“…The results indicate that the reference concrete flags without recycled steel fibers and crumbed rubber waste aggregate had a rupture force of 5.12 kN. When adding 0.125% recycled steel fibers, the failure load increased to 6 kN, and the reason is due to the role of the fibers in resisting failure and its transmission, which led to an increase in the failure force; in addition, the reinforcement with recycled steel fibre improves the tensile strength in the flags' tensile zone and enhances their flexural strength [30].…”

“…Another local study was conducted by Ref. Abdul Rasool et al [9] by using wire mesh reinforcement with different shapes and types (metal and plastic wire mesh) to improve the properties of precast concrete. The outcome of the study exhibited that the properties of the precast concrete can be developed by using reinforcing mesh.…”

A polyethylene terephthalate plastic material is widely used in Iraq for packages manufacturing, especially for the mineral water bottles. They turn out to be waste very rapidly due to their particular short period of use. Furthermore, the recycling amount of polyethylene terephthalate bottles is considerably fewer than the sales of virgin polyethylene terephthalate manufacture for public consumptions. In the current research, the results of rupture load, water absorption and density tests implemented on precast flooring concrete slabs reinforced by fibers prepared from waste polyethylene terephthalate bottles are reported. The fibers were prepared by the simple cutting way to the bottles of carbonated beverage, and then the fibers are incorporated in the ordinary concrete mix in different volume fraction and aspect ratio. The outcomes of the rupture load and water absorption of the plastics fibers reinforced precast flooring concrete slabs exhibited apparent increase when compared with the plain precast flooring concrete slabs. This can offer the potential and practical use of the waste plastic in the development of the production of precast flooring concrete slabs.

Concrete is well-known with its brittleness, low tensile strength and tensile strain capacities. This performance considered as one of the most crucial constraints that facing precast concrete industry. However, it could be improved by the addition of steel fibers which have been used widely in the last few decades. Hence, higher ductility and better arresting ability to crack propagation could be achieved. In Iraq, the precast concrete panels (flags) are commonly used for roofing and usually produced from plain concrete. This study aimed to add small volume fraction of steel fiber to the precast concrete panels to improve the handling and transportation process and assess their breaking load in according to the requirements of the Iraqi standard specification No.1107- 87. Concrete panels with (400×400mm) and different thicknesses (30 and 50mm) were produced. Different steel fiber volume fractions (0%, 0.25%, 0.5%, and 1%) were incorporated. The mechanical properties (compressive strength, splitting tensile strength, and flexural strength) for the concrete mixes were investigated. The test results of this study encourage the incorporation of small volume fraction of steel fiber in production of precast concrete panels to reduce the spoilage upon handling and transportation of precast concrete panels. The breaking load of steel fiber concrete panels has been improved by 142% relative to reference concrete panels. It was also revealed that the concrete panel thickness could be reduced when the steel fiber content increased, which could be of great interest with regards to the economic side. This is because of reducing the amount of raw materials used in production of concrete panels and thereby reducing the impact on the environment. The statistical analysis was accomplished by using the SPSS program.
