Abstract:
This paper focuses on the effect of steel fiber volume content on the flexural resistance of highperformance fiber-reinforced concrete (HPFRC) through experimental work. Two bending parameters, including flexural strength and deflection capacity were investigated. Two HPFRC series embedded different fiber types and contents were as follows: series 1 (denoted HPFRC1), using long hooked steel fiber with volume content of 0.0%, 0.5%, 1.0%, and 1.5%, and series 2 (denoted HPFRC2) using short smooth steel fiber with volume content of 0.0%, 0.5%, 1.0%, and 1.5%. All flexural specimens with same dimensions of 40x40x160 mm were tested under static loading using a three-point bending scheme. Based on the experimental results, the flexural strength and deflection capacity of the HPFRCs were evaluated and discussed.This paper focuses on the effect of steel fiber volume content on the flexural resistance of highperformance fiber-reinforced concrete (HPFRC) through experimental work.
