| Abstract |
This study investigates the effect of length and contents of Nylon fiber on the engineering properties of concrete. According to the results, an increase of Nylon fiber reduced the fluidity of fresh concrete, which indicated the overuse of Nylon fiber in concrete should be considered. Using fiber resulted in an slight increase of air content and an dramatic decrease of the bleeding capacity which affected the retardation of setting time. For the compressive strength, fiber in concrete did not significantly affect the strength properties in comparison to that of control concrete. However, if it highly revises the strength value considering increase of air content, the final strength of concrete using fiber will be slightly over ride the control concrete. Impact resistance performance of concrete had the largest value in 0.6kg/m³ of fiber content, showing radial cracks. The use of Nylon fiber in concrete did not affect the reduction of drying shrinkage. |
