“…The addition of steel fibers to concrete considerably improves its mechanical properties such as tensile and flexural strengths, ductility, and flexural toughness [6]- [8]. Steel fiber has the ability to excellent tensile strength, flexural strength, shock resistance, fatigue resistance, ductility and cracks arrest.…”

Waste tyres have been an increasing problem every year due to the increase in vehicle sales. In Indonesia, more than 50 million waste tyres were generated every year. However, materials in waste tyre such as textile and steel fibers, actually, can be used to improve the mechanical properties of the concrete. Recently, some researchers have been devoted to the utilization of steel fibers extracted from the waste tyre (SFEFWT) on the concrete. This study focuses on the investigation of SFEFWT effect on the concrete containing palm oil fuel ash (POFA). Steel fibers were extracted from waste tyres by manually cutting process and being cut to 1 inch (25.4 mm) length. A number of cylindrical and beam specimens of concrete containing 15% palm oil fuel ash by being partially replaced the weight of cement, with addition 0.25%, 0.50%, 0.75% and 1% SFEFWT were cast and tested. The mechanical properties such as compressive, tensile and flexural strengths at the age of 28 days are studied for having prepared the concrete. The results show that the addition of SFEFWT on the concrete containing POFA improves the concrete strengths, particularly the tensile and flexural strengths. The more percentage of SFEFWT content on the POFA concrete results in the higher increase in tensile and flexural strengths. In addition, the presence of SFEFWT contributes to give higher bonding on concrete to control the crack opening on the POFA concrete.

“…However, in comparison with long fibers, small fibers deliver a uniform dispersion in the concrete mix if the concrete properties are fresh. In addition, by using short fibres, the workability of the concrete mix increased as a result of extreme fiber balling reduction [51]. The strength of the composites can be further improved in 28 days by having palm oil fiber added to the composites.…”

Abstract. Nowadays, one of the most important construction materials is concrete. By the advances of the industries in the urban areas, concrete is considered as one of the highest demands. As a result, the large amount of unprocessed materials is needed for making concrete. In the meantime, the agricultural wastes and solid material disposal are giving serious damages to the environment. As a result, by employing the agricultural wastes as a cementitious material, the undesirable impacts of the concrete industry to the environment will be dramatically decreased. That's because the source of these newly developed concretes is both reliable and environmental friendly. In this study, the utilization of agricultural wastes as a complementary cementitious material for producing the concrete is explained. In addition, it discusses the possibility of deploying the agricultural wastes by considering their engineering, physical and chemical properties. In addition, the successful use of agricultural wastes from oil palm industry such as oil palm shell, palm oil fuel ash and palm oil fibre in the concrete mixture was reported.

“…An addition of fiber into the concrete mix can significantly improve the engineering properties of the concrete such as the flexural, tensile, impact and abrasion strength [3][4]. Many natural and synthetic fibers are utilized in concrete obtained from glass, carbon, aramid, polypropylene, and basalt rock.…”

This paper represents the outcomes of some latest trends of research in the field of concrete composites prepared with chopped basalt fibers (CBF) as fillers. The paper summarizes noticeable findings of the experimental studies carried out to demonstrate the advantages and limitations of the addition of CBF in a conventional concrete specifically. The review inspired to conclude that the effect of addition of chopped basalt fibers has been studied by performing tests for the workability of fresh mixes, compressive strength, splitting tensile strength and flexure strength with varying fractions and sizes of CBF. It was noticed that the workability reduced with addition of CBF and the strength properties showed an increment due to the CBF addition. However, lacking the explicit knowledge on the optimum dosage and preferred aspect ratio of CBF from the durability perspectives requires attention. Moreover, a compound usage of CBF with prevailing additives namely polymers, fly ash, silica fumes may be one of the potential areas for the researchers. Therefore, a need of extensive experimental study can be proposed dedicated to a full length experimental program for durability studies on concrete containing CBF can be proposed. The research outcomes indicated that addition of CBF into the concrete may prove advantageous to overcome the durability issues of concrete.
