Özet:

Comparison of concrete mixtures containing steel mesh, steel fiber and polypropylene fibers were evaluated in terms of toughness, flexural strength, compressive strength and split tensile strength. Five types of concrete were prepared with steel mesh, steel fiber and polypropylene fiber with the identical water/cement (w/c) ratio and the identical workability. 10x60x60 cm plates, 8x8x32 cm beams and 10x20 cm cylindrical concrete specimens were prepared. Compressive strength, split-tensile strength and toughness of the concrete specimens were determined at 7, 28 days of age and the results were compared. According to the results obtained from the tests, concrete made with steel mesh showed the best performance in panel tests. Also the results of the beam tests were compared with the plate test to determine the effectiveness of using beam test for toughness instead of plate test. The panel test was observed to be better for determining toughness than the beam test.
