“…These values represent a percentage of 0.7 %, -2.9 % and 9.3 % for PFC 0.2, PFC 0.4 and PFC 0.6 mixes. Kayali et al [5] also founded that increasing about 20 % in flexural strength for polypropylene fiber reinforced lightweight aggregate concrete at 0.56 % by volume fraction. The reason for the increase of flexural strength is the fracture process of polyolefin fiber reinforced foamed concrete consists of progressive debonding of fiber have slowed down the crack propagation.…”

“…[4] has investigated the properties of fiber reinforced lightweight concrete. Kayali et al [5] reported that polypropylene fiber addition of 0.56 % by volume of the lightweight aggregate concrete caused a 90 % increase in indirect tensile strength and 20 % increase in the modulus of rupture. Chen and Liu [6] also reported that the addition of steel fiber can significantly increase the split tensile strength of expanded polystyrene concrete and improve its shrinkage resistance properties.…”

Foam concrete is a lightweight concrete which is produced relatively inexpensively. However, due to its low strength and brittleness the application in building construction is rather limited. A study has been undertaken to investigate the effects of polyolefin fibers at a relatively low volume fraction (0 %, 0.2 %, 0.4 % and 0.6 %) on the compressive and flexural properties of foamed concrete. The foamed concrete was designed to achieve a target strength of 8-10 MPa with a density of 1600 kg/m3 at the age of 28 days. For each mixture, nine lOOxlOOxlOO mm cubes and three 100x100x500 mm beam were prepared. The compressive test was performed on cubes and three points loading flexural test on the beams was carried out in accordance to MS 26:Part 2: 1991. Test results showed that polyolefin fibers only slightly improved the compressive strength and flexural strength of foamed concrete by 4.3% and 9.3% respectively.

“…The static modulus of elasticity increased by about 28% with the inclusion of steel fibers. This could be due to the fact that steel fibers have high stiffness resulting in a higher modulus of elasticity for HSM [21]. However, the effect of using hybrid fibers on the static modulus of elasticity indicated that the use of 0.25% of palm fibers or 0.5% of palm fibers and Barchip fibers in hybrid combination was found to be much affective.…”

The production and use of durable materials in construction are considered as one of the most challenging things for the professional engineers. Therefore, this research was conducted to investigate the mechanical properties and the durability by using of different percentages of steel fiber with high-strength flowable mortar (HSFM) and also the use of the hybridization of steel fibers, palm fibers, and synthetic fiber (Barchip). Different experimental tests (compressive strength, splitting tensile strength, flexural strength, and static modulus of elasticity among others) were determined after 90 days of normal water curing and 180 days of seawater exposure. The results indicate that hybrid fibers of 1.5% steel fibers + 0.25% palm fibers + 0.25% Barchip fibers provide significant improvement in the different mechanical properties of HSFM. Besides, the hybridization of fibers was found to be effective in the terms of durability (exposure to seawater). Therefore, the minimum reduction in static modulus of elasticity, compressive, splitting and flexural strength was obtained for the HSFM mixes of hybrid fibers using steel fibers with palm fibers and also for the use of steel, palm, and Barchip fibers.

“…Therefore, it is found out that addition of steel fiber in concrete mixture can decrease the mentioned brittleness 19,20 . This method is commonly used for reducing lightweight aggregate concrete brittleness 12,19,21,22 .

Nowadays, the use of different waste fibers in concrete has started to increase rapidly due to some reasons such as economic savings and positive effects on the environment. In this study, waste steel wires taken from reinforcement and formwork which were previously utilized in construction projects, were employed in structural lightweight concrete (SLWC). The objective was to investigate the possibility of using this type of fiber as reinforcement in the SLWC. Compressive, tensile, flexural and impact tests were performed for investigating the mechanical properties of 28-day reinforced lightweight concrete specimens with the waste wires. The percentage of wire in the fiber reinforced concrete (FRC) was 0.25%, 0.5% and 0.75% in the volume fraction of the concrete. According to the results, by using waste wires, flexural, tensile and impact characteristics of SLWC were effectively improved. Moreover, it was concluded that waste steel wires could be used as a suitable micro reinforcement in the SLWC.
