Abstract

In this paper, three types of concrete slabs against impact loading caused by drop weight were examined and compared. Type I, slabs without fibers, Type II slabs with uniform percentage of fibers (Steel, poly propylene and hybrid) through thickness and type III slabs with variable percentage of fibers through thickness. Results showed that usage of fibers, significantly increased impact resistance of type II and III slabs compared to type I slabs. This study indicated that the efficacy of the tested slabs influenced by three factors including fiber type, fiber percentage and the position of the layers. FUNCTIONALLY GRADED arrangement of layers such that outer layers had more percentage of fibers than inner layers, considerably increased energy absorption of type III slabs compared to Type II slabs while total amount of fibers used were the same. Also the results of the experiments showed that ultrasonic pulse velocity decreases with increasing fiber percentage and pulse velocity in FUNCTIONALLY GRADED slabs is variable through the thickness due to different amount of fibers in layers.
