Testing of Concrete and Fibre Reinforced Concrete in Uniaxial Tension

Article Preview

Abstract:

The paper deals with an investigation of tensile properties of concrete and fibre reinforced concrete using the test in uniaxial tension. This arrangement is technically more difficult compared to the commonly used bending test, but allows easier determination of strength-deformation parameters of material. The advantage of the test is the possibility of direct analysis of the post-peak part of the stress-strain diagram in tension. The article describes the recommended test arrangement and analyzes methodology of loading. Attention is focused on the critical phase of the loading process and subsequent evaluation of results. In the experimental research was compared strength and corresponding strain of specific fibre reinforced concrete, obtained in three-point and four-point bending test, and the uniaxial tension test. The results of this comparative study are presented in the conclusion.
