Mechanical properties of ultra high performance fiber reinforced concrete (UHPFRC)‎

Abstract EN

The objective of this study is to examine the mechanical properties of Ultra High Performance Concrete using steel fibers.

Specimens are prepared for compressive strength, splitting tensile strength and flexural strength.

For the compression test four silica fume contents and three volumes of steel fibers are used in preparing the mixes.

Moreover, for the splitting tensile strength and flexural strength tests, one silica fume content, Two aspect ratios and two volumes of steel fibers are used.

Based on the results of this study, it is concluded that the addition of steel fibers results in a slight increase in compressive strength.

On the other hand, the addition of steel fibers has a positive impact on splitting tensile strength and flexural strength of concrete.
