Mechanical and thermal behaviors comparison of basalt and glass fibers reinforced concrete with two different fiber length distributions

Sadık Alper Yıldızel



This paper deals with the mechanical and thermal behavior of glass and basalt fiber reinforced concrete. Two different composites were studied containing either basalt or glass fibers. Fiber ratios were selected as 1%, 1.25% and 1.5% for glass fiber; 0.3%, 0.4% and 0.5% for basalt fibers. Fiber length was preferred as 12 mm and 24 mm. The addition of basalt fiber had very limited effect on the compressive, flexure and thermal conductivity properties compared to the glass fiber reinforced composite. The results also showed that composites having fibers with the length of 12 mm had better mechanical properties. Heat transfer simulation of the composites were also conducted. It was obtained that both fibers with the length of 12 mm had very close results on the heat transfer studies.
