“…Steel fibers influence the mechanical properties of concrete and mortar in all failure modes, especially those that induce fatigue and tensile stress, e.g., direct tension, bending, impact, and shear [9]- [10]. With the inclusion of hooked end fiber improve the mechanical properties of concrete [11]- [12].…”

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.

“…Song, J.C. Wu, S. Hwang and B.C.Sheu [5] investigated and found that the Hybrid fiber-reinforced concrete showed smaller variation in the first-crack strength and failure strength, although larger scatter in the percentage increase were observed in the number of post-first-crack blows, and strength reliability of steel-polypropylene hybrid fiber-reinforced concrete when compared to steel fiber reinforced concrete in drop weight test. Mahmoud Nili and V. Afrough sabet [6] reported that the propagation of cracks under stress, and enhance the impact strength, toughness and ductility of concrete and when steel fiber is introduced into the specimens including silica fume, the impact resistance and the ductility of the resulting concrete are considerably increased.…”

“…Both normal strength concrete and highstrength concrete are brittle, with the degree of brittleness increasing with increasing strength [20]. Nili and Afroughsabet [21] showed that the silica fume improves the compressive strength of the higher ages by improving the conjunction of aggregates with cement paste. Also, the simultaneous use of silica soot and fiber in concrete mixtures will lead to an effective increase in the flexural strength of concrete.…”

In the present paper, the effect of Nano silica on mechanical properties and durability of concrete containing polypropylene fibers has been investigated. Here, the length and length to diameter ratio of used polypropylene fibers were considered to be fixed and equal to 18 mm and 600 respectively and the cement content was 479 kg/m 3 . The effect of fibers and Nano silica in four different percentages for each one at 0.1, 0.2, 0.3 and 0.4 percent by volume for fibers and 3 percent for Nano silica in concrete with water to cement ratio of 0.33, 0.36, 0.4, 0.44 and 0.5 have been compared and evaluated. In total, more than 425 cubic and cylindrical specimens were made according to ASTM standards. Finally, samples of polypropylene fiber containing Nano-silica were tested under compressive loads, flexural strength, indirect tensile strength (Brazilian test), abrasion resistance, permeability and porosity and their mechanical properties were evaluated. The test results showed a significant increase in mechanical properties improvement and durability of concrete. Compressive strength, tensile strength, flexural strength and abrasion resistance (of concrete) increased up to 55%, 25%, 49%, and 45% respectively. Also, considerable reduction of hydraulic conductivity coefficient to 50% indicates high durability of these types of concrete.
