摘要
Concrete is the most important building material of our century. Concrete, which works under compression, is a brittle material with a low tensile strength. The addition of various types of fibers to concrete increases its ductility. Basically, the use of fibers is intended to increase crack control and ductility. Today, the use of various fibers is becoming widespread. It may be necessary from time to time to reassess and evaluate newly completed reinforced concrete buildings or those buildings still under construction as well as those in existence for years. The concrete strength of a building can be determined by using non-destructive methods or by taking cores. It is an inevitable necessity that the number of cores be limited because taking cores may lead to a weakening of the structural members. The aim of this study is to compare the mechanical properties of concrete with steel fiber, polypropylene fiber and with both in combination and to investigate the effects of using these fibers on the mechanical properties of concrete. Another objective of the study is to compare concrete compressive strength as determined by the destructive method with that determined by a non-destructive method.
