Testing of Deformation Properties of Fiber Reinforced Cement Composites

Abstract

It is a known fact that fibers are usually added to cementitious composites (concrete and mortar) in order to improve some of their physical-mechanical properties, such as: tensile and flexural strength, impact resistance, shrinkage, freeze-thaw resistance, durability, etc. On the other hand, improvement of deformation properties (such as ductility or elasticity modulus) of such composites can be equally or even more important. Evaluation of ductility (or toughness) of fiber reinforced cementitious composites is usually related to the area under the σ-ε diagram obtained during different static or dynamic tests. This paper presents the experimental testing results of deformation properties of fiber reinforced composites made with different types and quantities of fibers – when subjected to compression.
