Flexural Investigation Of Fibrous Concrete Slabs Incorporating Pet Wastes As Sand Replacement
In this paper, the effect of polyethylene terephthalate waste (PET) on the bending behavior of one-way reinforced fibrous concrete slabs was studied. seven different percentages of PET as sand replacement by weight were used: 0%, 5%, 10%, 15%, 20%, 30%, and 50% reinforced by ratio 1.5% of polypropyl...

| description | In this paper, the effect of polyethylene terephthalate waste (PET) on the bending behavior of one-way reinforced fibrous concrete slabs was studied. seven different percentages of PET as sand replacement by weight were used: 0%, 5%, 10%, 15%, 20%, 30%, and 50% reinforced by ratio 1.5% of polypropylene fibers of the concrete mixture volume. Seven concrete slab specimens for each replacement ratio of PET with dimensions of 1500 × 500 × 80 mm were tested, in addition to reference slab. The specimens were tested using a four-point load setup, the measurements included failure load, maximum deflection, flexural strain, ductility index, energy absorption, stiffness, first crack load, and crack pattern. Based on maximum load capacity, 10% PET wastes as sand replacement is the optimum proportion in fibrous concrete mixture with 1.5% polypropylene fiber, yielding an ultimate failure load of 51KN. In additional, the values of the ultimate failure load for the mixtures containing PET waste were change by 4.22%, 14.14%, 26.55%, 11.66%, -0.74%, -5.71% and -57.82%, compared to the reference mixture. Other parameters such as maximum deflection, strain, and energy absorption is increase when the percentage of PET increasing in range 5-30% but, the ductility index is increasing in rang 5-50% in concrete slabs. On the other hand, initial stiffness and secant stiffness were found to be lower when the ratio of PET increasing in range 5-30%, 5-50%, respectively. |
