Abstract

In recent years, especially for military structures in areas where terrorist attack incidents are frequent, studies on the development of explosion and rocket resistant concrete with high impact resistance have increased. One of the most important materials used for this purpose is polypropylene fibers. In the literature, studies with monofilament type PP fiber are limited. In this study, M12 monofilament type PP fiber with a diameter of 32 µ was added to concrete at different ratios, and changes occurring in the mechanical properties of concrete, such as shrinkage, flexural, compressive and impact strength, and microstructures were examined. It was determined that there was a 41% decrease in shrinkage, a reduction in compressive strength, a slight improvement in flexural strength, and up to 318% increase in impact strength as fiber addition increased. In the microstructural examinations, it was observed that fiber addition prevented disintegration by keeping cracked pieces together.

M12 Monofilament Tipi Polipropilen Lif Takviyeli Betonların Özellikleri

Abstract

Son yıllarda özellikle terörist saldırı olaylarının sık olduğu bölgelerdeki askeri yapılar için patlama ve rokete dayanıklı betonun yüksek darbe dayanımına sahip geliştirilmesine yönelik çalışmalar artmıştır. Bu amaçla kullanılan en önemli malzemelerden biri polipropilen liflerdir. Literatürde monofilament tipi PP elyaf ile yapılan çalışmalar sınırlıdır. Bu çalışmada; 32µ çapında M12 monofilament tipi PP lif, farklı oranlarda beton içerisine katılmış ve betonun rötre büzülmesi, eğilme, basınç ve çarpma mukavemeti gibi mekanik özelliklerinde meydana gelen değişimler ve mikroyapılar incelenmiştir. Lif katkısı arttıkça, rötre büzülmesinde %41 oranında azalma, basınç dayanımında düşme, eğilme mukavemetinde az miktarda da olsa iyileşme ve çarpma dayanımın da %318’ lik bir artış tespit edilmiştir. Mikroyapı incelemelerinde lif katkısının çatlayan parçaları bir arada tutarak dağılmayı engellediği görülmüştür.
