Abstract
In this study, the effects of macro-synthetic fiber (MSF) ratios and various temperatures on the flexural performance of MSF-reinforced concrete were investigated. MSF-reinforced concrete was produced in the C40 strength class, which is widely used in industrial concrete applications. The effects of fiber content and temperature variations on the flexural strength and toughness of MSF-reinforced concrete were analyzed. In this context, flexural specimens were produced by replacing 0.5%, 1.0%, 1.5%, and 3% MSF by volume with concrete instead of aggregate. The specimens were tested using a four-point flexural test at a negative temperature (-5 degrees C), ambient temperatures (20, 50 degrees C), and non-ambient temperature (90 degrees C). In addition, pull-out tests were applied to the fibers embedded in the concrete specimens to determine the bond performance between the MSF and concrete under different temperatures. The effective MSF content for the concrete was determined to be in the range of 1-1.5% according to the results of thermal performance, bending behavior, ductility, and workability factors. Although the flexural performance of MSF-reinforced concrete decreased relatively with the temperature increase, the results were promising at certain fiber volume ratios and ambient temperatures.
