Abstract
Over the past several years, fiber reinforced concrete (FRC) is increasingly used. It increases the concrete durability. It reduces crack growth and increases flexural and tensile strength. FRC is considered suitable construction material for Liquid retaining structures (LRS).
In this study the increase in flexural tensile concrete strength and in the modulus of rupture are studied to increase code limits related to initiation of cracking and satisfaction of serviceability.
This paper presents the results of an experimental study involving five simply supported notched beams with 0.9kg/m³, 1.8kg /m³, 2.7 kg/m³, and 3.6 kg/m³ of steel fibers Subjected to three - point bending tests. Five tests on prismatic beams with 150x150x700mm reinforced with four different steel fibers contents were conducted.
The experimental investigation includes the load - deformation behavior, the cracking load, and flexural capacity. The results were compared to concrete specimens with no steel fiber.
A comparison is made between the ACI, BSI, ECP codes to compare the evaluated strength and experimental values. The results indicate that increasing the steel fiber content in concrete led to higher ultimate loads, higher first cracking load and better crack distribution resulting in better performance under serviceability conditions.
