Alternatif Atıkların Kullanımı ile Üretilen Polipropilen Lif Takviyeli Kompozitlerin Mekanik Özelliklerinin Araştırılması
Öz
Madencilik faaliyetleri nedeniyle oluşan atıkların bertaraftı veya depolanması konusunda bugüne kadar çeşitli çalışmalar yapılmıştır. Gelişen teknoloji ile betonda agrega yerine alternatif ürünler kullanılmaya başlanmış ve agrega yerine kullanılan alternatif ürünlere fiber ilavesinin etkisi incelenmiştir. Yapılan çalışmaların en yaygınları kiriş numune üzerine yapılan eğilme dayanım testleridir. Bu çalışmada betonda kullanılan agrega yerine eşit hacimce madencilik işlemleri sonucu oluşan katı atıklar (bakır madencilik atığı, mermer atığı) ve uçucu kül kullanılmıştır. Bu katı atıkların kullanılması ile oluşturulan karışıma 4-6 kg/m3 polipropilen lif katılarak 40×40×160 mm boyutunda kiriş numuneleri dökülmüştür. Kiriş numuneler üzerinde; liflerin, ultrases geçiş hızı, eğilme ve basınç dayanımlarına etkisi incelenmiştir. Yapılan çalışmalar sonucunda liflerin basınç ve eğilme dayanımına olumlu etki yaparken, betonun su emme oranlarını ve yoğunluklarını etkilemediği belirlenmiştir. Son olarak ultrases geçiş hızının lif miktarı arttıkça azaldığı görülmüştür.

The Investigation of Mechanical Properties of Polypropylene Fiber-Reinforced Composites Produced With the Use of Alternative Wastes
Öz
Various studies on the disposal or storage of the wastes generated due to mining activities have been carried out until today. With the developing technology, the use of alternative products instead of aggregates in Composite and the effect of fiber addition were investigated. The most common of these studies is the bending strength tests on the beam sample. In this study, solid wastes generated by mining operations were used instead of aggregate used in Composite. Beam samples were poured with the dimensions of 40×40×160 mm by adding 4-6 kg/m3 polypropylene fiber to the mixture obtained by using these solid wastes; then, its effects on ultrasonic pulse velocity test, tensile test, and compressive strength tests were conducted. According to the results of these tests, it was found that the fibers had a positive effect on compressive strength and bending strength. Also, it was found that water absorption rates and densities did not have an effect, while the ultrasonic pulse velocity decreased with increasing fiber content.
