AB  - This investigation looks at the additive impact of polypropylene fibers to the concrete properties.
The structural performance of polypropylene fibers concrete double tee beams was also inspected. Four-point
bending tests were prepared with fiber content (0.5, 1.0, 1.5 and 2% by weight) to inspect the flexural strength
and deflection of double tee beams. Additionally, the impact of PPF on the beams with various amounts of
transverse steel reinforcement was explored. The outcomes demonstrate that fiber addition improved the
concrete properties in general and enhanced the ductility and the load bearing capacity, control of cracking
of the double tee beams remarkably. The highest increase in loading was 21.98%, at the same manner an
increases were observed in the deflection values under the largest load compared to the control sample.
Deflection was decreases with respect to the same loading stages with the increase of fiber contents, the
highest recorded decrease was 21.47%. The polypropylene fiber can be used as a solution for the cases with
stirrups congestion since the ultimate load was increases with the same spacing of stirrups. The polypropylene
fiber usage was upheld as hopeful technics for the different problems of concrete cracking in destructive
situations.
