EFFECT OF STEEL FIBERS ON MECHANICAL PROPERTIES OF CONCRETE

Abstract

The concept of rein forcing concrète with discontinuous fibres in the volume is a variant of the concept of using fibres to improve the mechanical behaviour of brittle materials in order to maintain the stability of the structure. This variant, known in the field of construction materials as fibre concrete, has been the subject of growing interest in industrial countries over the last few decades, going well beyond the stage of mere technical curiosity, over the last few decades in industrial countries, has been the subject of growing interest, which has gone far beyond the stage of mere technical curiosity, and has been the subject of studies focusing more and more on the analysis and modelling of this elementary combination in order to reach the stage of standardised, simplified and safe use. As part of this research, we need to study the mechanical characteristics of concrete, in particular compressive strength and tensile strength, in order to ensure the durability and longevity of structures under the effect of différent stresses. We need to improve these mechanical performances by incorporating steel fibres.
