanımı yaygın olan bir polipropilen lif türü geosentetik ürünle kıyaslanması amacıyla deneylerde yeni bir polipropilen lif katkı olarak mikro hasır lif (MHL) test edilmiştir. Tek eksenli sıkışma dayanımı (serbest basınç mukavemeti) deneylerinden elde edilen bulgulara göre, MHL türü yeni lif ürünlerin geleneksel life kıyasla çoğu kez dayanım değerlerinde daha yüksek oranlarda artış sağladığı belirlenmiştir. Ayrıca, lif kullanımı ile kum türü zeminlerin istenilen dayanım değeri artışlarının daha az reçine kullanılarak sağlandığı görülmüştür. Lif katkının reçine ile birlikte kullanılması yolu ile lif içermeyen reçineli karışımlara kıyasla daha ekonomik olarak hedef dayanım değerlerine sahip olunabildiği belirlenmiştir.
