Experimental Study of Flexural Tensile Strength of Sand Concrete Plates Reinforced with Metallic Fibers

This paper presents the findings of an experimental study of sand concrete plates reinforced with metallic fibers (BSFM) mixes with respect to a reference sandcrete without fibers (BST) that establishes a benchmark for the BSFM mixes. The performed tests are based on the characteristics of fresh sandcrete (density, slump) and on the mechanical behavior of slabs in centered flexion. It was concluded that the metallic fibers improves the tensile strength, rigidity and durability characteristic after cracking. These characteristics are at an optimum for a sand concrete reinforced with metal fibers (BSFM) with 30kg of fibers per m3 of sand concrete.
