各種 纖維補强콘크리드 强度特性에 관한 硏究 = A Study on Strength Properties of Various Kinds of Fiber Reinforced Concrete

다국어 초록 (Multilingual Abstract)

This study aims at investigating the strength properties of fiber reinforced concrete. Specimens were made from concrete reinforced by various kinds of fiber and the failure test was performed.
The results analyzed are as follow:
1. As the fiber content was increased, the flexural strength of various kinds of fiber reinforced concrete was increased and the order of an increasing rate was steel fiber, glass fiber, vinylon fiber and carbon fiber.
2. As the fiber content was increased, the slump of various kinds of fiber reinforced concrete was increased and the order of an increasing rate was steel fiber, glass fiber, vinylon fiber and carbon fiber.
3. As the fiber content was increased, the air of various kinds of fiber reinforced concrete was increased. Especially in case of 1% fiber content, the order of an increasing rate was glass fiber, carbon fiber, vinylon fiber and steel fiber.
4. As the fiber content was increased, the flexural strength and the toughness index of the vinylon fiber reinforced concrete was increased and the increasing rate of the toughness index was still larger than that of the flexural strength.
