© 2021, TUBITAK. All rights reserved.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.
