Behavior analysis of high strength concrete containing macro-polymeric fibers based on workability and mechanical properties

Abstract: The main purpose of fiber reinforcement in concrete is to increase the post-cracking resistance of the composite, which reflects on toughness gain, being steel fibers traditionally used for this purpose. In recent years, an alternative to the steel fibers has emerged in the market for conc...

The workability was evaluated by the slump test and the mechanical properties were evaluated by the tests of compressive strength, Barcelona, flexure of prisms and punching of plates. It was found that, depending on the property to be analyzed, the increase of the macro-polymeric fiber content may be unfeasible. In the flexural test in prisms, for example, most parameters evaluated showed no significant changes when increasing the fiber content.
