Study on the influence of steel fiber content on the properties of ultra high performance fibre reinforced concrete – UHPC

Abstract

ABSTRACT:

This paper presents research results on the role and influence of the content dispersed steel fiber reinforcement in ultra high performance fibre reinforced concrete – UHPC. Through testing the physical and mechanical properties of the UHPC and UHPC blends, it is possible to provide reference data on the selection of the appropriate fiber content for the calculation of the composition and the UHPC mixer to ensure that the most optimal level of workability and mechanical properties.

Keywords: Ultra high performance fibre reinforced concrete – UHPC, dispersed steel fiber, heat moisture curing, flow, compressive strength, tensile strength, flexural strength, elastic Modulus and Poisson’s.
