Abstract

This paper deals with the mechanical performances of glass fiber reinforced cementitious composites made with industrial
punching scrap. Two types of scraps with diameters of 5 mm and 7 mm were used in the production of cementitious
composite. The glass fibers were added at the ratio of 3 % by weight, and scrap were mixed with the weight ratios of 1%, 1.5%
and 2%. Pressure, flexural strength, and shrinkage tests were carried out on the produced samples. In addition, freezing and
thawing effects were also investigated. According to the results of the study, it was found that using scrap 1.5% by weight
improves the properties of the pressure and flexural strength properties of the composites. It was also observed that using scrap
2% by weight waste reduces the effects, when the shrinkage behavior was examined.

Endüstriyel Delme Artığı ile Üretilmiş Cam Elyaf Takviyeli Çimento Bazlı Kompozitlerin Mekanik Özellikleri

Abstract

Bu çalışmada endüstriyel delme artıkları ile üretilmiş cam elyaf takviyeli betonların mekanik performansı ele alınmıştır.
Çapları 5 mm ve 7 mm olan iki tür zımba ile delme artığı kompozit üretiminde kullanılmıştır. Cam elyaflar ağırlıkça %3
olarak, delme artıkları ise yine ağırlıkça %1, %1,5 ve %2 olarak kompozit karışımlarına eklenmiştir. Üretilen numuneler
üzerinde basınç, çekme dayanımları ve büzülme testleri gerçekleştirilmiştir. Ayrıca, donma ve çözünme etkisi de incelenmiştir.
Çalışma sonuçlarına göre zımba ile delme artığının ağırlıkça %1,5 oranında kullanılmasının kompozitlerin basınç ve çekme
gerilmeleri özelliklerini iyileştirdiği ortaya çıkmıştır. Büzülme davranışı incelendiğinde ise ağırlıkça %2 oranında delme artığı
kullanılmasının bu davranış altındaki etkileri azalttığı görüşmüştür.
