Preventive effect on spalling of UFC using jute fiber at high temperature

Abstract

In this study, we examined the relationship between spalling behaviour and spalling ratio of UFC with three kinds of short fibers (jute, polypropylene, water-soluble polyvinyl alcohol) at high temperature. The heating temperatures were 400 °C and 600 °C. Although the specimen with jute fiber dosage of 0.19% by volume was occurred explosive spalling, the damage of specimen was slightly small. It appears that the addition of jute fiber to UFC is effective for preventing spalling.
