    abstract = {Concrete show many advantages related
mechanical characteristics and economic parts of the
construction, the brittle behaviour of the material remains
a big impediment for the seismic and other
implementations where flexible behaviour is basically
required. The study examines the utilize of dune sand as
fine aggregate in concrete and reinforced with
polypropylene fiber to developed properties of concrete.
In the present study the mix design of grade M25 (1:2:4)
with W/C = 0.6 was calculated to prepare the concrete
samples for the various proportion of polypropylene fiber
such as (0, 1, 1.5 and 2%). In each case, the cubes
compressive strength test was conducted. The results of
the study show that the compressive strength properties of
concrete utilizing dune sand improved by polypropylene
fiber reinforced. The experimental results show that 1%
content of polypropylene fiber slightly increase the
compressive strength but obviously enhances the
toughness index for the concrete, consequently it plays a
role of improving toughness in concrete. The study has
shown that dune sand can be used as economic and
readily available alternative to sea sand and can therefore
help to arrest the detrimental effects on the environment
caused due to excessive mining of sea sand. Finally,
the results of samples of various percentages of
polypropylene fibers in concrete have been compared and
the result of the study is explained.}
