- Synopsis
- In recent years, the applications of short polypropylene fibers for concrete structures have been increasing for purposes such as the prevention of fall out of concrete pieces from structures and of concrete spalling due to fire exposure. Based on the background, on March 20, 2015, the Japanese Industrial Standard for polypropylene short fibers was established for users and manufacturers. This report provides an overview of the published standard for polypropylene short fibers and difficulties in establishing the standard. This report also introduces the characteristics such as fiber types, linear density, the quality and the effect of the use of fibers in concrete.
