Effect of Mixing Method on Mechanical Properties of Fiber Reinforced Concrete

다국어 초록 (Multilingual Abstract)

Fiber reinforced concrete (FRC) has been successfully used to enhance the flexural toughness of concrete. As fibersare randomly oriented in FRC, they sometimes produce clumps that reduce the mechanical performance, and a properlychosen mixing protocol can be a way to minimize this problem. In this research, the effects of mixing method on themechanical properties of FRC were investigated. The compressive strength, flexural strength, and flexural toughnesswere measured using three different mixing methods. It was shown from the results that the compressive strengthand peak flexural load were not affected by changes in mixing method. However, in terms of flexural toughness, thechanges in mixing method clearly affected the flexural toughness of FRC. The truck-mixed FRC outperformed twopan-mixed FRCs.
