SUMMARY
In this research, the effect of adding fibres from plastic bags waste to the Concrete mixed with local materials, its compressive strength and tensile strength were studied Percentages of cement weight (0.5-2%) while FP plastic fibres I used a reference mixture that is free of any additive and another that contains fibre w/c in the same proportions as the plastic fibres. The ratio of water to FPP polymeric cement For all mixtures are 0.50% and 0.55% and stabilized or weighed cement and large aggregates with Adjust or weigh the small aggregate to suit or weigh the added fibres. The results showed that with 1% with the first mixture and Fp, the compressive strength increased by 3.5%, corresponding to the percentage of fibres 2% of its resistance in the second Fp-free reference mixture is more than 3.9% at fibres. Concrete's tensile strength increases with the first mixture by 26% to 0%.Added from the weight of cement 1% to 1.5%, it increases, and on the other hand, it increases The tensile strength is very similar to that of polypropylene-reinforced concrete To improve the tensile properties of concrete. The density of concrete FP on fibre capacity Those containing plastic are lighter than those containing polypropylene Light concrete, but it is necessary to pay attention to the presence of voids and the possibility of separation for concrete. Production of fibre-reinforced concrete from industrial waste is beneficial Environmental disposal of industrial waste that has a harmful environmental impact and This waste is plastic waste in addition to its availability and cheapness.
