Determination of energy absorption capacity of fiber reinforced sprayed concrete

Abstract

The paper presents experimental research performed on fiber reinforced concrete slabs. For the preparation of the concrete elements, three different dosages of polypropylene fibers were used. The size of the specimens and the test methodology were established according to the SR EN 14488-5 - Testing sprayed concrete. Part 5: Determination of energy absorption capacity of fiber reinforced slab specimens. The slabs were tested in the Central Laboratory of the Faculty of Civil Engineering, Cluj-Napoca, using a flexural frame and the Advantest 9 console, capable of applying load in displacement control. Using the area under the load-displacement diagram, the energy absorption capacity of the fiber reinforced slabs was determined, at the age of 28 days.
