This investigation aims to improve some of the mechanical properties of concrete such as
compressive strength, flexural strength, and modulus of elasticity, by using different percentages of
polypropylene fibers, and also studying the durability of concrete for freeze-thaw cycles. the study
shows a small increment in compressive strength due to adding fibers which were 28.3% compared
with increment in flexural strength which was perfect (about 191%), modulus of elasticity also
increased by adding fibers. The durability of concrete against freezing-thaw cycles for all mixes
was studied. Fiber-reinforced concrete shows more durability against freezing-thawing cycles and
less reduction in strength compared with reference mixes without fibers,21.5% reduction in strength
for optimum polypropylene fiber concrete while the reduction in strength for normal concrete was
found 54.2% in this study.
