“…This shows an enhancement of 240% and 285% compared to the splitting tensile and flexural strengths of the control mix. On the other hand, the HT30 mix produced a higher flexural strength (>50%) than the fibre-reinforced NWC of the same density (2400 kg/m 3 ) (7,27). This has indicated the capability if the HT30 mix in compensating the weak tensile strength of conventional OPSC.…”

“…The studies on flexural behaviours of fibre-reinforced LWC becomes more complicated with different types of lightweight aggregate involved. From the past literature, the effect of fibres on the flexural performances of reinforced concrete beams showed a few common benefits by the incorporation of steel fibres, including reduced brittleness, enhanced crack resistance and moment capacity (21,(26)(27)(28). However, Meda, Minelli & Plizzari (29) had demonstrated that the fibre reinforcement can lead to a reduction in the ductility of reinforced concrete beams; while Qian & Indubhushan (26) and Wang & Belarbi (28) reported that steel fibres increased the displacement of beams at failure.…”

ABSTRACT:The utilization of lightweight oil palm shell to produce high strength lightweight sustainable material has led many researchers towards its commercialization as structural concrete. However, the low tensile strength of Oil Palm Shell Concrete (OPSC) has hindered its development. This study aims to enhance the mechanical properties and flexural behaviours of OPSC by the addition of steel fibres of up to 3% by volume, to produce oil palm shell fibre-reinforced concrete (OPSFRC). The experimental results showed that the steel fibres significantly enhanced the mechanical properties of OPSFRC. The highest compressive strength, splitting tensile and flexural strengths of 55, 11.0 and 18.5 MPa, respectively, were achieved in the OPSFRC mix reinforced with 3% steel fibres. In addition, the flexural beam testing on OPSFRC beams with 3% steel fibres showed that the steel fibre reinforcement up to 3% produced notable increments in the moment capacity and crack resistance of OPSFRC beams, but accompanied by reduction in the ductility. RESUMEN: Vigas de hormigón de alta resistencia con palma de aceite reforzados con fibras de acero. La utilización de cáscara ligera de palma de aceite para producir materiales duraderos y de alta resistencia ha llevado a muchos investigadores a su comercialización como hormigón estructural. Sin embargo, la baja resistencia a la tracción del hormigón de cáscara de palma de aceite (OPSC) ha obstaculizado su desarrollo. Este estudio tiene como objetivo mejorar las propiedades mecánicas y los comportamientos de flexión de OPSC mediante la adición de fibras de acero de hasta un 3% en volumen, para producir hormigón armado de fibra de palma de aceite (OPSFRC). Los resultados experimentales mostraron que las fibras de acero mejoraron significativamente las propiedades mecánicas de OPSFRC. En la mezcla OPSFRC reforzada con fibras de acero al 3% se obtuvieron las mayores resistencias a la compresión, resistencia a la tracción ya la flexión de 55, 11,0 y 18,5 MPa, respectivamente. Además, el ensayo de vigas flexibles en haces OPSFRC con fibras de acero al 3% mostró que el refuerzo de fibra de acero hasta 3% produjo incrementos notables en la capacidad momentánea y resistencia a la fisuración de los haces OPSFRC, pero acompañado de una reducción de la ductilidad.PALABRAS CLAVE: Árido; Hormigón; Refuerzo de fibras; Resistencia a la flexión; Propiedades mecánicas ORCID ID: S.

“…Padmarajaiah and Ramaswamy [9], Altunet. al [1], Özcan et. al [10], Hamid [3] and Marta Słowik and Tomasz Nowicki [11] used four points bending test rather than three points bending test in which the beam is longer than 1 m. However, Mujika [12] was found that the flexure modulus calculated on four points bending test without correction for both test methods is overestimated.…”

“…Altunet. al [1] concluded that the mechanical properties of concrete with 30 kg/m 3 steel fibre dosage is clearly better than concrete without steel fibre and concrete with 60 kg/m 3 steel fibre dosage. Chang and Chai [2] found that the initial crack load of SFRC beam with steel content between 1.0% to 1.5% volumes increased 2 or 2.5 times from the RC beam.…”

ABSTRACT:The introduction of steel fibres in concrete beam has been proposed as flexural cracks inhibitor. This research was conducted focusing on simply supported beam to determine the crack propagations in flexure by varying the steel fibre content placement in the beam. The 25 kg/m 3 steel fibre was chosen. Seven sets of 150×250×1000mm concrete beams consists of three RC beams with full steel fibrous concrete (SFRC), three RC beams with steel fibre placed within tension zone of the beam, three RC beams with steel fibre placed at the half of beam's tension zone, two conventional RC beams as control sample, one unreinforced concrete beam with full steel fibre, one unreinforced concrete beam with steel fibre at tension zone only and one unreinforced concrete beam with steel fibre at half of tension zone. The addition of steel fibre in the conventional RC beam showed that it inhibits the flexural cracks.

“…It becomes more popular in these recent years and expected to provide better physical and mechanical properties in concrete for structural purposes. The use of different types of fiber in a suitable combination may potentially improve the mechanical properties of concrete and result in synergic performance [6][7][8][9]. Addition of steel fiber generally provides contribution to the energy absorbing mechanism (bridging action), while nonmetallic fibers offer its ability to delay the formation of microcracks and avoid catastrophic breaking, and also has much lower density [9].…”

Lightweight concrete application in construction field is growing rapidly in these recent years due to its advantages over ordinary concrete. In this paper, pumice breccia which can be found abundantly in Indonesia is proposed to be utilized as the coarse aggregate. In spite of its benefits, lightweight concrete exhibits more brittle characteristics and lower tensile strength compared with normal concrete. On the other hand, fiber addition into concrete has become widely used to improve its tensile properties. Furthermore, the utilization of hybrid fiber in a suitable combination may potentially improve the mechanical properties of concrete. This paper experimentally examines the effects of hybrid polypropylene-steel fiber addition on some hardened properties of pumice breccia aggregate lightweight concrete. Five groups of test specimens with fixed volume fraction of polypropylene fiber combined with different amounts of steel fiber were added in concrete to investigate the density, compressive strength, modulus of elasticity, splitting tensile strength, and the modulus of rupture of the concrete mixtures. Test results indicate that hybrid fiber addition leads to significant improvement to the compressive strength, modulus of elasticity, splitting tensile strength, and the modulus of rupture of the pumice breccia lightweight aggregate concrete and meet the specification for structural purposes.
